[request] set_analogGain() function is required

[msfujino]

Summary

For AD conversion, a function like set_analogGain() is needed to set the gain as well as the set_reference() function to set the reference voltage.

Hi @msfujino,
Thanks for your suggestion!
If you need to modify the ADC analog gain, you can adjust this variable:

arduino/cores/silabs/adc.cpp

Line 195 in c51e6c0

all_configs.configs[0].analogGain = iadcCfgAnalogGain1x;

(If you're using the Arduino Nano Matter, you can find the available values here).

If you'd like to contribute, feel free to create a PR implementing set_analogGain(), and I'll be happy to review it! 😄

Thank you for your response.
I had already tried the patch to deal with the problem and knew it would work, but for compatibility, I thought there should be a set_analogGain().
Unfortunately, I don't have the skills to create a new function. I would appreciate it if you could consider this in the next release.

I have created a function set_gain(), but I can't figure out how to post it.
Is there any documentation available?
