+Additional components to use esphome with a M5StickC
+Mostly a work in progress - this compoe
+
+- axp192 : power management - configuration hard coded for the M5StickC - should be made more generic
+  Must be present to initialize the screen power
+  Can be also used to read some of the power info - most sensors aren't published yet
+  Mostly the AXP192 from M5Stack sample code adapted for esphome
+- st7735 : TFT screen  - configuration hard coded for the M5StickC - should be made more generic
+  Adapted from https://github.com/musk95/esphome-1/tree/dev/esphome/components/st7789v + M5StickC sample code for the init
