Iura, I try to explane how it works.
The programmer have to wrte a bootloader.
The bootloader is the CDI program, but without the values.
With a PIC who can communicate over TX / RX, like the 12F628, you write only the values into the pic.
The website you show, you can communicate with a max232 or USB2TTL module.....just like we have done befor.
But, Jake have write a new program for a new pic, this pic can't doit.
