altos: Add Kalman filter to MicroPeak

2013-01-16T23:21:24+00:00

This filters altitudes more accurately and also allows tracking of acceleration, which is used to discard height data generated by ejection charge noise Signed-off-by: Keith Packard

altos: Make micropeak 'serial' interface work

2012-12-18T06:58:49+00:00

I prototyped the mpserial interface on a breadboard and tuned the circuit to register the LED correctly. Then adjusted the serial code to send bits at the right speed and format. The logging contents are now in hexdecimal with a CCITT CRC-16 computed to verify correct reception. Signed-off-by: Keith Packard

altos: Log baro readings for MicroPeak

2012-12-14T19:11:39+00:00

This logs barometric data every 192ms (more or less) to the 504 remaining bytes of internal EEPROM storage in the ATtiny85. This provides 48.192 seconds of logging. Signed-off-by: Keith Packard

altos: Add load-slow target for MicroPeak

2012-12-12T18:57:03+00:00

This sets the programming clock to 1/4 of the 250kHz clock used by the MicroPeak firmware, allowing the device to be reprogrammed. Signed-off-by: Keith Packard

altos/micropeak: Switch to MS5607 sensor. Require 4m for boost. Elide dead code

2012-10-29T18:47:17+00:00

Signed-off-by: Keith Packard

altos: Add initial micropeak implementation

2012-10-12T21:22:41+00:00

Blinks out max height in decimeters, stores previous flight data to internal eeprom. Signed-off-by: Keith Packard
