I've started work on a new robot controller based on the Netburner MOD5213. After lots of searching I settled on the Netburner controller for a few reasons:
- Price for the performance is outstanding. The module is only $39 and sports a 32-bit Coldfire processor with lots of hardware peripherals.
- Development Support. The dev kit includes a controller, board and complete C/C++ compiler and IDE for $99.
- Lib support. The dev kit includes the uC/OS RTOS, libs for interrupt driven SCI, A/D and GPIO support.
There are some issues that will have to be overcome:
- The controller is NOT 5 volt tolerant so a scheme for interfacing 5v sensors will need to be developed (optoisolators or a simple voltage divider come to mind).
- The dev board does not have ready made connectors for external hardware. I have started working on a daughter card that will plug into the dev board to address this.
I plan on documenting the process extensively, and will try and keep this blog up-to-date for those who want to track the progress. I also welcome and comments or questions since it can only help improve the overall design and execution.
