Thank you Patrick, at89c51cc03 is working fine with led blinking program. I think is a hardware problem but i dont know where. I check long time with scope to see what happen, sometimes when turn on the board, i will see good signal, sometimes not.. i measure the VCC but no spike there, is stabilized. Anyhow i try all posible, quartz, other microcontroller, other data cable, i will watch again at program, thank you for help |
