altos: Replace ao_alarm/ao_clear_alarm with ao_sleep_for

2015-02-14T07:51:10+00:00

Having arbitrary alarms firing in the middle of complicated device logic makes no sense at all. Therefore only correct use of ao_alarm and ao_clear_alarm was around a specific ao_sleep call, with correct recovery in case the alarm fires. This patch replaces all uses of ao_alarm/ao_sleep/ao_clear_alarm with ao_sleep_for, a new function which takes the alarm timeout directly. A few cases which weren't simply calling ao_sleep have been reworked to pass the timeout value down to the place where sleep *is* being called, and having that code deal with the return correctly.

altos/stm: Add ability to delay STDIO usage for serial ports

2015-02-01T15:36:51+00:00

Bluetooth needs to delay adding the serial port to stdio until the link is up and running. The cc1111 serial driver had DELAY_SERIAL_*_STDIN bits which have been added to the STM serial driver. Signed-off-by: Keith Packard

altos: Add support for TeleBT v3.0

2015-01-24T19:18:59+00:00

Add support to the BTM driver for non-CC1111 interrupts Add HW flow control to STM serial driver Signed-off-by: Keith Packard

altos: Do not release interrupts from any pollchar function

2013-03-31T19:24:24+00:00

getchar relies on interrupts being blocked across the pollchar calls and into the sleep call or it may go to sleep with data pending. This prefixes all pollchar functions with _ to indicate that they are to be called with interrupts blocked and eliminates all interrupt manipulation calls from within the pollchar functions.

altos: Add support for 115200 baud serial rates

Necessary for flashing skytraq chips 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: Switch drivers to ao_arch_block/release_interrupts

2012-10-25T18:25:42+00:00

Stop using cli/sei, which are avr-specific 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: 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

altos: Oops. Set per-USART STM baud rate register instead of usart1

2012-04-03T02:29:21+00:00

Was accidentally always setting usart1 instead of the per-usart register. Didn't work too well for other usarts... Signed-off-by: Keith Packard
