* altos/stm32l: Add support for software-driven HW flow controlKeith Packard2016-04-25
| | | | | | | | This allows applications to request that the flow control bits be driven from software rather than hardware, permitting more flexible pin configuration. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Use TXE instead of TC for serial on STM32lKeith Packard2016-04-25
| | | | | | | Using TXE allows for full-speed communication, rather than waiting for each byte to be transmitted before inserting the next into the queue. Signed-off-by: Keith Packard <keithp@keithp.com>

* altos: Replace ao_alarm/ao_clear_alarm with ao_sleep_forKeith Packard2015-02-13
| | | | | | | | | | | | | | | | 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 portsKeith Packard2015-02-01
| | | | | | | | 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 <keithp@keithp.com>
* altos: Add support for TeleBT v3.0Keith Packard2015-01-24
| | | | | | | Add support to the BTM driver for non-CC1111 interrupts Add HW flow control to STM serial driver Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Do not release interrupts from any pollchar functionKeith Packard2013-03-31
| | | | | | | | | | | 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 ratesKeith Packard2012-11-30
| | | | | | Necessary for flashing skytraq chips Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Make stdio 8-bit clean by making pollchar return intKeith Packard2012-11-30
| | | | | | | | | | 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 <keithp@keithp.com>
* altos: Switch drivers to ao_arch_block/release_interruptsKeith Packard2012-10-25
| | | | | | Stop using cli/sei, which are avr-specific Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Massive product config cleanupKeith Packard2012-04-14
| | | | | | | | Support multiple serial ports more cleanly Split out parts of ao.h into separate feature header files Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Make STM clock configuration per-product. Fix 32MHz CPU speedKeith Packard2012-04-09
| | | | | | | | | | 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.

* altos: Oops. Set per-USART STM baud rate register instead of usart1Keith Packard2012-04-02
| | | | | | | Was accidentally always setting usart1 instead of the per-usart register. Didn't work too well for other usarts... Signed-off-by: Keith Packard <keithp@keithp.com>
* Use 16-bits for STM32 LED mask. Export serial I/O functionsKeith Packard2012-03-28

* Allow any STM usart to be used for stdioKeith Packard2012-03-28
| | | | | | | This also adds the alternate pin configurations for the other two usarts Signed-off-by: Keith Packard <keithp@keithp.com>
* Actually enable usarts with the new usart codeKeith Packard2012-03-28
| | | | | | | And move USART1 to PB6/PB7 to avoid conflicting with the LCD pins. Signed-off-by: Keith Packard <keithp@keithp.com>

* Add STM platform and stm-bringup demo programKeith Packard2012-03-28
The stm-bringup doesn't run altos, it just initializes the device and writes stuff over a serial port. Works on the STM32L Discovery board at least, should do stuff on other boards too. Signed-off-by: Keith Packard <keithp@keithp.com>
