altos/stm: Allow use basepri instead of primask for masking interrupts

2017-02-20T20:32:50+00:00

This allows for high priority interrupts (priority 0) to run, even when other interrupts are blocked. Code executing in such interrupt handlers must not attempt to control task execution as that will race with the scheduler. Select this by defining AO_NONMASK_INTERRUPT in ao_pins.h. non-maskable interrupt priority is AO_STM_NVIC_NONMASK_PRIORITY Signed-off-by: Keith Packard

altos/stm: Interrupt priority is in the upper bits of the priority mask

2017-02-20T20:31:16+00:00

Because the STM32L only offers 16 priority levels, the bottom four bits of each priority mask are not used. All of the interrupt priority settings in the system were using values < 16, making them all effectively the same. Fix that by moving them into the upper 4 bits and using symbolic constants everywhere. Signed-off-by: Keith Packard

altos/stm: Allow apps to define different stack size

2016-03-26T23:07:20+00:00

While 512 bytes is a reasonable size, sometimes apps don't have that much stack space. Signed-off-by: Keith Packard

altos/stm: Use flash address of boot loader instead of 0x0

2014-05-13T05:53:07+00:00

Flash is at 0x08000000, but when the chip boots, it can be at 0x0 as well. Use the 0x08000000 address when rebooting to flash Signed-off-by: Keith Packard

altos: Report battery, apogee and main voltages over APRS

2014-01-15T20:40:26+00:00

This makes APRS more usable when you mute the RF audio on the HT. Signed-off-by: Keith Packard

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
