i already made 2 gman pms, no issue about them, they work very well, but when i program third pms, troubles came, i already sufferred 3 days for troubleshooting, and killed 4 pic16, including the two on the good pms board, when programming, sometimes it showed format %x on screen, and warning debug bit is set on taget image, the light on the pms board did not turns on. I try to program new pic16 on empty board,it is still same problem, i wanna konw what i can do to confirm the pic16 is dead, because the new pic16 have the same issue, any advise will be appreciated
remark:picture upload ,i test the new pic16 on the good working pms, it did not work. and simutanously, i test the good-programming pic16 on anothor non-working pms board, it did not work either, more frustrated thing happened when i soldered the good-programming pic16 on the original pms board, it was fucking dead,even though i can program to the before-good-proramming pic16 as shown on pictrure,the lights never turn on and it stop working. Then I check both two pms boards, the output votage from the power supply ic is 4.2 v when powering pms from charge pin, it is normal,and no short on all the capacitors
thanks,god, i have no choice, so relocate all parts to a empty board, programming pic16 again, lights fucking turn on cheers
