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: 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: Replace __critical usage with ao_arch_critical as needed

2012-10-25T07:07:14+00:00

sdcc offers __critical as a machine-independent way to block interrupts, but as gcc doesn't, we need to use a compiler-independent construct instead. ao_arch_critical has been around since the AVR port, but some old __critical usages remained. This fixes a bunch of random hangs when communicating with MM over USB or the radio as the various stdio loops were running without interrupts blocked between the test and the sleep.

Report RSSI values in monitor idle UI (trac #44)

2012-07-11T20:53:30+00:00

This adds a new 's' command to TeleDongle to report RSSI value from last received packet, and then has AltosUI request that value when closing the remote link. Signed-off-by: Keith Packard

altos: Starting to write cc1120 driver

2012-04-17T18:01:18+00:00

This does "something" in radio test mode, appearing to generate a 730MHz signal. Signed-off-by: Keith Packard
