* Use -Os for STM apps. Fix altos.ld to matchall .rodata* sectionsKeith Packard2012-03-28
| | | | | | | | Without .rodata*, it would stick the flash copy of the data on top of any further .rodata* sections. Fortunately, the linker catches that and complains... Signed-off-by: Keith Packard <keithp@keithp.com>
* Get config stuff hooked up for MegaMetrumKeith Packard2012-03-28
| | | | | | This stubs out enough stuff to let ao_config link and work Signed-off-by: Keith Packard <keithp@keithp.com>
* Add preliminary MegaMetrum v0.1 supportKeith Packard2012-03-28
| | | | | | | This turns on an LED, enables the internal R/C clock, hooks USART3 to the GPS chip and USART1 to the console. Signed-off-by: Keith Packard <keithp@keithp.com>
* Use new Makefile.defs in stm-demoKeith Packard2012-03-28
| | | | Signed-off-by: Keith Packard <keithp@keithp.com>

* Flush LCD changes each time the text is updatedKeith Packard2012-03-28
| | | | | | Rather than requiring the caller to do it. 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>
* 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>

| | | | | | | It's all very specific to the 14-segment display, so stick it there. Signed-off-by: Keith Packard <keithp@keithp.com>
* Add LCD device driver to STM32L portKeith Packard2012-03-28
| | | | | | | This enables the 6-digit 14-character display on the STM32L discovery board and provides an ascii output to it. 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>

* Save/restore PRIMASK register on Cortex-M3Keith Packard2012-03-28
| | | | | | This preserves the interrupt-enabled bit across context switches Signed-off-by: Keith Packard <keithp@keithp.com>
* Don't disable interrupts before saving interrupt flag on AVRKeith Packard2012-03-28
| | | | | | | This ignores the interrupt disabled state, so we'd always leave ao_yield with interrupts disabled. Signed-off-by: Keith Packard <keithp@keithp.com>
* Add .gitignore file to stm-bringupKeith Packard2012-03-28
| | | | | | Ignore generated binaries Signed-off-by: Keith Packard <keithp@keithp.com>
* Fix STM LED driver and blink LEDs on discovery boardKeith Packard2012-03-28
| | | | | | | | This adds a task to blink the LEDs, after first fixing up the LED output code to enable the GPIO and talk to the right pins for the discovery board. 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 AO_PANIC_STACKKeith Packard2012-03-28
| | | | | | Provide a panic code for stack overflow. Signed-off-by: Keith Packard <keithp@keithp.com>
* When debugging, send ao_panic message to ao_debug_outKeith Packard2012-03-28
| | | | | | | Use the low-level debug hooks to get the panic state sent to the serial port. Signed-off-by: Keith Packard <keithp@keithp.com>
* When debugging, send pre-init output to ao_debug_outKeith Packard2012-03-28
| | | | | | | Before tasking is running, send output to ao_debug_out to help debug system initialization. Signed-off-by: Keith Packard <keithp@keithp.com>
* Incorrect type in ao_task_info for wchanKeith Packard2012-03-28
| | | | | | Would truncate 32-bit pointers on arm. 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 bringup timers and move most of the setup code to the stm dirKeith Packard2012-03-28
| | | | 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>
* 'stdin' is a special name in some compiler environments, don't use it.Keith Packard2012-03-28
| | | | | | Switch to 'in' in the prototype for altos_serial_set_stdin. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Make sure config values are loaded in 'c s' commandKeith Packard2012-03-28
| | | | | | | | ao_config_get may not have been called when ao_config_show is invoked by the user, so make sure the config values are loaded before showing uninitialized data. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Reset config version if it's too large as wellKeith Packard2012-03-27
| | | | | | | | Any future config values will get trashed if we down grade the firmware, so we must reset the firmware version whenever it gets written. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Optimize ao_freq_to_set a bitKeith Packard2012-03-27
| | | | | | Reduces size from 327 bytes to 287 bytes Signed-off-by: Keith Packard <keithp@keithp.com>
* Do radio settings solely by frequencyKeith Packard2012-03-26
| | | | | | | Compute the radio setting needed based on the calibration value provided and the requested frequency. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Require callsign match in packet codeKeith Packard2012-03-26
| | | | | | | | | | | Ignore packets with mismatching callsigns to avoid accidental connections between devices controlled by different stations. As a special case, if the device is configured with the default callsign (N0CALL), then let anyone connect. This allows configuration of new devices without needing to change the ground station callsign. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Set correct registers for serial0 baudKeith Packard2012-01-03
| | | | | | oops. not going to work very well setting serial 1. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: flush stdout when fifo from arduino serial port is emptyKeith Packard2012-01-03
| | | | | | This avoids leaving bytes pending inside altos Signed-off-by: Keith Packard <keithp@keithp.com>
* Build teleshield by defaultKeith Packard2012-01-03
|
* altos: Add support for UART0 in async modeKeith Packard2012-01-03
| | | | | | And copy bytes from it to stdout. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: More _asm -> __asm changesKeith Packard2011-12-30
| | | | | | Missed a few last time Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Clean up for SDCC 3.1 - more keywordsKeith Packard2011-12-30
| | | | | | | | _asm -> __asm sbit -> __sbit remove variables named 'data' Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: SDCC 3.1 wants __at instead of atKeith Packard2011-12-30
| | | | | | Older SDCC would accept __at, so just replace all occurances unconditionally. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Switch teleshield to use radio slave modeKeith Packard2011-12-27
| | | | | | And bring it up at startup time by default Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add teleshield directory and bring-up codeKeith Packard2011-12-27
| | | | | | | This is cobbled together from various existing bits, but should at least provide some ability to test a teleshield board. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Create TeleMetrum v1.2 directoryKeith Packard2011-12-17
| | | | | | | The hardware is software-compatible with v1.1, but it's nice to have the right version number in all of the files. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Fix pad orientation for pre-1.1 boardsKeith Packard2011-11-13
| | | | | | | They use a different code path for accel as they don't have the VCC compensation code in place. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add startup and config (view only) pages to TTKeith Packard2011-11-12
| | | | | | The config page needs a pile of work before it's useful. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Enable packet master and debug in TTKeith Packard2011-11-12
| | | | | | The code was already getting linked in, so we might as well use it. Signed-off-by: Keith Packard <keithp@keithp.com>
