esphome components for the M5StickC

NOTE: A st7735 screen component is now part of esphome and a more complete axp192 component can be found here : https://gitlab.com/geiseri/esphome_extras.git

---

Additional components to use esphome with a M5StickC.
Mostly a work in progress.
Copy the components to a custom_components directory next to your .yaml configuration file.

• 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

esphome-m5stickc's Issues

esp-idf support?

I am using a fork of your repository - https://github.com/martydingo/esphome-axp192 - to enable my M5Stack Core2. As soon as I attempted to move from an arduino to the esp-idf framework required by voice_assistant, I got an error about ESP.h (no detail) related to the axp192 component.

Can your component be used with esp-idf? I believe ESPHome is working towards a permanent move to that framework so it is only a matter of time before this will be come a big problem :(

Cannot upload the sample code

Hi.
First of all, thank you!!! :)

I'm trying to upload the sample code on my m5stick but I get this error:

...
Serial port COM15
Connecting....
Chip is ESP32-PICO-D4 (revision 1)

A fatal error occurred: Timed out waiting for packet header

On the stick there is a sample code uploaded with che arduino IDE and it's working.

Any suggestion?

Thank you!

Upgrade to change the brightness from HA

Thanks for your job
It would be possible to add a sensor to be able to change the brightness from HA of the screen?

problems on installation on home assistant

Hello,

I'm trying to follow the steps on this github, however facing some issues
I have a M5Stick-C model and want to try to connect this with some old probes installed on my bathrooms and allow me to view each one a has leak alarms. but first would like to try this steps.

As you can see on the image, at the end it fails. can someone give some shadow to achieve this? I'm a bit new with ESPs and M5Stack

display stays black

I tried using exactly the sample YAML file, verbatim except for:

• changing to a font file that I already had in my environment
• removing references to the axp192 (different problem :-( )

So far, I can get nothing to appear on the screen. I even simplified the display lambda down to just a constant string, but still nothing. Logging and blinky lights show that button presses are working as expected. I am using the latest esphome (1.14.5).

Is it possible that something has changed in esphome in the last couple of months to throw a wrench into this?
My m5stick-c is recently purchased. Could there be a hardware change that causes the problem? (The demo program that came on the m5stick-c worked fine until I flashed over it.)

I'm just starting to troubleshoot this, so I'm wondering if someone has hit this already and knows the simple answer.

V2022.3.0 of esphome has Broken this component

The axp192 part will no longer compile.

Platform not Found: display.st7735 and sensor.axp192

No chance to install. Unfortunately, that doesn't work for me. I have Homeassisant running on a raspi3. custom_components is available. Can you describe this in more detail?

Detect charging vs. battery?

Is it possible to detect if the m5stick is running on battery or charging?

version of espHome

It is worth noting the required version of espHome is 1.16.2 due to the color.to_rgb_565 requirement.
Both dev and latest have this removed.

Display stays off after power cycle

After flashing esphome with your AXP component the display stays on while the m5stick has power. After the first powerdown and bootup it stays off though. Is it possible that I'm missing a switch or output that isn't in the sample-config which is necessary to turn the backlight on?

How can you turn the display on and off?

Thanks for your help.

Q: ESPHome 2023.6.4 Platform not found: 'sensor.axp192'?

Has compilation broken again?
