* altos: Clean up boot loader supportKeith Packard2013-03-11
| | | | | | | Split out code into separate files. Add support for getting back to boot loader from application. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add program flash functionKeith Packard2013-03-11
| | | | | | | | And get it loaded to RAM so it can execute correctly. Nothing calls it yet... Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Make stm-flash capable of switching to applicationKeith Packard2013-03-10
| | | | | | | This shrinks the base OS load down a bit as well so that stm-flash fits comfortably in the first 8kB of memory. Signed-off-by: Keith Packard <keithp@keithp.com>
* Add STM self-flashing loaderKeith Packard2013-03-10
| | | | | | | This allows the real application to get loaded at 0x2000 and jumps to that at startup time if the boot pin is set appropriately Signed-off-by: Keith Packard <keithp@keithp.com>

| * altos: Crank fast SPI on STM to 8MHzKeith Packard2013-01-13
| | | | | | | | | | | | | | With the GPIO pins set to 10MHz now, we can run SPI at the maximum possible speed (8MHz). Signed-off-by: Keith Packard <keithp@keithp.com>
| * altos: Set STM GPIO output speed for SPI pins correctlyKeith Packard2013-01-13
| | | | | | | | | | | | | | | | The GPIO pin settings affect the output impedence, and hence the maximum speed for SPI. Cranking these to suitable values allows SPI to run at full speed. Signed-off-by: Keith Packard <keithp@keithp.com>
| * altos: Initial telescience bitsKeith Packard2013-01-12
| | | | | | | | | | | | These might do something, and should at least bring up USB Signed-off-by: Keith Packard <keithp@keithp.com>
* | altos/stm: Add more bits to NVIC register definitionsKeith Packard2013-02-24
|/ | | | | | This cleans up a few values, adds more comments and a few more NVIC fields. Signed-off-by: Keith Packard <keithp@keithp.com>
* 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/stm: Support LEDs on multiple portsKeith Packard2012-11-01
| | | | | | | Split out the bits in a fairly simplistic fashion so that we support no more than 16 LEDs still. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Provide ao_task_alarm_tick to reduce per-tick costKeith Packard2012-10-26
| | | | | | | Cache the next wakeup time and check that before jumping to the task code. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Leave interrupts disabled while checking for task to runKeith Packard2012-10-26
| | | | | | | Otherwise, we run the risk of an interrupt waking a task after we've decided to idle the CPU. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Clean up stm arch macros a bit.Keith Packard2012-10-25
| | | | | | | 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 <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: Add task queues.Keith Packard2012-10-25
| | | | | | | | | This replaces the array-based scheduler with a queue-based one instead. It should have the same basic scheduling semantics, but it walks shorter lists for each operation, making it much more efficient when the system has a lot of tasks. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add stack-guard code. Uses STM MPU to trap stack overflow.Keith Packard2012-10-25
| | | | | | | | This marks the lowest portion of the stack as inaccessible to the CPU, causing the processor to fault when it reaches it. The fault then generates a panic message so that the user can know what happened. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Replace __critical usage with ao_arch_critical as neededKeith Packard2012-10-25
| | | | | | | | | | | | | sdcc offers __critical as a machine-independent way to block interrupts, but as gcc doesn't, we need to use a compiler-independent construct instead. ao_arch_critical has been around since the AVR port, but some old __critical usages remained. This fixes a bunch of random hangs when communicating with MM over USB or the radio as the various stdio loops were running without interrupts blocked between the test and the sleep. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: profiling on STM32LKeith Packard2012-10-25
| | | | | | Add sample-based profiling, using a 1kHz timer Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Force beep timer regs reload when enabling beeperKeith Packard2012-10-25
| | | | | | | Without this, there can be a long delay between asking for the beeper and having it actually start sounding. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Stop spewing clock out PA8 pinKeith Packard2012-10-21
| | | | | | | This was used to debug the clock bringup, but is not useful anymore, and probably a bad idea to boot. Signed-off-by: Keith Packard <keithp@keithp.com>
* Merge branch 'master' into mm-ms5611Keith Packard2012-10-18
|\ | | | | | | Signed-off-by: Keith Packard <keithp@keithp.com>
| * altos/stm: Declare all SPI bus speedsKeith Packard2012-10-15
| | | | | | | | | | | | Just list them all so users can pick what they like Signed-off-by: Keith Packard <keithp@keithp.com>
* | altos: Go back to recording sensor data in globalsmm-ms5611Keith Packard2012-10-08
| | | | | | | | | | | | | | | | Instead of trying to get things into the ring from a variety of functions, go back to the simpler method of storing them in globals and having the ADC code just pluck out the most recent values. Signed-off-by: Keith Packard <keithp@keithp.com>
* | altos/stm: Set SPI clock high for disabled SPI bussesKeith Packard2012-10-06
| | | | | | | | | | | | | | This should avoid an accidental low->high transition when switching between multiple SPI busses. Signed-off-by: Keith Packard <keithp@keithp.com>
* | altos/stm: Clean up SPI pin configuration codeKeith Packard2012-10-06
|/ | | | | | | Make sure none of the pin configurations are being used at startup time. Split out the pin configuration into separate functions. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Fix basic time interval to 10ms -- was 10.1msKeith Packard2012-09-09
| | | | | | Counting from 0 to 100 takes 10.1ms, so count to 99 instead. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Oops. forgot ao_data.cKeith Packard2012-08-28
| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Explicitly erase memory in STM eeprom driver.Keith Packard2012-08-28
| | | | | | This seems to make the STM32L152 happier Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Fix ao_delay function and move from per-chip code to ao_task.cKeith Packard2012-08-28
| | | | | | | ao_delay hasn't been chip-specific for a long time, and it had a bug in not calling ao_clear_alarm. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Enable STM SYSCFG when routing EXTIKeith Packard2012-08-28
| | | | | | | The EXTI routing information is in the syscfg unit, so that needs to be powered up or writes to its registers will be lost. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: No need to initialize EXTI priorities at startup timeKeith Packard2012-08-28
| | | | | | They all get set to the correct value when enabled. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Expose a signed version of the tick countKeith Packard2012-08-27
| | | | | | Useful when doing time comparisons. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Provide interface for STM LCD driver.Keith Packard2012-08-27
| | | | | | | | This provides a simple function interface for driving the LCD segments in the STM chip. It also uses the update complete interrupt to block LCD users during flush. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Trigger sample complete when all data are readyKeith Packard2012-08-26
| | | | | | | This has each sensor mark a bit in the current data record which is then sent for processing when all of the data are present. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Shrink STM stack sizeKeith Packard2012-08-26
| | | | | | 512 bytes should be enough for anybody. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Allow STM SPI bus on multiple pin setsKeith Packard2012-08-18
| | | | | | | | 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 <keithp@keithp.com>
* altos: Add button driver and event queueKeith Packard2012-08-06
| | | | | | | With this, a single task can wait for any button or quadrature input device. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add ao_gpio_get and ao_exti_set_modeKeith Packard2012-08-06
| | | | | | Needed to support general GPIO interrupts Signed-off-by: Keith Packard <keithp@keithp.com>

| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add software AES implementationKeith Packard2012-07-29
| | | | | | This is untested Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Place STM config values at fixed addresses for re-useKeith Packard2012-07-17
| | | | | | | | Just like cc1111, stick the serial number and radio calibration values at known fixed addresses so that when re-flashing the board, we can go find the existing values. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Make ao_tick_count visibleKeith Packard2012-07-16
| | | | | | | Necessary to fetch it when interrupts are already disabled as we can't call ao_time then. Signed-off-by: Keith Packard <keithp@keithp.com>
* src: Add explicit 'pin' argument to ao_enable_outputKeith Packard2012-07-14
| | | | | | | 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 <keithp@keithp.com>
* altos/stm: Expose ao_gpio_set which sets a specific GPIO pinKeith Packard2012-07-14
| | | | | | Will need versions for other architectures Signed-off-by: Keith Packard <keithp@keithp.com>
* stm: running out of memory in MM -- reduce stack to 668 bytesKeith Packard2012-07-14
| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Force STM stack to start at the top of RAMKeith Packard2012-07-14
| | | | | | | Using a fixed size means crashing if there's not enough space for that, or wasting memory if there's too much. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Increase default STM stack to 648 bytesKeith Packard2012-06-27
| | | | | | | 512 seems cozy given the printf implementation we're using and the extensive interrupts. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Clean up STM I2C clock computationsKeith Packard2012-06-27
| | | | | | Fix both clock time and rise time. Signed-off-by: Keith Packard <keithp@keithp.com>
