Hello Everyone ,
I need some help. I need to set SDA pin to low for my I2C device to start.
From the GPIO pinout link mention in the documentation here [VIM3 GPIO Pinout | Khadas Documentation]. I see that pin 23 is I2C_M3_SDA but How can i identify which pin number to use in my code for I2C_M3_SDA based on this out put on android 11 ? How do i map ?
