Hi. I'm trying to understand the Pic32 (a decade of familiarity with Pic16 and Pic18). I got myself an Ethernet Starter Kit. The demos run, and I have been able to edit them. So I tried to get two stacks working together. I then proceeded merging the TCPIP demo and the USB MSD demo. The latter just looks for a pendrive and when it sees it a simple text file gets written. The TCPIP integ...

About a month ago, I gave a very good rundown on a new PIC32 based Micro-controller-Computer system that was about to be released. These boards arrived yesterday, and prices start at around $33. Just add a PS2 keyboard, and a VGA monitor, and you have your Micro-controller-Computer system. This is an open source hardware & software project. Olimex-DuinoMite: http://www.dontronics-shop...

Hi Well, searching the web to make a fact based decision conserning which platform would have the best performance, PIC32 or Cortex M series does not provide consistent answers. Some sites provides graphs/tables that ARM has the upper hand, and others that microchip has So, what's the deal. Any golden answer? Performance: CoreMark uA/MHz Code size Portability Etc Thanks K...

The sample thermo.zip at http://173.224.223.62/pic32 print out the pointer of a global variable. Linker place it in page A0. Microchip ran it on their simulator and they got the correct result. I ran it on the real chip and got pointer at page 7F Why, oh, why? Anyone care to give an explanation? I can lend out a test board if necessary, but right now we are short on hardware....

Integrated TFT controller in PIC MCUs

Microchip PIC32 MCUs can be used for graphics applications (as I read on their website), but I couldn't understand if they have a real integrated TFT controller (as in LPC MCUs by NXP) or a different thing. I would prefer NXP's versus Microchip's solutions for many reasons: - ubiquitous ARM core (instead of MIPS) - true integrated TFT controller - lower cost (I'm not sure on this) Bot...

Not sure how I missed this one for two months. I see there is already some serious contention with Atmel employees. http://www.eetimes.com/document.asp?doc_id=1329412 I wonder what it will be like for the sales force to be selling PICs, AVRs and ARMs all into much of the same market space? I wonder if the PIC32 will finally bite the dust with ARMs all around it crowding it out of t...

Hi So, I have been using a ST Cortex M0 STM32, NXP LPC, PIC32 and also a Renesas RX63. Just for fun. They look interesting as a potential candidate All processors has a bit to set it up in protected mode, so the flash with proprietary IP cannot be read out But, say my competitor wants to dig into my code Is there really such a thing as a safe micro controller which memory is protecte...

Select option -> Generate Code -> Build -> Build fails. Select different option -> Generate Code -> Build -> Build fails. Try yet another option -> Generate Code -> Build -> Build fails. Harmony is a giant framework where you select from hundreds of options (drivers, TCP stack, etc), then generate your application's frame. It favors a monster-loop state machine, at a point where the applica

[or the day I looked into the face of Hell. :-)] And now for something a little different. :-) What experiences have you had during debugging an embedded system that make you really wonder out loud what the hell was going on ? I've been building a homebrew programmer for the PIC32MX and have hit some major issues due to the really lousy Microchip programming specification. At one po...

Hi All - Anybody used the USB stack (thumb-drive MSD support in particular) from Microchip, with their new PIC32MX processor ? We had a bad experience with another vendor's part (specifically the provided USB stack was unworkable, and the toolchain was marginal). Any good/ bad reports and/or pointers regarding the Microchip offering would be greatly appreciated. eMail me offline if you'd rath...

Are there any mainstream 32 bit MCUs other than the MIPS based PIC32MX available in PDIP ? I'm especially interested in ARM architecture MCUs, but any 32 bit architectures are of interest; they don't need to have USB built in. When I was looking for the currently available MCUs with USB device built in, it was a major surprise to discover a 32 bit MIPS MCU range available in PDIP. I h...

Hi - Can anybody tell me for what, if anything, does GCC use the single-precision hardware floating point units on some Cortex-M4 parts? At all? Single-precision float only? Presumably not double? The PIC32MZ EF series parts have hardware double precision; presumably GCC uses this for double? Thanks! Best Regards, Dave
