I received a reply just last week from Bojan Dobaj, author of picallw programming software for the P16pro (and other Tait-style) PIC programmers. He said that a beta release for the 18F series would be released soon. I wonder how long it will take for the info to home-build an ICD2 unit becomes available? In days gone by, I'd have bought one in a second, but I'm married now. If I can't build it from scratch, I can't afford it. 8^) Lyle ----- Original Message ----- From: "Fabio Pereira" To: Sent: Tuesday, May 07, 2002 4:41 PM Subject: [PIC]: Programming the 18Fxxx devices Hi ! Someone knows any programmer that supports the PIC 18Fxxx devices ??? I finally got my samples of the 18F452 and saw that my JDM-ICPROG can't do it. As far as I saw, the programming protocol is very different than that one of the 16 devices. The 18F devices use a four bit command followed by a 16 bit data (in/out). As I can see, the protocol works by sending PIC instructions through the ICSP interface to the target processor. Anyone knows more about it (more than it is on DS39576A) ???? I think the main problem is only on the software side (IC-PROG in my case), because the hardware (JDM) will probably work ok with the new devices. If anyone has some idea or know about a free software/programmer that supports the 18F devices, please help. Maybe we could do some efforts in building our own programmer for that (in fact I'm planning to begin with it anyway). If there is anyone interested ..
