I'm working on a project that has a nRF2.4 radio and uses an SD card (adafruit datalogger shield). I know the card is good. I know that the code works without the SD perfectly. When I add the code for the SD card... The code just goes into a loop at "Initializing SD card... card initialized." Writing it over and over. It writes blank files to the card with no header ("millis,stamp,datetime,light,temp,vcc"), completely blank. How do I fix the dang SPI conflict!? (assuming thats what it is).
Code (Partial to void loop, which it never reaches):
