ADC is not working on BK7231n modules #5201

Open redskinhu opened 11 months ago

redskinhu commented 11 months ago

The problem

I have couple of BK7231n modules in different devices. I tried to use the ADC but I got incorrect and constants (2.048V) values independently the voltage on the ADC on all devices.

It looks the ADC is not working.

Which version of ESPHome has the issue?

2023.11.6

What type of installation are you using?

Home Assistant Add-on

Which version of Home Assistant has the issue?

2023.11.2

What platform are you using?

BK72XX

Board

BK7231n onboard / CB2S / CBU

Component causing the issue

adc

Example YAML snippet

sensor:
  - platform: adc
    pin: ADC3
    name: "${upper_devicename} VCC"
    unit_of_measurement: "V"

Anything in the logs that might be useful for us?

I'm using a few devices with BK7231Ts and ADC works fine there. So maybe it's something N-specific.

For beken chips ESPHome uses libretiny, so please head on to libretiny issues and report it there - you will get help faster.

Thanks

@redskinhu there's a pending fix libretiny-eu/libretiny#220, would you like to test it?

redskinhu commented 11 months ago

Hello @szupi-ipuzs

I installed this: v1.4.1 on generic-bk7231n-qfn32-tuya, compiled at Dec 15 2023 19:14:29, GCC 10.3.1 (-O1) through ESPHome.

ADC behavior has not changed, but I think this is not the right way to build the FW with the modified libretiny.

Any advice?

Thx
