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

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

Use 16-bits for STM32 LED mask. Export serial I/O functions

Allow any STM usart to be used for stdio

2012-03-29T04:37:03+00:00

This also adds the alternate pin configurations for the other two usarts Signed-off-by: Keith Packard

Actually enable usarts with the new usart code

2012-03-29T04:37:03+00:00

And move USART1 to PB6/PB7 to avoid conflicting with the LCD pins. Signed-off-by: Keith Packard
