First time getting into Arduino this week. Trying to get a sumotoy TFT_ILI9163 working inconjunction with PN532 NFC. I am able to get both working fine using example projects over SPI. Each has a separate CS pin so hardware wise I think it all is good.
To simplify I tried adding TFT print functions to the standard Mifare NFC example. But only the device that I put first. ie nfc.begin() or tft.begin will work. It then seems to lock up, I assume that the first one is grabbing the SPI via its CS and not letting go. I couldn’t find any information about whether you need to manually toggle the CS for these drivers in between statements.
Unfortunately I don’t have an oscilloscope yet to analyse how the CS lines trigger for the drivers.
Thanks for any advice
