Hi, how can I use the software SPI interface to communicate with external SPI-compatible devices ?. Like reading the output value of an ADC “MAX 11665 AUT” connected to current sensor.
The SPI of the board is connected to the Flash chip. So you cannot use it for other purpose.
You can try SPI simulation using other GPIOs.
Thank you for reply, I know that I can’t use the spi pins that’s why I am asking for how to implement a software SPI over general gpio if that is possible in the first place.
