Hi all. I just soldered all the PCBs from Mike’s shop, tested all DIN’s and DOUT’s, CORE - all is working fine.
But with MBSID v3 there is a problem with interconnection test.
During the test i only can get result for cs pin which changes from 0 to +5v when appropriate key is pressed.
But no results from A0-A4 and D0-D7 #RES pins.
I thught it may be bad 74HC595, but installing new 595’s was no effect at all.
Can it be PIC problem?
All cables and other PCB solderings was checked ten times - no errors.
All power pins shows the +12 and +5 where it must been.
Any idea?
edit: after testing separately 595’s i found that all 595’s are good and working with A0-A4 and #RES, but then in other place (connected to D0-D7) is not working, and when is placed - the first 595 is not working too.
edit2: accidentally, now is working all 595’s. I think it was bad socket connection. Sometimes it need to be written about the problem, for kicking myself to solve the problem.
