altos: Use fast timer for buttons instead of edge-triggered ISR

2019-08-13T00:30:48+00:00

If the button bounces between the triggering interrupt and the button state check, we could lose the final state change of the button and send an incorrect event to the application. In the worst case, the button would end up in exactly the wrong state, toggling in the wrong direction. Use the fast timer to poll all buttons instead so that there is only one check of each button at each poll interval (instead of the interrupt and the state check). This makes buttons reliably debounced. Signed-off-by: Keith Packard

altos: Record all failed sensors and report status at power up

2019-07-16T18:12:49+00:00

Use DATA bits to mark which sensors have failed, then report that in beeps at startup time to help diagnose hardware failures while still allowing the board to be used over USB. Signed-off-by: Keith Packard

altos/micropeak-v2.0: Reduce power usage

2019-07-16T18:10:36+00:00

This gets power consumption down under 1mA on the pad. Not really low enough to sell, but I think this is about as low as the chip will go. Signed-off-by: Keith Packard

altos/stmf0: Allow SPI to be powered down when idle if desired

2019-07-16T18:09:01+00:00

Set SPI_1_POWER_MANAGE and/or SPI_2_POWER_MANAGE to have the spi blocks powered down when not in use. Signed-off-by: Keith Packard

altos/stmf0: Add 'ao_serial_shutdown'

2019-07-16T18:04:16+00:00

This powers down the UART logic on request. Signed-off-by: Keith Packard

altos/stmf0: Leave power interface disabled until needed

2019-07-16T18:02:56+00:00

We only need the power interface when placing the chip in the lowest power state, so don't power up the power interface clock at startup, instead wait until later. Signed-off-by: Keith Packard

altos: Allow ms5607 driver to either set ao_sensor_errors or panic

2019-07-15T20:26:30+00:00

Products that want to remain usable (over USB) after a sensor failure don't want to panic when the ms5607 fails, but products with limited ROM space don't want to have extra code to check for the sensor failure and panic. Change the MS5607 driver to allow either option, and then make the micropeak based devices use it. Signed-off-by: Keith Packard

altos/micropeak-v2: Update .gitignore

2019-06-19T06:18:19+00:00

Ignore built stuff Signed-off-by: Keith Packard

altos/micropeak-v2: Correct AO_LOG_ID value

2019-06-19T06:17:10+00:00

Typo wasn't caught by the compiler (thanks!) Signed-off-by: Keith Packard
