OK - I got the new LED&Key board and the one I received this time was clearly made better than the last two - even though I got them from the same source. Odd. I also replaced the voltage regulator successfully. I have everything in the enclosure and it powers up fine to the Clough boot screen but I am getting nothing from my encoder as RPM on the display. Consequently, the servo does not spin of course. I tested the encoder with an ohmmeter (black/blue, blue/white) and they read the same so I am pretty sure the encoder is OK. I flipped the switches back and forth a few times to make sure they were set correctly on the TI board.
I also tried both of the encoder connections EQEP 1 and 2 (and reflashed the code accordingly) same result. I do not have an oscilloscope to do more detailed tests on the board, but in reading a closed post here on github from another user it may be the TI board (again). Are there any good tests that can be done without a scope? If there is a bad resistor can I just get one and solder it onto the board rather than buying a whole new board?
Also, on a side note, I used a laser thermometer to look at the temps on the boost board just to see what was going on there. The only thing that stood out to me were resistors R7 and R8 which seemed warmer than the rest heating up to ~125F pretty quickly. Not sure if this means anything but it is a data point.
Thanks
