SD card reader DFR0229 + Adafruit RA8875 & TFT display Arduino help!
The DF Robot Card reader DFR229 and the RA8875 both use the SPI interface.
If I test the card reader separately it works. If I test the RA8875 + display separately it works.
If I have the SC card reader connected together with the RA8875 the card reader stops working, however the RA8875 continues working.
My RA8875 is the latest version and has the 74HC125 chip incorporated so as to release the MISO line.
Any ideas ? Help!
Thanks John
