While we are talking about Microchip, has anyone tried using the PIC32 as a USB bus powered device in your own circuits and did you have any issues as result ? It's on my todo list in the upcoming future, so I am trying to find any possible issues upfront. I've done some searching online but I keep hitting stuff for the PIC18 or even the PIC24 instead. I have not found anything explicit ...

I got PIC32 starter kit today. Here are some impressions: - Comes with eval version of C32 C-compiler with 64KB code size limit. C32 is actually called C32-gcc, so it's a gcc derivative. The source is on the website, but who knows if it's recent or complete. - Hardware debugging (breakpoints, goto cursor) works in MPLAB on this little board, but I found that sometimes it gets int...

Hello, I am interested in many ways by MCHP's new family, as it seems to adress many of my requirements. However, this is a brand new thing (understand : "preliminary") and although MIPS has been around for ages, the PIC32 is not yet in full production. Errata and the likes will certainly come in wagons, this chips is more complex than what i have seen from this MCHP. So i turn to thi...

I've been looking at the PIC24 and PIC32 compilers from Microchip lately. These are based on the gnu toolchain. Their PIC24 compiler works for a month in a full-featured manner, and after that it goes down to a "student edition" that has most optimizations disabled. Once you pay megabucks you get them back. I initially thought this wasn't a violation because I assumed they wrote their own ...

I'm about to embark on a new project that will require a 32-bit microcontroller. I've spent the last month evaluating the merits of the various choices architecturely, and have a pretty good idea of what's out there. It's come down to development environments, and I'd like to get some first-hand reports from people on this group. The three choices on my short-list are: Pic32 and MPLAB ...


Fate of PIC32 If Microchip buys Atmel MPU business.

Not that anyone can do anything but guess what might happen, but if Microchip buys Atmel's MPU business, what is the prognosis for the PIC32. I bought some PIC32 tools and invested time learning the family, and now it may go away or new variant design activity may stop. This is because Atmel has a popular ARM based family of MPUs and the MIPS based PIC32 has only been out a year. Freescale...

Hi all, We've written an MCU-resident software development environment that we call "StickOS" that includes an editor, transparent line-by-line BASIC compiler, interactive debugger, performance profiler, and flash filesystem. We've ported it to almost a dozen MCUs (HCS08, HCS12, ColdFire, and PIC32) in the hope of making simple embedded system development easier for the casual user, and i...

Hi all, Mostly a beginner here looking for some advice. I'm trying to create an array comprised of 63 vanilla (T1) single color LEDs connected in one manner or another to a PIC32. Some of the considerations that I'm facing are that: 1. I'd like to avoid resistor arrays if possible. 2. It should be PWM dimmable. 3. It should consume as little power as possible, as it will likely share a 500...
