LPC2148 Demo - Olimex/GCC/newlib/FreeRTOS/Fat

Posted by JC on July 9, 2007
I've put together a demo package (for lack of a better description) that runs on the Olimex LPC-P2148 board, using GCC, newlib, FreeRTOS, LPCUSB, and FatFS.

The demo shows using FreeRTOS's queues and semaphores, LPCUSB for the console via the USB port, FatFS for a FAT12/FAT16/FAT32 file system on the MMC/SD card, external interrupts, reading and writing the real-time clock, and a well-rounded newlib/syscalls.c implementation. Also included is some trivial code for parsing an attached GPS with NMEA output.

The package is available at http://jcwren.com/arm The README file in the directory is the same that is in the package. Also available is the Philips v2.2.3 flash programming utility (which seems to be less than easy to find).

For questions, comments, and pleasantly worded complaints, feel free to email me at jcwren_at_jcwren.com (yes, change the _at_ to @).

looks put together nicely. i put my examples up here. http://tech.groups.yahoo.com/group/lpc2000/files/FreeRTOS/

i have a version of almost your same demo, but with efsl instead of fatfs floating around somewhere. (freertos lpcusb efsl) no newlib though, I'm going to pay around with what you have and see how well it works.
