altos: Crank fast SPI on STM to 8MHz

2013-01-14T04:54:14+00:00

With the GPIO pins set to 10MHz now, we can run SPI at the maximum possible speed (8MHz). Signed-off-by: Keith Packard

altos: Set STM GPIO output speed for SPI pins correctly

2013-01-14T04:54:14+00:00

The GPIO pin settings affect the output impedence, and hence the maximum speed for SPI. Cranking these to suitable values allows SPI to run at full speed. Signed-off-by: Keith Packard

altos: Build telescience-v0.2

Update avr ao_spi_slave code to match API changes

2013-01-13T18:32:52+00:00

Made the interface use void * for pointers and uint16_t for lengths Signed-off-by: Keith Packard

altos: Initial telescience bits

2013-01-13T04:11:38+00:00

These might do something, and should at least bring up USB Signed-off-by: Keith Packard

micropeak: Record samples before boost detect

2013-01-12T17:45:31+00:00

This saves a ring of 16 samples while waiting for boost, and then goes back through those looking for the first sample higher than the ground and writes the remaining ones to the log so that we get a more complete log of the flight Signed-off-by: Keith Packard

Merge remote-tracking branch 'origin/micropeak-logging'

altos: Time out reading packet data from cc1120 after 100ms

2013-01-11T05:44:18+00:00

Sometimes the radio will give a spurious wakeup indicating that a preamble seems to have arrived, but no packet data will appear. In this case, abandon the packet reception and go back to waiting for a preamble again. This releases the SPI bus for other users and also avoids missing packets. Signed-off-by: Keith Packard

Allow CC1120 to sit on other SPI busses

2012-12-31T22:22:37+00:00

Reading the incoming data bypasses the SPI API and touches the SPI data register directly; which port that is needs to be specified in the pins file Signed-off-by: Keith Packard

altos: megadongle radio int is C13, not C14

2012-12-29T06:05:31+00:00

Hard to get interrupts when listening to the wrong pin Signed-off-by: Keith Packard
