altos: avr-gcc appears to find the loader scripts without help now

2013-10-08T16:50:21+00:00

At some point, avr-gcc lost its ability to find the loader scripts necessary to link programs. That appears to be fixed now, at least on my machine. Signed-off-by: Keith Packard

Add --with parameters to configure for compiler selection

2013-10-08T16:22:03+00:00

This allows the user to specify which compiler to use for each target CPU. Also checks to make sure the arm compiler supports -m0 and -m3 cpu type flags. The build now actually uses the specified compilers too. Signed-off-by: Keith Packard

altos: Move micropeak sources around

2013-09-15T21:11:50+00:00

This sticks the micropeak sources in appropriate directories, rather than in the micropeak product directory so that they can be shared with future micropeak-style products. Signed-off-by: Keith Packard

altos: Explicitly list the linker script needed for AVR targets.

2013-08-26T05:22:55+00:00

Something changed in the binutils-avr package which makes the linker fail to find the script in the default location. Signed-off-by: Keith Packard

altos: Move ao_notask to core

2013-05-08T03:16:53+00:00

The STM flash loader wants to be taskless too, share this very simple implementation of sleep/wakeup. Signed-off-by: Keith Packard

altos: Add nickle micropeak log parsing code

2013-05-08T03:07:53+00:00

I think this was just some debugging stuff, but it doesn't seem useless Signed-off-by: Keith Packard

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

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

altos: Add distinct LED pattern before writing log data

2012-12-18T08:39:37+00:00

Otherwise, the whole log looks like a an extra altitude digit. 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
