* altos: Add Kalman filter to MicroPeakKeith Packard2013-01-16
| | | | | | | | 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 <keithp@keithp.com>
* altos: Make micropeak 'serial' interface workKeith Packard2012-12-17
| | | | | | | | | | | 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.

* altos: Log baro readings for MicroPeakKeith Packard2012-12-14
| | | | | | | | 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 <keithp@keithp.com>
* altos: Add load-slow target for MicroPeakKeith Packard2012-12-12
| | | | | | | 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 <keithp@keithp.com>
* altos/micropeak: Switch to MS5607 sensor. Require 4m for boost. Elide dead codeKeith Packard2012-10-29

* altos: Add initial micropeak implementationKeith Packard2012-10-12
Blinks out max height in decimeters, stores previous flight data to internal eeprom. Signed-off-by: Keith Packard <keithp@keithp.com>
