Ozipic'er p16pro40 problem

74HC14:

Pin 2 = 5.33V
Pin 4 = 5.30V
Pin 5 = 0.74V
Pin 8 = 5.27V
Pin 10 = 0.76V
Pin 12 0.74V

You need to toggle the pins and see that they change correctly.

Well I toggleled the pins high/low on/off but voltage never changed, always stays the same.

2 = 5.87V
4 = 5.86V
5 = 0.76V
8 = 5.9V
10 = 0.77V
12 = 0.768V

Check the pins of the buffer chip that go to the parallel port, and ensure that those change OK.

I have changed a faulty component on the board and now the LEDs switch on/off according to WinPicProg, but it still doesn't detect it. I tried to program it but the program gives me an error after verifying.

 

[Nigel Goodwin]

The auto-detect works like this:

1) Select the first port address.

2) Set Vdd ON

3) Toggle Data (D0) up and down.

3) Check for the same returned data on the Ack pin.

4) Select second possible address and do the test again.

You can easily do this manually, and check that the Ack line changes with Data out (it's even indicated on the WinPicProg manual toggling screen).

I tried with my windows 98 old pc and it didn't detect it, but with my windows 7 (5 year old pc) detected it but didn't program correctly, with another pc (win xp) it didn't detect it with winpicprog but programmed it with icprog.

I managed to program it with my windows 7 pc also.

How did you get the driver DLL working on Win7?, as far as I'm aware it doesn't work after XP - but can't try it as I don't have any PC's with parallel ports any more.

 

[Sahbin]

I don't know I downloaded Icprog NT/2000 driver file, launched icprog and it programmed it without problem.

Thank you very much for you help I couldn't fix it alone
