zachtheterrible said:I have the p16pro40 breadboarded and I've checked the whole circuit over about 3 times. Everything is perfect! I can't get anything to happen though.
The two red LEDs are on and the green one is not. Nothing changes when I start the Winpicprog on my computer. I'm using my regulated power supply that is currently putting out 17.7V, I can change that voltage if needed. The powersupply says that the circuit is consuming about 80mA.
Whenever I start the programmer it says Port: none. Which obviously means it's not seeing my programmer.
Am I supposed to do something with the DLportIO program?
Very lost here, if someone could help me troubleshoot I'd be very grateful :lol:
EDIT: When I turned my PSU off and on, the green LED came back on, so all the LEDs are on now.

If you made it yourself, then it is most likely incompatible with the program.
zachtheterrible said:Funny, now only one red LED is on, and the other red one comes on whenever i unplug the cable. The green doesn't want to come on.
I'm using a 7406 and I set the hardware settings to that.
Nigel, what do you mean by all the external operations are disabled?
I wish I knew more about this. I'll check everything with a voltmeter when I get some time.
Oh yeah, and should I have auto program selected?
zachtheterrible said:Yes, the read and write buttons are disabled.
I'm beginning to think that the problem has nothing to do with my programmer. The reason I say this is that in the hardware settings, if I chang stuff around and turn things on/off high/low, I can't get the state of any of the 3 LEDs to change.
One of the red LEDs will turn on when I reboot the computer, but when I open winpicprog, it turns off.
zachtheterrible said:Alright, I'm excited to say that I did get somewhere. I got the two red LEDs to flash. I found out that my port is $378.
It still won't recognize my programmer. Do I have to have a PIC in the programmer in order for winpicpro to recognize it?
Also, I don't get how pressing the vdd toggle button will turn the green LED on and off. On the schematic, the green LED is wired straight from vpp to ground. Also, when the two red LEDs are on, the green one turns off. I guess this is because there is insufficient current to feed them all?
I also tested the voltages on the port and got each pin to change voltage by toggling the buttons.
One thing I'm a bit conerned about is this: Whenever I restart the program and go to the hardware page, it is on the wrong port address. I'm wondering if this is having something to do with it?
zachtheterrible said:I hope it's an easy fault to find because I did what you said and it didn't work Nigel.
I even rebuilt the entire circuit with the same results.
Is there a possibility that I could've wrecked the buffer somehow? I was reading someone's page on the p16pro40 on the net and they said not to turn the computer off with the programmer on. I've done that numerous times.

Try this:
Set to the correct address.
Turn Vdd ON.
Toggle the Data Output line - the Data Input line should follow suit, if it doesn't you have a fault somewhere, which should be easy to fault find.

Nigel, I did exactly that and it did not work. The output of the p16pro40 DOES follow suite when I watch it with a voltmeter. It doesn't show up on winpicprog though.
I have also checked everything with a voltmeter to see if it's working and everything toggles when I switch it on the hardware window. That also leads me to believe that my buffers are fine as well.
I'm sure that my parallel port is fine because I have a laser printer hooked up to it when I'm not trying to program and the printer works perfectly.
