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: clean up ao_exti_enable

2016-06-30T02:17:45+00:00

Was computing (1 << pin) twice for no good reason. Signed-off-by: Keith Packard

altos: Clean up -Wextra warnings

2013-12-21T06:44:04+00:00

Unused variables, mismatching signed/unsigned and a few other misc warnings. Signed-off-by: Keith Packard

altos: Add EXTI_PIN_NOCONFIGURE to exti interface, use for MS5607

2013-05-20T03:04:29+00:00

This asks the EXTI code to not mess with the pin configuration so that the MS5607 driver can get interrupts on the MISO pin while still using it for SPI. Signed-off-by: Keith Packard

altos: No need to initialize EXTI priorities at startup time

2012-08-29T06:00:22+00:00

They all get set to the correct value when enabled. Signed-off-by: Keith Packard

altos: Add ao_gpio_get and ao_exti_set_mode

2012-08-07T02:33:44+00:00

Needed to support general GPIO 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: Get cc1120 packet reception working

2012-06-25T12:03:34+00:00

Interrupt-per-bit, but it seems to work Signed-off-by: Keith Packard

altos: Fix broken EXTI edge mode selections. Clear pending exti on enable

2012-06-02T23:54:42+00:00

Make sure the edge mode registers are set according to the requested mode. Clear any pending interrupt when enabling to avoid spurious isr call Signed-off-by: Keith Packard
