I built three of Joe's A3977 board from pminmo's site.
When I apply power, I get absolutely no response from the 3977. The LED lights, the hex trigger appears to be working correctly, and the voltages on each of the input pins are as expected. But there are no outputs.

Any suggestions?

I answer questions related to the boards on my website at my BB: http://www.pminmo.com/phpBB/ Nothing against the zone, but on my site it's a collection place for others to benifit from the same focused Q & A. The zone is so big, you can answer the same question 10 times, and not find any of the answers.
