Post by thread:Problems with PIC-1 programmer

Hello Piclisters, I have just received the ITU Pic-1 programmer. After having assembled it, I tried to follow the "Test & Use" section on Pg.8 of the manual. However, after connecting the DB-25 cable to the PC and the programmer's connector and applying 16volts AC, both the "Power led" and the "Program led" are illuminated ,with the PIC16F84 out of circuit. I notice that the " program led" should only come on during programming. Could you offer any explanation for this and a possible solution to this problem. All other voltages are correct.

This is normal. The program LED will go out when the ITU software initalizes the parallel port. I allways start the software with the programmer hooked up and no chip in. Then I try to program or erase a chip without the chip in. The programmer gives an error but clears the program LED. I don't think it really hurts to be on but it bugs me so I clear it first.

The same thing happens to mine. I've found that this usually occurs right after power up. Once you initialize the programmer (i.e. run the programming SW... I use pic12cp.exe) the programming light turns off when you are prompted to insert the PIC. I meant to send an e-mail to ITU requesting them to document this, but I haven't gotten around to it.
