I figured out my (brain dead) mistake. When I edited the vhdl file, I copied my block of 24 i/o definitions twice for the full 72 i/o's. So I had three encoder 00 and 01's, three pwmgen 00 and 01's, and three sets of stepgens 00-03. The pwmgen's seemed to end up on P1 of the 7i90 that I was testing, as they worked, but the encoder's ended up on P3. Quite a mess, but easily fixed. I just NullTagged the P2 and P3 banks of i/o's and reflashed. Encoder velocity works fine now.
I knew it had to be a dumb mistake :-/. Thanks for the help. -- Ralph ________________________________________ From: Peter C.

Does the state of the A input show up in hal? that is, does hm2_7i90.0.encoder.00.input-a reflect the status of the FPGA pin?
