Team Plastics Separation / Mbed 2 deprecated ECE4012-PHD_data_out_and_1pps

Added functionality to output stored data to sd card. Code for SPI communication to modular sensor array is commented out due to bugs in reading in SPI data from arduino. (Sending SPI data to arduino is working)

Dependencies:   Regrind RioRandHBridge SDFileSystem Solenoid mbed

Fork of ECE4012-PHD by Mitchell Pang
