altos: Initial TeleMetrum v2.0 bits

2013-08-28T03:56:42+00:00

Adds new telemetry and logging formats along with code for TeleMetrum v2.0 design. Signed-off-by: Keith Packard

altos/stm: Create per-product flash loaders

2013-05-08T04:30:27+00:00

Split the flash loader prototype into pieces so that each product can build a custom flash loader with very little code. Signed-off-by: Keith Packard

altos/stm-flash: Check target flash address against AO_BOOT_APPLICATION_BASE

2013-05-08T04:30:26+00:00

Allows that value to change Signed-off-by: Keith Packard

altos: Use flash loader on all STM products

2013-05-08T04:30:26+00:00

Includes the boot chain stuff Signed-off-by: Keith Packard

altos: Use SYSTICK on STM32L

2013-05-08T03:08:01+00:00

It's probably more power efficient than using one of the timers, and it's certainly easier to configure. Signed-off-by: Keith Packard

altos: Make stdio 8-bit clean by making pollchar return int

2012-12-01T00:01:07+00:00

We were stealing one value (0xff) in the return value from pollchar to indicate 'not ready yet'. Instead of doing that, use the integer value -1 and have pollchar return an int instead of a char. That necessitated cleaning a few other bits to make sure that 0xff wouldn't get promoted to -1 on accident. Signed-off-by: Keith Packard

altos: Clean up stm arch macros a bit.

2012-10-25T20:38:13+00:00

Turn a bunch of the macros into inline functions. Clean up the reboot method to use the stm_scb structure. Signed-off-by: Keith Packard

altos: Replace __critical usage with ao_arch_critical as needed

2012-10-25T07:07:14+00:00

sdcc offers __critical as a machine-independent way to block interrupts, but as gcc doesn't, we need to use a compiler-independent construct instead. ao_arch_critical has been around since the AVR port, but some old __critical usages remained. This fixes a bunch of random hangs when communicating with MM over USB or the radio as the various stdio loops were running without interrupts blocked between the test and the sleep.

altos: profiling on STM32L

2012-10-25T07:07:14+00:00

Add sample-based profiling, using a 1kHz timer Signed-off-by: Keith Packard

altos: Expose a signed version of the tick count

2012-08-27T20:44:35+00:00

Useful when doing time comparisons. Signed-off-by: Keith Packard
