Trying to understand an USB to ICSP, I googled to find alternatives for PICKit. I found one interesting at http://usbpicprog.org/. But I was wondering why they use a PIC18F2550 and not a more simple one in the 16F range? And I was wondering if the pricipal of the program is know, so you can try to use Flowcode to program it yourself.
How can help?
Kind regards

Re: PICKit alternative?
Hi Jan,
The programmer has been created in or before 2009. At that time the 16F devices with USB were not available. Currently more USB capable devices are available, I think based on capabilities and price difference the 18F range USB devices are still a better choice at the moment. Prices for the dil package versions @ farnell:
16F1455 - 14 pin, 1K RAM, 14K flash - Euro 1,59
18F25K50 - 28 pin, 2K RAM, 32K flash - Euro 2,69
Given the size of their firmware I do not think it would fit the 14K flash in the 16F1455.
Best regards,
Jac
