STM Firty Too
Bought a STM32 discovery board recently. Very neat and the first board that I have had a play with that uses the two wire debugging interface. It is quite neat, the second STM32 on the board is the programming interface and it cleverly uses a USB block transfer interface to control the target STM32. I have been using the demo version of the Keil compiler and I have tweeked across quite a few of my Luminary Micro C++ classes. Quite easy really as they are both Cortex M3 based. Probably need to break down a few of classes to have a Coretex intermediate class in the heirichy. The peripheral devices aren't quite as clean as the LMS ones, things like not every I/O pin can generate an interrupt and there is no hardware FIFO on the UART but there is a DMA controller that you can do that with but it is a bit fiddlier. Will keep tweeking away and see where this takes us as I would like to make a USB <=> JTAG interface for a SHARC project I am contemplating...
