* altos/stm: Use #define'd constants for GPIO register addressesKeith Packard2014-05-12
| | | | | | | This lets the compiler short-circuit the tests in ao_enable_gpio and ao_disable_gpio to save a bit of code space and time. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Figure out available flash space based on chip id registersKeith Packard2014-05-12
| | | | | | | Look at the flash size and the device id registers to figure out how much flash is available. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Clean up -Wextra warningsKeith Packard2013-12-20
| | | | | | | Unused variables, mismatching signed/unsigned and a few other misc warnings. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Initial TeleMetrum v2.0 bitsKeith Packard2013-08-27
| | | | | | | Adds new telemetry and logging formats along with code for TeleMetrum v2.0 design. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add fast-timer API. Use for quadrature and button driversKeith Packard2013-06-09
| | | | | | | This splits the fast-timer portion out of the debounce helper code and shares that with the quadrature driver which now uses it directly. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add program flash functionKeith Packard2013-05-07
| | | | | | | | And get it loaded to RAM so it can execute correctly. Nothing calls it yet... Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Use SYSTICK on STM32LKeith Packard2013-05-07
| | | | | | | It's probably more power efficient than using one of the timers, and it's certainly easier to configure. 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: 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: 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: profiling on STM32LKeith Packard2012-10-25
| | | | | | Add sample-based profiling, using a 1kHz timer 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: 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>
* altos: Add driver for STM internal flashKeith Packard2012-07-29
| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Wait for i2c START condition before setting interrupt bitsKeith Packard2012-06-27
| | | | | | | | This seems better than the random loop that it replaces, but I still have no idea why this is required; it doesn't coorespond to the docs at all... Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Create a 32-bit 1MHz timer for use in profiling executionKeith Packard2012-06-26
| | | | | | | This provides a simple method for getting high-resolution timer data to use in performance tuning code. It's not used by default anywhere. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Route correct GPIO line to interrupt controllerKeith Packard2012-06-02
| | | | | | | Which GPIO a particular pin interrupt comes from is selected by the SYSCFG EXTICR registers; set these when an exti interrupt is configured. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Oopsed the STM DMA channels for I2C1Keith Packard2012-04-25
| | | | | | TX is 6, RX is 7 Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Starting to write cc1120 driverKeith Packard2012-04-17
| | | | | | | This does "something" in radio test mode, appearing to generate a 730MHz signal. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add register definitions for STM syscfg and usbKeith Packard2012-04-14
| | | | 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: Add beeper driver to STM archKeith Packard2012-04-09
| | | | | | Drives the MegaMetrum beeper Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: add STM I2C driver.Keith Packard2012-04-09
| | | | | | Not well tested yet... Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add STM temperature sensor calibration dataKeith Packard2012-04-07
| | | | | | | Each stm32l has two-point factory temperature calibration data. Provide access to that for displaying temperature data. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add support for STM ADCKeith Packard2012-04-07
| | | | | | DMA-based driver for the STM analog to digital converter. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Declare stm DMA address registers as volatile void *Keith Packard2012-04-06
| | | | | | Eliminates a cast when assigning to them. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add DMA, SPI and MS5607 driversKeith Packard2012-04-06
| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* Automatically set ALTERNATE pin mode when setting alternate functionKeith Packard2012-03-28
| | | | | | | When selecting an alternate function, set the pin to alternate mode as well; there's no sense requiring two separate calls everywhere. Signed-off-by: Keith Packard <keithp@keithp.com>
* Add defines for LCD controller and RTC clockingKeith Packard2012-03-28
| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* Add support for multiple serial ports on STM32LKeith Packard2012-03-28
| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* Basic OS running on STM32LKeith Packard2012-03-28
| | | | | | This gets stm-demo working Signed-off-by: Keith Packard <keithp@keithp.com>
* Add stm-demo programKeith Packard2012-03-28
| | | | | | This runs AltOS and talks over the serial port. 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>
