* altos: Wait for BT disconnect before sending commandKeith Packard2015-03-02
| | | | | | | | | | | If AltosDroid manages to connect to the BT module before we've configured it, we won't be able to talk to it as we can't force the module to ignore connection attempts. Wait for AltosDroid to give up and let us configure the device. Eventually, we'll manage, if AltosDroid's delay interval is longer than the time it takes to configure the unit.

* altos: Replace ao_alarm/ao_clear_alarm with ao_sleep_forKeith Packard2015-02-13
| | | | | | | | | | | | | | | | Having arbitrary alarms firing in the middle of complicated device logic makes no sense at all. Therefore only correct use of ao_alarm and ao_clear_alarm was around a specific ao_sleep call, with correct recovery in case the alarm fires. This patch replaces all uses of ao_alarm/ao_sleep/ao_clear_alarm with ao_sleep_for, a new function which takes the alarm timeout directly. A few cases which weren't simply calling ao_sleep have been reworked to pass the timeout value down to the place where sleep *is* being called, and having that code deal with the return correctly.

* altos/btm: Add fancier debug. Pull serial reset port low.Keith Packard2015-02-01
| | | | | | | | | | | Adds an interactive debugging mode to help diagnose BTM issues. Discovered that the serial reset pin on the BTM needs to be pulled low for the device to work correctly. Leave the bt link interrupt disabled until things are initialized. Signed-off-by: Keith Packard <keithp@keithp.com>

* altos: Do not release interrupts from any pollchar functionKeith Packard2013-03-31
| | | | | | | | | | | 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 valueKeith Packard2012-12-07
| | | | | | | | 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 <keithp@keithp.com>
* altos: Replace __critical usage with ao_arch_critical as neededKeith Packard2012-10-25
| | | | | | | | | | | | | 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.

* altos: Add the BT serial debug code back in, disabledKeith Packard2011-08-28
| | | | | | | This code is useful whenever the BT stuff is acting up, so just leave the source in place, turned off by default. Signed-off-by: Keith Packard <keithp@keithp.com>

Split out sources into separate directories: core: architecture and product independent bits cc1111: cc1111-specific code drivers: architecture independent drivers product: product-specific sources and Makefile fragments util: scripts for building stuff This should have no effect on the built products, but testing is encouraged Signed-off-by: Keith Packard <keithp@keithp.com>
