Hello,
I have a simple populated PCB with passive and active elements. The main chip on PCB is a 8 pin serial EEPROM chip which I am trying to read via PIC microcontroller. Serial chip is tiny and hard to solder wires onto so I can send signals from PIC controller to the chip. I will have easier access via traces onto other elements on the board. I am running continuity test to trace pins to other elements but I get beeps on multimeter that seem to suggest incorrect wiring. I doubt my continuity test technique because it is a commercial PCB. What techniques I can use to ensure I am using the correct pin mappings?
Thank you
