Hi and happy holidays!
All my testing up to and thru the MEC switches (part 2 step 37) on the LE-MEC boards passed. I then added the assembled Mathias switches. Connected the boards via serial cables. No visible power anywhere in the device any longer (not measured but no LED’s come on). I removed one of the LE-MEC boards (the one with the beat led resistors) and it powers up but none of the switches (encoder, Mathias and lower MEC switches) on that LE-MEC send data though the encoder and MEC switches did prior to the Mathias installation. The encoders send data when rotated though but that’s it. When I swap the LE-MEC boards out, the other one produces the situation where no power seems to be present.
Should also add that the superflux LED’s do not illuminate on either board for what that’s worth.
Any suggestions on testing this condition?
LE-MEC Board that still allows powering up but not switches
LE-MEC Board that causes no power situation
