I see that Microchip claims that they'll be releasing a PIC32 in a 28pin DIP package... http://www.microchip.com/wwwproducts/Devices.aspx?dDocName=en556007 It looks like only the 32k version is currently shipping (and probably isn't too interesting, given the larger images compared to AVR) (and it's not shipping in DIP yet.) But a 128K DIP-based PIC32 arduino would be an interesting beast!

(meanwhile, Freescale announced really cheap "Coldfire+" chips (no DIPS, though), and NXP says they'll put ARMs in DIPs. (rather small ones, though.)) http://www.freescale.com/webapp/sps/site/taxonomy.jsp?code=CFPLUS http://www.nxp.com/news/press-releases/2011/10/nxp-cortex-m0-microcontrollers-in-high-volume-tssop-and-so-packages-target-8-16-bit-applications.html

Interesting times.

Yeah, the 5mmx5mm 36 pin VTLA packages and the 6mmx6mm 44pin VTLA packages look really sexy...

I have my eye on the PIC32MX250F128D (VTLA)

These parts look like they only run at 40MHz, but a cursory look seems to indicate that draw less than half the current of a 80MHz device.

I've just received some PIC32MX220F032B (32K Flash, 8K RAM) samples in PDIP form factor. But not sure on what tools (programmers, compilers, IDEs) support it yet. I would love to program some C++ on this little guy.

Any recommendations where to start?

Download MPLAB and the C32 compiler from the Microchip web site. You will also need a PICkit 3 or ICD 3 for debugging and programming.

Thanks for the encouragement. That should get me to C. Next stop C++.

daverw -

Microchip just released the Microstick II yesterday - you can skip the ICD 3 / PICKit 3 and plug your DIP parts straight into it, and use it with proto boards.

The Microstick II looks pretty good but is missing USB device/host. I have an original Microstick but have never gotten around to using it past verifying it works.

I have developed my own USB device/host PIC24 development boards, and now the only thing to add looks like a crystal and caps to support USB on the PIC32.

Here is my prototype chipKIT SPDIP-28 board for PIC24 and PIC32.

Nice, it looks like there is no FTDI so I'm assuming you are planing on using the USB bootloader?

Thanks! It has an FTDI compatible cable jack on the right like some other Arduinos, so you could use an external FTDI 5V USB to TTL cable. USB bootloader would be nice too.

Thanks for the heads up on the DIP version. This completes the circle of being just as hackable as the Arduino. That is exactly how I got to using AVRs in the first place. Was because I could build an Arduino compatible on a breadboard.
