I am a newbie to use the teensy board, so please forgive me if I ask some stupid questions.
I moved my project from Arduino Mega to Teensy 3.5. Because of the design limitation, I cannot use the built-in SD card slot. I would like to use external SD card adaptor to connect with Teensy 3.5 via SPI connection. The problem is when I use SD.h or SDFAT.h libarary for the card info sketch, I cannot even access to the card, always ask me if the wiring is correct. The card works fine on build-in SD card slot with Teensy 3.5 and works fine on Arduino Mega or Teensy 3.2 with SPI connection.
I think I need to change something on Sdfat or SD library to make it work. How can I change the library to make the SD card working with SPI connection on Teensy 3.5?
Any advices will be helpful, thanks!
