If you want to port the Ardupilot code or something similar, you should consider using something like these:

Maple:

This uses the stm32 arm7 processor. 90 MIPS! Is supposed to be an 'arduino' based on the stm32.

Xduino:

Yes, the ARM would be easier to start with. The LPC17xx is a great processor with the 16-bit A/D...
But, the main reason of moving in this direction
1) Memory, RAM. There is a new board coming out, with 128: of RAM, so about 30K more... the reason for more RAM is using a scripting language.... ie Lua (eLua) This will make possible to have debugging on the target. Wiring,,, is a high level that gets turned into C++, but my goal is get a stable package, drivers, basic processing loop and move to Lua for the rest....
2) Host USB, one biggest goals is to have a "pluggable" Hardware using USB.... ie off the self, wifi and USB camera's.
Yes, this is a BIG project.,... but... hope to learn as I go etc..
Also... see if openOCD JTAG will work, so have the same debugging the low level code...

Finally got gcc 4.4.x tools working with PCIC32.. Next get C++ loading, then port the Arduino and FreeRTOS...

Yikes...you're talking about writing drivers from scratch for usb hardware?

Yes/No, The first pass is to get a generic Host structure, then look at porting standard USB ethernet spec support over along with HID. Yes, this is a lot of work, but, low cost point for processor, say $40 off the self board, $40 for 1W 802.11bg usb dongle.

The goal is to have a basic framework that can be used on any ARM/MIPS small host USB. And as time allows, could do a OTG...

To make this easier just could use Microsofts open source microfamework, it already has support for host USB and I think a driver for USB etherent...

Now have OpenOCD working with UBW, next is moving to a new boot loader LUFA and new linker files etc.

Hi Tim, could you please tell me how to use CS with PIC32? Thanks.

Comment by Tim Michals on December 12, 2011 at 7:29am

I ported some of the PIC32 libraries and got most of the code running.  But, Microchip said I cannot distribute any of the code due to license issues.  So, I was going to redo this work, but said the heck with it.  I'm not please with Microchip at all for this. I got openOCD j-tag working etc.  But, I'm going for a more basic approach and use the beaglebone from TI....

Can you tell me how? Yahoo blog is not available now. If it's not convenient to say here, you can reach me at bellstudio@gmail.com  Thanks in advance.
