How do you tell if you damaged the STAMP, or a problem with the LM294
on the Board of Education? I was running the MAX 7219 w/ 4 displays
just fine, now it won't work...I then hooked an LED w/ 470 ohm to the
board to see if I messed up the driver or the STAMP....The LED is
blinking, but barely visiable...any help?
