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

altos: Shrink STM stack size

2012-08-26T16:52:27+00:00

512 bytes should be enough for anybody. Signed-off-by: Keith Packard

altos: Place STM config values at fixed addresses for re-use

2012-07-17T08:24:52+00:00

Just like cc1111, stick the serial number and radio calibration values at known fixed addresses so that when re-flashing the board, we can go find the existing values. Signed-off-by: Keith Packard

stm: running out of memory in MM -- reduce stack to 668 bytes

2012-07-14T08:28:31+00:00

Signed-off-by: Keith Packard

altos: Increase default STM stack to 648 bytes

2012-06-28T06:09:16+00:00

512 seems cozy given the printf implementation we're using and the extensive interrupts. Signed-off-by: Keith Packard

altos: Optimize FEC encode and decode

2012-06-27T06:11:10+00:00

Integrate interleaving, CRC and padding within the decode/encode functions. Provide for ISR priorities so that the 1120 RX interrupt takes precedence over the other interrupts or we risk losing bits. Optimize the viterbi decoder a bit (goes from 10ms per packet to 7ms per packet). Signed-off-by: Keith Packard

altos: Be more careful about register save/restore in ao_yield

2012-06-17T23:14:33+00:00

Make sure the general registers are all saved before messing with any of them. Then, explicitly use r0 to save/restore apsr and primask. Signed-off-by: Keith Packard

altos: Massive product config cleanup

2012-04-14T21:04:29+00:00

Support multiple serial ports more cleanly Split out parts of ao.h into separate feature header files Signed-off-by: Keith Packard

altos: Add STM ao_arch_reboot implementation

2012-04-14T20:22:02+00:00

Uses the AIRCR register to force a reset Signed-off-by: Keith Packard

altos: Make STM clock configuration per-product. Fix 32MHz CPU speed

2012-04-10T05:17:33+00:00

This moves all of the STM clock configuration into ao_pins.h so that each product can configure it separately. While doing this, I discovered that the flash memory mode (64-bit, prefetch, latency 1) wasn't actually getting set, which is why the CPU refused to work at 32MHz. Signed-off-by: Keith Packard
