Post by thread:[PIC]: 18FXX2 bootloader and availability?

According to the data sheet, the 18FXX2 series (242, 252,442 and 452) are all capable of self-programming, which I assume means that they can be programmed with a bootloader. Does anyone know where I could find a bootloader for this series PICs, or if it's just a matter of a few minor changes, how a 16F87X bootloader might be modified to work on the 18FXX2 series. Also (while I'm asking :-), I haven't been able to locate a source for these chips (or for the 18F0X0 for that matter). Any leads in this area would also be very helpful! Thanks...

Despite Microchip's claims to the contrary, the 18xxx series is not just upward compatible with the 16xxx although there is great similarity. You won't be able to just plunk a 16F87x boot loader onto a 18Fxx2, but converting one should be less work than creating a new one. On the other hand, creating a new one isn't that hard to begin with. Sometimes it's nice to start with a clean slate and you end up with exactly what you want instead of fighting with someone else's bugware all the time. > Also (while I'm asking :-), I haven't been able to locate a source > for these chips (or for the 18F0X0 for that matter).

They are in beta now, and scheduled for full availability Q1 2002. ******************************************************************** Olin Lathrop, embedded systems consultant in Littleton Massachusetts (978) 742-9014, spam_OUTolinTakeThisOuTembedinc.com, http://www.embedinc.com -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.

One of the courses at the Microchip MASTERS seminar specifically addressed the issue of bootloaders in the PIC18 series. It skimmed the class notes and they were reasonably detailed. The PowerPoint slides, etc. were on the CD-ROM given to attendees. I do not know if the CD-ROM is freely available -- you may want to contact your Microchip rep and inquire whether he can get you one. -- ______________________________________ Andrew E.

Out of curiousity, in the PIC world, what does it take to be qualified or invited to the "Masters"? Money? Exceed certain sales volumes?

Re: >Out of curiousity, in the PIC world, what does it take to be qualified or >invited to the "Masters"? Money? Exceed certain sales volumes? I believe it's open to anyone. But it's not free. This was my first MASTERS. Attending were lots of Microchip and Third Party people (both presenting and attending classes), as well as many end-users who have a vested interest in where Microchip is going, etc. It was a very nicely run event. Sales pitches are actually discouraged at the MASTERS -- it's supposed to be more of a technical pow-wow. -- ______________________________________ Andrew E.

Thanks for the response. I was wondering why it was so difficult to locate info about the 18FXX2. Has the 18F0X0 also not been released yet? That seems to be a phantom as well!

Thanks! I'll see if I can track down the CD. Ron {Quote hidden}>From: "Andrew E.
