#106767 - Loop appear to be random at the beginnin Responding to: ???'s previous message |
Thank you. But I got another problem. My problem is to repeat a loop again and again. Sometimes when I power it on and reset, the sequence does not go in the correct way at the beginning (sometimes it's random and the situation is obvious if I let the power off for a longer time and on again), and it will only follow the program after starting for a while (about 1-2 cycle of the program main loop). Will there be possibility of things affecting the chip from outside? It seems that if I don't connect the fan, the situation does not occur.
Also, when I run the compare function of the chip, it's found that the data in address 00h is different (device value 00h, buffer value 75h), will there be possibility that I program it wrongly? I am using the Dataman 48LV PC Universal Programmer. I use Medwin to convert the asm file to bin and then the Dataman software to auto program the AT89C2051. Thank you for your help! |
