altos: Open up the DVGA gain to use all of the available settings

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

We usually work in RF quiet areas; let the AGC hardware try all of the available gain settings. Signed-off-by: Keith Packard

altos: Compute "real" RSSI value in radio code as needed

2013-05-08T03:07:54+00:00

Instead of dragging around the weird CC1111 RSSI values, just compute a dBm value in a signed 8-bit integer, ao_radio_rssi. Use that everywhere we need RSSI internally. We leave the weird CC1111 value in the packet reply as that's what the host expects. Signed-off-by: Keith Packard

altos: Provide timeout value to ao_radio_recv

2013-05-08T03:07:52+00:00

Instead of using ao_alarm around calls to ao_radio_recv, provide an explicit timeout value as needed by radio functions with more complicated system interaction than the cc1111. The timeout is 8 bits of clock ticks. Signed-off-by: Keith Packard

altos: Do not release interrupts from any pollchar function

2013-03-31T19:24:24+00:00

getchar relies on interrupts being blocked across the pollchar calls and into the sleep call or it may go to sleep with data pending. This prefixes all pollchar functions with _ to indicate that they are to be called with interrupts blocked and eliminates all interrupt manipulation calls from within the pollchar functions.

altos: fix functions calling pollchar to use 'int' to hold the value

2012-12-07T18:12:19+00:00

AO_READ_AGAIN doesn't fit in a char anymore now that stdio is 8-bit clean, everyone using pollchar must use an 'int' variable to capture the whole value from pollchar. Signed-off-by: Keith Packard

altos: Add support for 115200 baud serial rates

2012-12-01T00:03:45+00:00

Necessary for flashing skytraq chips Signed-off-by: Keith Packard

altos: Make stdio 8-bit clean by making pollchar return int

2012-12-01T00:01:07+00:00

We were stealing one value (0xff) in the return value from pollchar to indicate 'not ready yet'. Instead of doing that, use the integer value -1 and have pollchar return an int instead of a char. That necessitated cleaning a few other bits to make sure that 0xff wouldn't get promoted to -1 on accident. Signed-off-by: Keith Packard

altos: Share cc1111 reset/debug-start code

2012-11-30T23:10:59+00:00

These sequences are very similar, differing only in whether the dbg clock line is toggled while holding reset low for a while. Signed-off-by: Keith Packard

altos: Shrink cc1111/ao_dbg.c a bit

2012-11-30T23:05:31+00:00

Share code for osequence of ao_dbg_long_delay(); ao_dbg_send_bits() Signed-off-by: Keith Packard
