Those chips are the cheapest 18F with USB according to the Microchip Advanced Selector Chip tool. I'll order some and give it a try.
I just hit a sweet deal. At that price, I cleaned out everything they had on hand: 9860 These go for $3.91 / 100 at Digikey.
The good news is that the 18F25K50 isn't that expensive. I'll order some and I'll give it a try. 9859
Bad news, I got this response from Melabs. We tried many years ago, but failed to make the USB commands work in a useful way. In any case there is no further development planned for PBP. ...
It doesn't make any sense to me either.
Why Microchip do such stupid things, like two sets of programming pins for low or high voltage? Oh dear... Ioannis
Like I said, mutant PICs. 😁
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. ...
And check out post 4 about the epic programmer files. (I see you have EPC in you image.)
Is there anything of value over there: https://support.melabs.com/forum/device-programmers/u2-usb-programmer/711-16f1455-support-on-older-usb-programmer#post2077 Are you using the ZIF...
