could you please give me a advise for testing after power on? especially the hardware. i want to get a efficiency method to debug hardware problem on short and open. i works on a university and support the student project. Usually, the students make the PCB by handmake, that mean easy have short or open error, i hope i can have a testing module that easy to show where is the error.
Originally, i plan to testing all 4 ports of 8052 by writing 0x55 & 0xaa, then all bits can be tested, then return the error status on P1. could anyone give me the advise?
