| | | | | | Includes solid fills, text and lines. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Add nvic priority register fields. Add more TIM234 defines.Keith Packard2017-02-20
| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Make i2c code handle PCLK1 of 24MHzKeith Packard2017-02-20
| | | | | | Just adds the necessary defines to the code. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Allow DMA channels to be hijacked by other codeKeith Packard2017-02-20
| | | | | | | This lets code which needs finer control over DMA to use the channel without interference, and leaves the DMA engine running so that it can. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Allow for console to be used for stdioKeith Packard2017-02-20
| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/avr: Avoid warning about unused args in stdio_put and stdio_getKeith Packard2017-02-20
| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Allow use basepri instead of primask for masking interruptsKeith Packard2017-02-20
| | | | | | | | | | | | This allows for high priority interrupts (priority 0) to run, even when other interrupts are blocked. Code executing in such interrupt handlers must not attempt to control task execution as that will race with the scheduler. Select this by defining AO_NONMASK_INTERRUPT in ao_pins.h. non-maskable interrupt priority is AO_STM_NVIC_NONMASK_PRIORITY Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Interrupt priority is in the upper bits of the priority maskKeith Packard2017-02-20
| | | | | | | | | | Because the STM32L only offers 16 priority levels, the bottom four bits of each priority mask are not used. All of the interrupt priority settings in the system were using values < 16, making them all effectively the same. Fix that by moving them into the upper 4 bits and using symbolic constants everywhere. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Don't wait while idle if trying to minimize interrupt latencyKeith Packard2017-02-20
| | | | | | | | Keeping the scanout running reasonably means keeping interrupt latency constant, and that requires leaving the CPU running. Don't wait for interrupts when the system is running in this mode. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/cc1111: Remove unneeded initialization in ao_timer.cKeith Packard2017-02-20
| | | | | | | | The timers are all stopped when the chip boots, so no need to stop them. This saves some text space, allowing the current code to (just barely) fit. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/telemini-v3.0: Swap main and apogee sense pins.Keith Packard2017-02-20
| | | | | | These were just hooked up wrong in the software. Signed-off-by: Keith Packard <keithp@keithp.com>
