We designed our own carrier board to work with B01 module. There is a switch chip REALTEK TL8367N-VB-CG on carrier board. We use I2C0 to communicate with it. However, the I2C of TL8367N-VB-CG is not standard, B01 can’t find the device.
Can I2C0 config as GPIO？ We want to use GPIO to simulate the timing. THANKS!
