hi everyone , I have programmed pic 18f4431 successfully . I bought a new breadboard ,but not a good one. after measuring the power on MCLR ,i found the power was too litle. (a bad Breadboard) After programming with my old breadboard ,everyting was ok. Thanks everyone for suggestions and help Jos Op maandag 6 november 2023 om 23:07:11 UTC+1 schreef Zet Weeh:
