mjb/altos/src/stm/stm32l.h, branch droid-gpsAltOS - the operating system for Altus Metrum products
https://git.ethernal.org/mjb/altos/atom?h=droid-gps2013-02-24T08:19:49+00:00altos/stm: Add more bits to NVIC register definitions2013-02-24T08:19:49+00:00Keith Packardkeithp@keithp.com2013-02-24T08:19:49+00:00urn:sha1:25435dcbc6416935aa432fc090ea977bfff5d153
This cleans up a few values, adds more comments and a few more NVIC fields.

altos: Clean up stm arch macros a bit.2012-10-25T20:38:13+00:00Keith Packardkeithp@keithp.com2012-10-25T20:38:13+00:00urn:sha1:9b978cd467f9128f3069765dd8fbf8abad3459a4
Turn a bunch of the macros into inline functions.
Clean up the reboot method to use the stm_scb structure.

altos: Add stack-guard code. Uses STM MPU to trap stack overflow.2012-10-25T07:07:14+00:00Keith Packardkeithp@keithp.com2012-10-25T05:46:55+00:00urn:sha1:4b13d3c659240e5a8347b1ba7ab0bf1d8355eba3
This marks the lowest portion of the stack as inaccessible to the CPU,
causing the processor to fault when it reaches it. The fault then
generates a panic message so that the user can know what happened.

altos: Enable STM SYSCFG when routing EXTI2012-08-29T06:00:22+00:00Keith Packardkeithp@keithp.com2012-08-28T05:45:47+00:00urn:sha1:68df2b1173e82d48f7857ad2e9325e6a9cbbedfd
The EXTI routing information is in the syscfg unit, so that needs to
be powered up or writes to its registers will be lost.

This seems better than the random loop that it replaces, but I still
have no idea why this is required; it doesn't coorespond to the docs
at all...

altos: Create a 32-bit 1MHz timer for use in profiling execution2012-06-27T06:18:44+00:00Keith Packardkeithp@keithp.com2012-06-27T06:18:44+00:00urn:sha1:fb2b83fcd28199d8c686e676d46d6ecfbf706f37
This provides a simple method for getting high-resolution timer data
to use in performance tuning code. It's not used by default anywhere.

Which GPIO a particular pin interrupt comes from is selected by the
SYSCFG EXTICR registers; set these when an exti interrupt is configured.
