altos: Crank fast SPI on STM to 8MHz

2013-01-14T04:54:14+00:00

With the GPIO pins set to 10MHz now, we can run SPI at the maximum possible speed (8MHz). 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: Leave interrupts disabled while checking for task to run

2012-10-26T21:07:04+00:00

Otherwise, we run the risk of an interrupt waking a task after we've decided to idle the CPU. 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/stm: Declare all SPI bus speeds

2012-10-15T07:06:10+00:00

Just list them all so users can pick what they like Signed-off-by: Keith Packard

altos: Allow STM SPI bus on multiple pin sets

2012-08-19T04:21:58+00:00

This allows multiple STM pin groups to be used for each SPI bus. Useful for the MS5607 sensor which signals conversion complete on the MISO line. 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

src: Add explicit 'pin' argument to ao_enable_output

2012-07-14T09:44:17+00:00

This lets the cc1111 use the atomic bit operation instead of a mask, which is immune to interrupt issues as well as being a shorter code sequence. Signed-off-by: Keith Packard

altos/stm: Expose ao_gpio_set which sets a specific GPIO pin

2012-07-14T08:28:55+00:00

Will need versions for other architectures Signed-off-by: Keith Packard

altos: include targe SPI speed in get request

2012-06-27T21:34:53+00:00

STM needs it to be provided when enabling the SPI device, so just fix AVR and cc1111 to do the same. Signed-off-by: Keith Packard
