PIC16F1454 Connecting To USB Doesn't Work

Great, the only post I found over at MeLabs has a reply from Darrel explaining the 16F145x are mutant PICs. [/url]

Darrel had a special talent to understand things when they were difficult and not obvious. I learned a lot from his posts.

I'll ask and see what happens.

I will send Melabs an email. They always respond to my technical questions. I'll keep you posted.

Hmm, I'm trying to make this chip work with just an LED and the chip is not cooperating. I'm getting a "Does not match target device" error. When I try to get the target information, I get a different target id than the one in the INC file. If I change the INC file id to 3FFF, it doesn't work either.

I'm using the programming pins 9 and 10 to program the chip. The other 2 pins, 12 and 13, are for low voltage programming. They don't work either if I try them.

Is there anything of value over there:

Are you using the ZIF adapter?

And check out post 4 about the epic programmer files.

(I see you have EPC in you image.)

Hmm, I made it work for a flashing LED. This is weird, you need to power the 16F1454 chip with 5V. It won't get programmed if I power it with 3V. I have never seen this for a regular 16F chip.

Yes, that post from the forum was very helpful. He had some issues programming the chip too.

Like I said, mutant PICs.

Why Microchip do such stupid things, like two sets of programming pins for low or high voltage?

Oh dear...
