* altos: Make cc1120 driver return false on recv timeoutKeith Packard2013-04-30
| | | | | | Was returning an uninitialized value, which was often not zero Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Reconfigure CC1120 receiver to match our usageKeith Packard2013-04-29
| | | | | | | | Open up the AGC to the full range. Set the AGC ref based on our receive BW (100kHz). Use the previous AGC value as the first guess for the next receive. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Compute "real" RSSI value in radio code as neededKeith Packard2013-04-29
| | | | | | | | | 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 <keithp@keithp.com>

* altos: Build test framework for kalman filterKeith Packard2013-04-28
| | | | | | | This has some known flight data and generates kalman filter information for them to test Signed-off-by: Keith Packard <keithp@keithp.com>

| | | | | | Turns on pretty printing Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add nickle micropeak log parsing codeKeith Packard2013-04-28
| | | | | | I think this was just some debugging stuff, but it doesn't seem useless Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add telelco-v0.2 projectKeith Packard2013-04-28
| | | | | | Includes the necessary flash loader bits too Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Allow LCD segments to not be multiplexed across digitsKeith Packard2013-04-28
| | | | | | | This allows each LCD segment to be individually configured as to which COM and which SEG drives it, permitting maximum flexibility in wiring. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Wait after configuring boot pin before testing itKeith Packard2013-04-28
| | | | | | | | Clearly the pin isn't quite ready just after it's been configured, so hang around for a while (100 nops) to let things setting down before testing the value of the pin. Makes booting a lot more reliable. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Clear any broken cc1120 TX fifo bits before transmittingKeith Packard2013-04-28
| | | | | | | | This just goes and clears the transmitter before using it, just in case it got wedged somehow. It also clears the bits while waiting for the radio to go idle, otherwise it'd never make it. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Make cc1120 driver wait for TX finishedKeith Packard2013-04-28
| | | | | | | | | | Otherwise, we may come in and try to use the radio again too quickly, causing it to go into a TX fifo error state. This change watches the MARC status until the transmitter is explicitly marked as finished. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Provide timeout value to ao_radio_recvKeith Packard2013-04-28
| | | | | | | | | 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 <keithp@keithp.com>
* altos: Build test framework for AES codeKeith Packard2013-04-28
| | | | | | Simple CBC-CMAC test with a constant 0 key and constant 0 data for now. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Make telemega-v0.3 binary use the right nameKeith Packard2013-04-27

* altos/stm: Create per-product flash loadersKeith Packard2013-04-27
| | | | | | | Split the flash loader prototype into pieces so that each product can build a custom flash loader with very little code. Signed-off-by: Keith Packard <keithp@keithp.com>

| * altos: Make SD card driver compile without radio supportKeith Packard2013-04-25
| | | | | | | | | | | | | | | | The SD card driver blocks the radio when trying to access the card as that operation appears very sensitive to RFI. This fix makes the driver work when there *isn't* a radio driver in the same device. Signed-off-by: Keith Packard <keithp@keithp.com>
* | altos: Remove stdio from stm-flashKeith Packard2013-04-27
| | | | | | | | | | | | This saves enough memory to fit in under 4kB Signed-off-by: Keith Packard <keithp@keithp.com>
* | altos: Get rodata into flash, make sure sections are alignedKeith Packard2013-04-27
| | | | | | | | | | | | | | | | .rodata* needs to be in flash; otherwise strings get left in ram. Failing to align sections makes the initialized data get dumped into the wrong place in memory. Signed-off-by: Keith Packard <keithp@keithp.com>
* | altos: Make stm-bringup build againKeith Packard2013-04-27
| | | | | | | | | | | | stm requires AO_BOOT_LOADER_BASE now Signed-off-by: Keith Packard <keithp@keithp.com>
* | altos: Run self loader when application sets boot addr to 0Keith Packard2013-04-27
| | | | | | | | | | | | | | This causes the flash loader startup code to fall into the loader when the application sets the boot address to zero. Signed-off-by: Keith Packard <keithp@keithp.com>
* | altos: Allow STM usb driver to be used without stdioKeith Packard2013-04-27
| | | | | | | | | | | | | | This lets the self flashing loader be linked without any of the stdio code, which saves a bunch of memory. Signed-off-by: Keith Packard <keithp@keithp.com>
* | altos/stm-flash: Check target flash address against AO_BOOT_APPLICATION_BASEKeith Packard2013-04-22

* | altos/stm: Provide another 4kB of flash space for appsKeith Packard2013-04-22

* | altos/stm: Shrink stm flash loader to < 4kBKeith Packard2013-04-22

* | altos/stm: Allow core timer to be excluded from buildKeith Packard2013-04-22
| | | | | | | | | | | | | | This removes all of the support for the base 100Hz timer from the system, saving space when not needed Signed-off-by: Keith Packard <keithp@keithp.com>

* | altos: Move ao_notask to coreKeith Packard2013-04-22

* | altos/stm: Remove USB EP0 taskKeith Packard2013-04-22
| | | | | | | | | | | | | | Handl EP0 actions from interrupt handler. This allows USB to be used in a taskless environment, like the STM flash loader Signed-off-by: Keith Packard <keithp@keithp.com>
