altos: Break out GPS speed resetting sequence

2012-12-04T17:45:01+00:00

To set the GPS speed, we delay for 1/2 sec, change speed, then delay for another 1/2 sec. Signed-off-by: Keith Packard

altos: Make skytraq reflashing code try both 9600 and 4800 baud

2012-12-01T04:51:47+00:00

This lets it communicate with the ROM code which boots at 4800 baud instead of 9600 baud. Signed-off-by: Keith Packard

altos: Add support for reflashing skytraq GPS chips

2012-12-01T00:10:43+00:00

This simply switches the skytraq port to 115200 baud and then essentially connects it directly to the USB port by forwarding bytes in both directions. Once started, the only way out is to reboot the board. Signed-off-by: Keith Packard

altos: Fix gcc compiler warnings in GPS code

2012-07-11T20:52:32+00:00

unused variables and mis-matches in printf format codes. Signed-off-by: Keith Packard

altos: Massive product config cleanup

2012-04-14T21:04:29+00:00

Support multiple serial ports more cleanly Split out parts of ao.h into separate feature header files Signed-off-by: Keith Packard

Allow skytraq to be on non-default serial port

2012-03-29T04:37:04+00:00

Provide ao_gps_getchar, ao_gps_putchar and ao_gps_set_speed hooks to let product specify functions for serial access. Signed-off-by: Keith Packard

altos: Trim skytraq NMEA messages. Shrink NMEA header matching code

2011-11-13T02:54:14+00:00

Tell the skytraq to not bother sending a bunch of the NMEA messages that we don't parse. Explicitly look for 'G' follows by 'P' instead of having some general header matching code. Signed-off-by: Keith Packard

altos: Make ao_xmem funcs require __xdata void * instead of casting

2011-11-12T06:30:17+00:00

Having an explicit cast in the ao_xmem wrapper macros caused the compiler to generate garbage values for pdata addresses, making the upper byte 0x00 instead of the required 0xf0. Removing the casts from the ao_xmem macros exposed this problem, so a new PDATA_TO_XDATA macros was added, along with a CODE_TO_XDATA macro which serve to cast pointers, with suitable address modifications, so that things work again.

altos: Shrink Skytraq NMEA parsing - common nmea_finish code

2011-11-12T01:18:08+00:00

This shares the checksum testing across all three lines, saving another 103 bytes. Signed-off-by: Keith Packard

altos: shrink Skytraq NMEA parsing more

2011-11-12T01:11:39+00:00

This cuts another 78 bytes Signed-off-by: Keith Packard
