Frequently Asked Questions

Question: My d_logic board does not work. It gets very hot.
Answer: Look at the top of your board while it is powered up. Be sure that jumper J4 is inserted. A correectly finctionaing boar will have both D9 and D10 light. If D10 is light and D9 is not, likely you have a short in the 3.3V sections of the board. This can be improper wiring, scrap wire peices resting on the board, or the cPLD could have been damaged. Examine the board for wire scraps, and remove any wires plugged into the board. Retest.
