altos: Provide ISR-based code paths for SPI

2012-05-19T03:19:18+00:00

This allows SPI to be entirely interrupt driven, with callbacks for completion. It's not tested yet... Signed-off-by: Keith Packard

altos: Add conversion between Pa and meters

2012-05-19T03:19:01+00:00

To be used with the MS5607 which generates data in calibrated units. Signed-off-by: Keith Packard

altos: Check MS5607 CRC. Clean up MS5607 API

2012-05-19T03:19:01+00:00

It's not ready for flight yet, but at least it's sensible now. Signed-off-by: Keith Packard

altos: Conditional byte swapping in mpu6000 driver

2012-05-19T03:19:00+00:00

Only needed on LSB machines. Signed-off-by: Keith Packard

altos: Hacking at cc1120 driver

2012-05-08T04:52:12+00:00

Still doesn't work, but this adds a ton more register definitions Signed-off-by: Keith Packard

altos: Get mpu6000 working

2012-05-08T04:51:25+00:00

This initializes the device appropraitely, and provides a command to dump the current values in converted form. Signed-off-by: Keith Packard

altos: stm: pass DMA buffer index to DMA completion callback

2012-05-08T04:50:26+00:00

This lets the user know which DMA has finished. Signed-off-by: Keith Packard

altos: stm: delay during USB config with pull-up off

2012-05-08T04:49:24+00:00

This makes sure that a reboot will reliably cause the device to disconnect from the USB bus. Signed-off-by: Keith Packard

altos: stm: share i2c_stop code between send and recv

2012-05-08T04:47:17+00:00

This waits for the stop signal to appear on the bus, necessary before starting another transaction. Signed-off-by: Keith Packard

altos: stm i2c DMA for large recv appears to work

2012-05-07T06:54:13+00:00

Transaction appears to be clean on the i2c bus now; correct number of bytes received, and the nack and stop at the right time. This tests > 2 length reads; should try that too. Signed-off-by: Keith Packard
