LED diode #54

How can I control user LED diode?

Neutree commented 1 month ago 
echo none > /sys/class/leds/led-user/trigger
echo 1 > /sys/class/leds/led-user/brightness
echo 0 > /sys/class/leds/led-user/brightness

and you can find control code in MaixPy also at https://github.com/sipeed/MaixCDK/blob/main/components/peripheral/port/maixcam/maix_gpio.cpp

OK, unfortunately I do not see it.

sudo ls /sys/class/leds/
:heartbeat  mmc0::  mmc1::

But I am using https://github.com/Fishwaldo/sophgo-sg200x-debian/, it seems it is not implemented there. How can I do it by myself?

Also, how can I access GPIO's (read and write), do you have any example? Because it could be possible to solder my own LED to GPIO, or to use pins for sensors...

Also, is it possible to connect 0.96" OLED Display Module? The one that uses SCL and SDA connectors, for instance this one: https://vi.aliexpress.com/item/1005006365881525.html
