PIC16F1454 Connecting To USB Doesn't Work

[rsocor01]

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...

It doesn't make any sense to me either.
