I recently encountered two problems when debugging 6713. I would like to ask for your experience. (1) Power-on sequence, which one should be powered on first, 3.3V or 1.2V, or should the time interval...
I disassembled a panel RJ-45 socket and found the wiring inside is very strange. It should be differential wiring, or at least it should not be coupled randomly like this (the third wire is coupled wi...
I made a board, but I didn't pay attention to connect the pin that needs to generate interrupt to the P5 port of 430. However, the P5 port doesn't seem to receive interrupts. The board is too small to...
