today i bought a 20MHz crystal for my PIC16F877. it has a big body and three terminals. the third terminal is connected to the body of the crystal. ive read somewhere that this helps reduce EMI. should i connect this to the ground or not. i mean is there any need for such measures. i dont think there would be much EMI generated by just flashing a bit of LEDs :lol:
