mjb/altos/src/drivers, branch 1.4.9.1 AltOS - the operating system for Altus Metrum products https://git.ethernal.org/mjb/altos/atom?h=1.4.9.1 2014-07-05T07:38:10+00:00 altos: Rework packet receive for cc1120 2014-07-05T07:38:10+00:00 Keith Packard keithp@keithp.com 2014-07-05T07:04:06+00:00 urn:sha1:292cb8380b478542555b5f370e8252eafa2f74ac Instead of blocking on PQT, just set up the receiver to start going and when the first bit interrupt comes in, grab the SPI bus if possible and configure it for reception. This improves sensitivity in the radio by a significant amount while making the code conceptually a bit nicer.

This eliminates all floating point from TeleGPS, saving around 4kB of code space. Signed-off-by: Keith Packard <keithp@keithp.com>
