Adam's Foolish Projects
Just a place to keep links to my foolish projects.
MRI: The Monitor for Remote Inspection allows you to debug your LPC1768 based mbed device. Link your mbed executable with the mri library, attach the GNU debugger (gdb) to your mbed over the serial port, and start debugging. Supports many of the same debugging features as found in full flown JTAG debuggers: breakpoints, single stepping, variable inspection/modification, watchpoints, etc.
CrashCatcher: Library to link into your GCC compiled firmware to catch and log Hard Faults for the purpose of post-mortem debugging.
CrashDebug: Post-mortem debugging tool which can load crash logs created by CrashCatcher and make them available for debugging under the GNU debugger, GDB.
GCC4MBED: A project to allow mbed code to be compiled with GCC. It even maintains the convenience of the mbed libraries. Supports Windows, OS X, and Linux.
mbed-LPC1768 (Cortex-M3) Projects
|NeoPixelTree: An example for controlling Adafruit NeoPixels via DMA based SPI output.|
|FreqGen: Simple audio waveform generator. Uses DMA based DAC.|
|Animated Jack-O-Lantern Eyes: Bringing some life to a Halloween pumpkin with 8x8 LED matrices.|
|Green's Weather Station: Web server based weather station using Sparkfun Weather Meters.|
|SDCard: My implementation of a DMA based SDCard driver for the LPC1768.|
|mbedAdafruitLCD: A mbed port of Adafruit's 2.8" TFT LCD with Cap Touch Breakout Board w/MicroSD Socket SPI driver.|
|trackMYmbed: A mbed port of EA5HAV Javi's Trackuino (The Arduino APRS tracker).|
mbed-LPC11U24 (Cortex-M0) Projects
|Joystick as USB Mouse: Not a very useful project but fun first project with the mbed-m0 beta hardware. It uses an analog thumb stick from Sparkfun to control the absolute position of the mouse cursor on a PC.|
|Blackberry Trackball as USB Mouse: Demonstration of using the Blackberry trackball breakout board from Sparkfun and exposing it as a mouse on a PC.|
As I work on my lwip based HTTP server, I have found the need for different files systems at various stages of its development and testing. This is a list of some file systems that I have used so far.
FLASH File System: The file system image itself is appended to the program binary generated by the compiler and loaded into the FLASH of the mbed device along with the code. This allows for the remaining 512K of device FLASH to be used as a fast read-only source of file data. The read performance is >38 MB/second.
Fake File System: There are no actual files in this file system. It just allows an application to open a file of any name and pretends that all files are the same length. No actual data is read from the files but they will return EOF at the appropriate point. Useful to simulate an ultra-fast read-only source of file data.
