Bare metal ARM programming
I've been working with ARM Cortex based boards over the past while. One of these is the
STM32F0Discovery board from ST Microelectronics.
This is a great little board for getting to know arm based microcontrollers and it is very cheap.
Lots of the ARM Cortex documentation talks about the CMSIS specification and various board support libraries. I believe
these have their place however I have found that undergraduate engineers feel more at home twiddling bits in registers than working with a complex API. I have therefore taken a
"bare-metal" approach to programming the STM32F0Discovery board as well as other devices. Details are here:

Up to date header files
You can get updated header files for the various targets here.
Some of these updates fix bugs in the various definitions, others include additional peripheral definitions that were not in the original release.
Please feel free to mail me suggested improvements at firstname.lastname@example.org .
