I bet some day we have needed to or wanted to save a large amount of data using the common SD cards and some microcontroller.For example to save samples of temperature every hour, or every minute, to read pictures and show them in a full color display, or maybe to make an mp3 player. Well the possibilities are huge.
This time I wanted to save EMG signals (Electromyography) from my active EMG sensors. For this reason I made a circuit and a program for the PIC18F2550 microcontroller.
Basically I have to meet two requirements.
