protofuse Posted August 16, 2009 Author Report Share Posted August 16, 2009 hi lylehazemy opto is correctly put on the problematic core!I really don't understandI'll recheck all the solders on the core to track a short circuit I didn't see...fortunately, my other core is ok.mios uploaded.my 2 DIN are ok, but my DOUT behaves strangely (i don't know if it comes from my led matrix or my dout itself: a line seems to be always on, but with a very little luminance... strange)I have to check the ain.I think I had to make my own modules PCBa big pcb with cores, ain, din, dout, double sided, with vynil coatI'm sure my problem comes from bad soldering on the one sided modules &/or wires...grrrrrrrrrrr Quote Link to comment Share on other sites More sharing options...
nILS Posted August 17, 2009 Report Share Posted August 17, 2009 You seem to have a lot of intermittent errors, proto. Earlier in the chat you mentioned that your PSU stopped working, the other core (which now mysteriously works) didn't even send out an upload request, ... Try and focus on one thing at a time.

protofuse Posted August 17, 2009 Author Report Share Posted August 17, 2009 you are right nils, but it was my first day plugged with protodeck and i just was afraid by thé beast and its behaviours ;-)so today is a cold head day... better to check without thinking to drop the whole stuff into thé sea...!i have to check further the core2. probably the short circuit that cause my psu to sleep a bit had just...killed it!the Core 1 is okupload works, etcAin & Din are ok :-)dout or code that drives it doesnt light leds matrix correctlyi'm using an uln on the first SR like noofny did.the code is : http://code.assembla.com/protodeck/subversion/nodes/protodeck/protodeck_CORE_1/main.cbut it doesnt worki suspected my matrix but it is ok after checking itfirmware has to respond to midi notes by lighting leds but in order bypass this part, i hardcoded values of ledmatrix storage table...all the same.any ideas or suggestions? http://code.assembla.com/protodeck/subversion/nodes/protodeck/protodeck_CORE_1/main.c Quote Link to comment Share on other sites More sharing options...
