* fix interrupt handling for the ln882h

- all GPIOS can generate interrupts
- added calls to NVIC_SetPriority/NVIC_EnableIRQ/NVIC_DisableIRQ

* fix clang formatting error

* only call NVIC_DisableIRQ if no other gpio is using an interrupt

* fix (again) clang-format errors

* add IRQ capability on all pins

* don't bother with NVIC_DisableIRQ

* use pin->gpio instead of interruptNumber, use macro GPIO_GET_PORT for clarity

* Mark interrupts as supported for the LN882H

-PlatformIO development platform for IoT modules manufactured by Tuya Inc.
+PlatformIO development platform for BK7231, RTL8710 and LN882H IoT chips.
 
 The main goal of this project is to provide a usable build environment for IoT developers. While also providing vendor SDKs as PlatformIO cores,
-the project focuses on developing working Arduino-compatible cores for supported platforms. The cores are inspired by Espressif's official core for ESP32,
-which should make it easier to port/run existing ESP apps on Tuya IoT (and 3-rd party) platforms.
+the project focuses on developing working Arduino-compatible cores for supported families. The cores are inspired by Espressif's official core for ESP32,
+which should make it easier to port/run existing ESP apps on less-common, unsupported IoT modules.
 
-LibreTuya also provides a common interface for all platform implementations. The interface is based on ESP32 official libraries.
+**There's an [ESPHome port](https://docs.libretiny.eu/docs/projects/esphome/) based on LibreTiny, which supports BK7231 and RTL8710B chips.**
 
 **Note:** this project is work-in-progress.
 
-## Usage
+<div align="center" markdown>
 
-1. [Install PlatformIO](https://platformio.org/platformio-ide)
-2. `platformio platform install libretuya`
-3. Create a project, build it and upload!
-4. See the [docs](docs/README.md) for any questions/problems.

-
-### Realtek Ameba
-
-The logic behind naming of Realtek chips and their series took me some time to figure out:
-- RTL8xxxA - Ameba1/Ameba Series
-- RTL8xxxB - AmebaZ Series
-- RTL8xxxC - AmebaZ2/ZII Series
-- RTL8xxxD - AmebaD Series
-
-As such, there are numerous CPUs with the same numbers but different series, which makes them require different code and SDKs.
-- [RTL8195AM](https://www.realtek.com/en/products/communications-network-ics/item/rtl8195am)
-- RTL8710AF (found in amb1_arduino)
-- [RTL8711AM](https://www.realtek.com/en/products/communications-network-ics/item/rtl8711am)
-- [RTL8710BN](https://www.realtek.com/en/products/communications-network-ics/item/rtl8710bn)
-- RTL8710BX (found in Tuya product pages)
-- RTL8710B? (found in amb1_sdk)
-- RTL8711B? (found in amb1_sdk)
-- [RTL8710CM](https://www.realtek.com/en/products/communications-network-ics/item/rtl8710cm)
-- RTL8722CSM (found in ambd_arduino)
-- RTL8720DN (found in ambd_arduino)
-- [RTL8721DM](https://www.realtek.com/en/products/communications-network-ics/item/rtl8721dm)
-- RTL8722DM (found in ambd_arduino)
-- and probably many more
-
-Different Ameba series are not compatible with each other. Apparently, there isn't an official public SDK for AmebaZ that can support C++ properly.

-# SPIFFS (SPI Flash File System) 
-**V0.3.4**
-
-Copyright (c) 2013-2016 Peter Andersson (pelleplutt1976 at gmail.com)
-
-For legal stuff, see [LICENSE](https://github.com/pellepl/spiffs/blob/master/LICENSE). Basically, you may do whatever you want with the source. Use, modify, sell, print it out, roll it and smoke it - as long as I won't be held responsible.
-
-Love to hear feedback though!
-
-
-## INTRODUCTION
-
-Spiffs is a file system intended for SPI NOR flash devices on embedded targets.
-
-Spiffs is designed with following characteristics in mind:
- - Small (embedded) targets, sparse RAM without heap
- - Only big areas of data (blocks) can be erased
- - An erase will reset all bits in block to ones
- - Writing pulls one to zeroes
- - Zeroes can only be pulled to ones by erase
- - Wear leveling
-
-
-## FEATURES
-
-What spiffs does:
- - Specifically designed for low ram usage
- - Uses statically sized ram buffers, independent of number of files
- - Posix-like api: open, close, read, write, seek, stat, etc
- - It can be run on any NOR flash, not only SPI flash - theoretically also on embedded flash of an microprocessor
- - Multiple spiffs configurations can be run on same target - and even on same SPI flash device
- - Implements static wear leveling 
- - Built in file system consistency checks
- 
-What spiffs does not:
- - Presently, spiffs does not support directories. It produces a flat structure. Creating a file with path *tmp/myfile.txt* will create a file called *tmp/myfile.txt* instead of a *myfile.txt* under directory *tmp*. 
- - It is not a realtime stack. One write operation might take much longer than another.
- - Poor scalability. Spiffs is intended for small memory devices - the normal sizes for SPI flashes. Going beyond ~128MB is probably a bad idea. This is a side effect of the design goal to use as little ram as possible.
- - Presently, it does not detect or handle bad blocks.
-
- 
-## MORE INFO 
- 
-See the [wiki](https://github.com/pellepl/spiffs/wiki) for configuring, integrating and using spiffs.
- 
-For design, see [docs/TECH_SPEC](https://github.com/pellepl/spiffs/blob/master/docs/TECH_SPEC).
-
-For a generic spi flash driver, see [this](https://github.com/pellepl/spiflash_driver).
-
-## HISTORY
-
-### 0.3.4
-- Added user callback file func.
-- Fixed a stat bug with obj id.
-- SPIFFS_probe_fs added
-- Add possibility to compile a read-only version of spiffs
-- Make magic dependent on fs length, if needed (see #59 & #66) (thanks @hreintke)
-- Exposed SPIFFS_open_by_page_function
-- Zero-size file cannot be seek #57 (thanks @lishen2)
-- Add tell and eof functions #54 (thanks @raburton)
-- Make api string params const #53 (thanks @raburton)
-- Preserve user_data during mount() #51 (thanks @rojer)
-
-New API functions:
-- `SPIFFS_set_file_callback_func` - register a callback informing about file events
-- `SPIFFS_probe_fs` - probe a spi flash trying to figure out size of fs
-- `SPIFFS_open_by_page` - open a file by page index
-- `SPIFFS_eof` - checks if end of file is reached
-- `SPIFFS_tell` - returns current file offset
-
-New config defines:
-- `SPIFFS_READ_ONLY`
-- `SPIFFS_USE_MAGIC_LENGTH`
-
-### 0.3.3
-**Might not be compatible with 0.3.2 structures. See issue #40**
-- Possibility to add integer offset to file handles
-- Truncate function presumes too few free pages #49
-- Bug in truncate function #48 (thanks @PawelDefee)
-- Update spiffs_gc.c - remove unnecessary parameter (thanks @PawelDefee)
-- Update INTEGRATION docs (thanks @PawelDefee)
-- Fix pointer truncation in 64-bit platforms (thanks @igrr)
-- Zero-sized files cannot be read #44 (thanks @rojer)
-- (More) correct calculation of max_id in obj_lu_find #42 #41 (thanks @lishen2)
-- Check correct error code in obj_lu_find_free #41 (thanks @lishen2)
-- Moar comments for SPIFFS_lseek (thanks @igrr)
-- Fixed padding in spiffs_page_object_ix #40 (thanks @jmattsson @lishen2)
-- Fixed gc_quick test (thanks @jmattsson)
-- Add SPIFFS_EXCL flag #36 
-- SPIFFS_close may fail silently if cache is enabled #37

-* USING SPIFFS
-
-TODO
-
-
-* SPIFFS DESIGN
-
-Spiffs is inspired by YAFFS. However, YAFFS is designed for NAND flashes, and
-for bigger targets with much more ram. Nevertheless, many wise thoughts have
-been borrowed from YAFFS when writing spiffs. Kudos!
-
-The main complication writing spiffs was that it cannot be assumed the target
-has a heap. Spiffs must go along only with the work ram buffer given to it. 
-This forces extra implementation on many areas of spiffs.
-
-
-** SPI flash devices using NOR technology
-
-Below is a small description of how SPI flashes work internally. This is to
-give an understanding of the design choices made in spiffs.
-
-SPI flash devices are physically divided in blocks. On some SPI flash devices,
-blocks are further divided into sectors. Datasheets sometimes name blocks as 
-sectors and vice versa.
-
-Common memory capacaties for SPI flashes are 512kB up to 8MB of data, where
-blocks may be 64kB. Sectors can be e.g. 4kB, if supported. Many SPI flashes 
-have uniform block sizes, whereas others have non-uniform - the latter meaning 
-that e.g. the first 16 blocks are 4kB big, and the rest are 64kB.
-
-The entire memory is linear and can be read and written in random access. 
-Erasing can only be done block- or sectorwise; or by mass erase.
-
-SPI flashes can normally be erased from 100.000 up to 1.000.000 cycles before
-they fail.
-
-A clean SPI flash from factory have all bits in entire memory set to one. A
-mass erase will reset the device to this state. Block or sector erasing will
-put the all bits in the area given by the sector or block to ones. Writing to a
-NOR flash pulls ones to zeroes. Writing 0xFF to an address is simply a no-op. 
-
-Writing 0b10101010 to a flash address holding 0b00001111 will yield 0b00001010.
-
-This way of "write by nand" is used considerably in spiffs.
-
-Common characteristics of NOR flashes are quick reads, but slow writes.
-
-And finally, unlike NAND flashes, NOR flashes seem to not need any error 
-correction. They always write correctly I gather.
-
-
-** Spiffs logical structure
-
-Some terminology before proceeding. Physical blocks/sectors means sizes stated
-in the datasheet. Logical blocks and pages is something the integrator choose.
-
-
-** Blocks and pages
-
-Spiffs is allocated to a part or all of the memory of the SPI flash device. 
-This area is divided into logical blocks, which in turn are divided into 
-logical pages. The boundary of a logical block must coincide with one or more 
-physical blocks. The sizes for logical blocks and logical pages always remain
-the same, they are uniform.
-
-Example: non-uniform flash mapped to spiffs with 128kB logical blocks
-
-PHYSICAL FLASH BLOCKS               SPIFFS LOGICAL BLOCKS: 128kB
-
-+-----------------------+   - - -   +-----------------------+

-A logical block is divided further into a number of logical pages. A page 
-defines the smallest data holding element known to spiffs. Hence, if a file
-is created being one byte big, it will occupy one page for index and one page
-for data - it will occupy 2 x size of a logical page on flash.
-So it seems it is good to select a small page size.
-
-Each page has a metadata header being normally 5 to 9 bytes. This said, a very
-small page size will make metadata occupy a lot of the memory on the flash. A
-page size of 64 bytes will waste 8-14% on metadata, while 256 bytes 2-4%.
-So it seems it is good to select a big page size.
-
-Also, spiffs uses a ram buffer being two times the page size. This ram buffer
-is used for loading and manipulating pages, but it is also used for algorithms 
-to find free file ids, scanning the file system, etc. Having too small a page
-size means less work buffer for spiffs, ending up in more reads operations and
-eventually gives a slower file system.
-
-Choosing the page size for the system involves many factors:
- - How big is the logical block size
- - What is the normal size of most files
- - How much ram can be spent
- - How much data (vs metadata) must be crammed into the file system
- - How fast must spiffs be
- - Other things impossible to find out
- 
-So, chosing the Optimal Page Size (tm) seems tricky, to say the least. Don't 
-fret - there is no optimal page size. This varies from how the target will use
-spiffs. Use the golden rule:
-
-        ~~~   Logical Page Size = Logical Block Size / 256   ~~~
-
-This is a good starting point. The final page size can then be derived through 
-heuristical experimenting for us non-analytical minds.
-
-
-** Objects, indices and look-ups
-
-A file, or an object as called in spiffs, is identified by an object id. 
-Another YAFFS rip-off. This object id is a part of the page header. So, all 
-pages know to which object/file they belong - not counting the free pages.
-
-An object is made up of two types of pages: object index pages and data pages.
-Data pages contain the data written by user. Index pages contain metadata about
-the object, more specifically what data pages are part of the object.
-
-The page header also includes something called a span index. Let's say a file
-is written covering three data pages. The first data page will then have span 
-index 0, the second span index 1, and the last data page will have span index
-2. Simple as that. 
-
-Finally, each page header contain flags, telling if the page is used, 
-deleted, finalized, holds index or data, and more.
-
-Object indices also have span indices, where an object index with span index 0
-is referred to as the object index header. This page does not only contain 
-references to data pages, but also extra info such as object name, object size
-in bytes, flags for file or directory, etc.
-
-If one were to create a file covering three data pages, named e.g. 
-"spandex-joke.txt", given object id 12, it could look like this:
-
-PAGE 0  <things to be unveiled soon>
-
-PAGE 1  page header:   [obj_id:12  span_ix:0  flags:USED|DATA]
-        <first data page of joke>
-
-PAGE 2  page header:   [obj_id:12  span_ix:1  flags:USED|DATA]
-        <second data page of joke>
-
-PAGE 3  page header:   [obj_id:545 span_ix:13 flags:USED|DATA]
-        <some data belonging to object 545, probably not very amusing>
-
-PAGE 4  page header:   [obj_id:12  span_ix:2  flags:USED|DATA]
-        <third data page of joke>
-
-PAGE 5  page header:   [obj_id:12  span_ix:0  flags:USED|INDEX]
-        obj ix header: [name:spandex-joke.txt  size:600 bytes  flags:FILE] 
-        obj ix:        [1 2 4]
-        
-Looking in detail at page 5, the object index header page, the object index
-array refers to each data page in order, as mentioned before. The index of the
-object index array correlates with the data page span index.
-
-                            entry ix:  0 1 2
-                              obj ix: [1 2 4]
-                                       | | |
-    PAGE 1, DATA, SPAN_IX 0    --------/ | |
-      PAGE 2, DATA, SPAN_IX 1    --------/ |
-        PAGE 4, DATA, SPAN_IX 2    --------/
-        
-Things to be unveiled in page 0 - well.. Spiffs is designed for systems low on 
-ram. We cannot keep a dynamic list on the whereabouts of each object index 
-header so we can find a file fast. There might not even be a heap! But, we do 
-not want to scan all page headers on the flash to find the object index header.
-
-The first page(s) of each block contains the so called object look-up. These 
-are not normal pages, they do not have a header. Instead, they are arrays 
-pointing out what object-id the rest of all pages in the block belongs to.
-
-By this look-up, only the first page(s) in each block must to scanned to find 
-the actual page which contains the object index header of the desired object.
-
-The object lookup is redundant metadata. The assumption is that it presents 
-less overhead reading a full page of data to memory from each block and search
-that, instead of reading a small amount of data from each page (i.e. the page 
-header) in all blocks. Each read operation from SPI flash normally contains 
-extra data as the read command itself and the flash address. Also, depending on
-the underlying implementation, other criterions may need to be passed for each 
-read transaction, like mutexes and such.
-
-The veiled example unveiled would look like this, with some extra pages:
-
-PAGE 0  [  12   12  545   12   12   34   34    4    0    0    0    0 ...]
-PAGE 1  page header:   [obj_id:12  span_ix:0  flags:USED|DATA] ...
-PAGE 2  page header:   [obj_id:12  span_ix:1  flags:USED|DATA] ...
-PAGE 3  page header:   [obj_id:545 span_ix:13 flags:USED|DATA] ...
-PAGE 4  page header:   [obj_id:12  span_ix:2  flags:USED|DATA] ...
-PAGE 5  page header:   [obj_id:12  span_ix:0  flags:USED|INDEX] ...
-PAGE 6  page header:   [obj_id:34  span_ix:0  flags:USED|DATA] ...
-PAGE 7  page header:   [obj_id:34  span_ix:1  flags:USED|DATA] ...
-PAGE 8  page header:   [obj_id:4   span_ix:1  flags:USED|INDEX] ...
-PAGE 9  page header:   [obj_id:23  span_ix:0  flags:DELETED|INDEX] ...
-PAGE 10 page header:   [obj_id:23  span_ix:0  flags:DELETED|DATA] ...
-PAGE 11 page header:   [obj_id:23  span_ix:1  flags:DELETED|DATA] ...
-PAGE 12 page header:   [obj_id:23  span_ix:2  flags:DELETED|DATA] ...
-...
-
-Ok, so why are page 9 to 12 marked as 0 when they belong to object id 23? These
-pages are deleted, so this is marked both in page header flags and in the look
-up. This is an example where spiffs uses NOR flashes "nand-way" of writing.
-
-As a matter of fact, there are two object id's which are special:
-
-obj id 0 (all bits zeroes) - indicates a deleted page in object look up  
-obj id 0xff.. (all bits ones) - indicates a free page in object look up 
-
-Actually, the object id's have another quirk: if the most significant bit is
-set, this indicates an object index page. If the most significant bit is zero,
-this indicates a data page. So to be fully correct, page 0 in above example 
-would look like this:
-
-PAGE 0  [  12   12  545   12  *12   34   34   *4    0    0    0    0 ...]
-
-where the asterisk means the msb of the object id is set.
-
-This is another way to speed up the searches when looking for object indices.
-By looking on the object id's msb in the object lookup, it is also possible 
-to find out whether the page is an object index page or a data page.

-* When mending lost pages, also see if they fit into length specified in object index header
-
-SPIFFS2 thoughts
-
-* Instead of exact object id:s in the object lookup tables, use a hash of span index and object id.
-  Eg. object id xor:ed with bit-reversed span index.
-  This should decrease number of actual pages that needs to be visited when looking thru the obj lut.
-
-* Logical number of each block. When moving stuff in a garbage collected page, the free
-  page is assigned the same number as the garbage collected. Thus, object index pages do not have to
-  be rewritten.
-
-* Steal one page, use as a bit parity page. When starting an fs modification operation, write one bit
-  as zero. When ending, write another bit as zero. On mount, if number of zeroes in page is uneven, a
-  check is automatically run.

- * spiffs_check.c
- *
- * Contains functionality for checking file system consistency
- * and mending problems.
- * Three levels of consistency checks are implemented:
- *
- * Look up consistency
- *   Checks if indices in lookup pages are coherent with page headers
- * Object index consistency
- *   Checks if there are any orphaned object indices (missing object index headers).
- *   If an object index is found but not its header, the object index is deleted.
- *   This is critical for the following page consistency check.
- * Page consistency
- *   Checks for pages that ought to be indexed, ought not to be indexed, are multiple indexed
- *

-/* SPIFFS layout
- *
- * spiffs is designed for following spi flash characteristics:
- *   - only big areas of data (blocks) can be erased
- *   - erasing resets all bits in a block to ones
- *   - writing pulls ones to zeroes
- *   - zeroes cannot be pulled to ones, without erase
- *   - wear leveling
- *
- * spiffs is also meant to be run on embedded, memory constraint devices.
- *
- * Entire area is divided in blocks. Entire area is also divided in pages.
- * Each block contains same number of pages. A page cannot be erased, but a
- * block can be erased.
- *
- * Entire area must be block_size * x
- * page_size must be block_size / (2^y) where y > 2
- *
- * ex: area = 1024*1024 bytes, block size = 65536 bytes, page size = 256 bytes
- *
- * BLOCK 0  PAGE 0       object lookup 1
- *          PAGE 1       object lookup 2
- *          ...
- *          PAGE n-1     object lookup n
- *          PAGE n       object data 1
- *          PAGE n+1     object data 2
- *          ...
- *          PAGE n+m-1   object data m
- *
- * BLOCK 1  PAGE n+m     object lookup 1
- *          PAGE n+m+1   object lookup 2
- *          ...
- *          PAGE 2n+m-1  object lookup n
- *          PAGE 2n+m    object data 1
- *          PAGE 2n+m    object data 2
- *          ...
- *          PAGE 2n+2m-1 object data m
- * ...
- *
- * n is number of object lookup pages, which is number of pages needed to index all pages
- * in a block by object id
- *   : block_size / page_size * sizeof(obj_id) / page_size
- * m is number data pages, which is number of pages in block minus number of lookup pages
- *   : block_size / page_size - block_size / page_size * sizeof(obj_id) / page_size
- * thus, n+m is total number of pages in a block
- *   : block_size / page_size
- *
- * ex: n = 65536/256*2/256 = 2, m = 65536/256 - 2 = 254 => n+m = 65536/256 = 256
- *
- * Object lookup pages contain object id entries. Each entry represent the corresponding
- * data page.
- * Assuming a 16 bit object id, an object id being 0xffff represents a free page.
- * An object id being 0x0000 represents a deleted page.
- *
- * ex: page 0 : lookup : 0008 0001 0aaa ffff ffff ffff ffff ffff ..
- *     page 1 : lookup : ffff ffff ffff ffff ffff ffff ffff ffff ..
- *     page 2 : data   : data for object id 0008
- *     page 3 : data   : data for object id 0001
- *     page 4 : data   : data for object id 0aaa
- *     ...
- *
- *
- * Object data pages can be either object index pages or object content.
- * All object data pages contains a data page header, containing object id and span index.
- * The span index denotes the object page ordering amongst data pages with same object id.
- * This applies to both object index pages (when index spans more than one page of entries),
- * and object data pages.
- * An object index page contains page entries pointing to object content page. The entry index
- * in a object index page correlates to the span index in the actual object data page.
- * The first object index page (span index 0) is called object index header page, and also
- * contains object flags (directory/file), size, object name etc.
- *
- * ex:
- *  BLOCK 1
- *    PAGE 256: objectl lookup page 1
- *      [*123] [ 123] [ 123] [ 123]
- *      [ 123] [*123] [ 123] [ 123]
- *      [free] [free] [free] [free] ...
- *    PAGE 257: objectl lookup page 2
- *      [free] [free] [free] [free] ...
- *    PAGE 258: object index page (header)
- *      obj.id:0123 span.ix:0000 flags:INDEX
- *      size:1600 name:ex.txt type:file
- *      [259] [260] [261] [262]
- *    PAGE 259: object data page
- *      obj.id:0123 span.ix:0000 flags:DATA
- *    PAGE 260: object data page
- *      obj.id:0123 span.ix:0001 flags:DATA
