LM3S1968 Evaluation Kit in Linux - Conclusion
Well, that's it. I hope that was useful! I mostly wrote this just to keep some notes for myself. I struggled a little to piece together info from different sources on the net, and I wanted to put all of this together into a fairly simple intro/howto.
When I decided to use an ARM microcontroller, I looked at almost all of the current offerings from different vendors. I was looking for somthing in the $10 range that had 32-bit counters and a good set of peripherals and support software. There are a couple of things that Luminary Micro really did right that thier competitors didn't.
- Lots of good peripherals
- 32-bit timers: A lot of people only offer 16 bit timers, or kludges to build 32-bit timers from two 16bit timers... A lot of apps need 32-bits!!!
- Cheap development board: $60!! and I can use it as a JTAG dongle to debug other hardware. Other eval kits cost more, and required you to BUY a JTAG dongle (which I didn't have at the time).
- Great programming libraries.
- Full speed flash: They are the only one that I found that had full 50MHz flash... This means you don't have to move any of your program into SRAM if you have nested loops that are time critical.
- GCC toolchain works great. I can use all open source tools. This was a big seller for me.
