I use the Arduino Due. I set up the connections of the SD card to pin 9 and a touch screen to pin 10 both get the MISO, MOSI & TCK from the same pins (74,75,76). Now the internal setup of the Arduino Due is configured in a way to normally just use pin 4 and 10 as chip select pins for SPI. However, is it possible to those via software based SPI control?
Or rephrasing the question. Is it possible while using the extended SPI to use other pins then 4, 10 and 52 to connect an SD cart with the Arduino ´Due?
