* altos: Handle internal and external telem monitoring requestsKeith Packard2011-11-12
| | | | | | | | | | | | Record separate internal vs external monitoring state, allowing both to happen at the same time, and when either is turned off, the other keeps working. This also adds disable/enable so that other radio users can temporarily take over the radio; monitoring will resume when the other radio user is finished.

* altos: Check pdata+xdata memory usage during buildKeith Packard2011-11-12
| | | | | | | | | | | The sdcc linker doesn't check the sum of pdata+xdata memory usage, it only ensures that xdata itself is small enough. This doesn't keep xdata below the end of usable ram on the cc1111 though (0xfe000). Fix up the check-stack program to also make sure all of xdata fits in available memory.

* altos: Make ao_xmem funcs require __xdata void * instead of castingKeith Packard2011-11-11
| | | | | | | | | | | | 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/avr: SPI mutex is now held by the caller, not the SPI driverKeith Packard2011-10-11
| | | | | | | | | SPI transactions generally require a read followed by a write, with the chip select held the whole time. As a result, the SPI bus must be held across multiple transactions. To make this reliable, the caller must hold the SPI mutex, instead of the underlying SPI driver. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Respond to telemetry rate changes immediatelyKeith Packard2011-10-09
| | | | | | | | Instead of waiting for the previous telemetry interval to expire, immediately switch to the new telemetry rate. This will provide more telemetry data early in the boost. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Improve TM v1.0 apogee estimateKeith Packard2011-10-08
| | | | | | | | | | | | | | | | | | | | | v1.0 boards have noisy accelerometer data caused by interactions between RF transmission and the accelerometer measurements; this noise generates a negative bias in the accelerometer readings. The net effect is that the estimated speed is lower than the actual speed, causing early an apogee estimate. By increasing the sigma value for accelerometer data, the kalman filter 'trusts' the acceleration data less, putting more weight on the barometer data. This causes the estimated time of apogee to be closer to the correct value. This reduces the response to changes in acceleration. This new value is applied solely to TeleMetrum v1.0 boards. v1.1 boards correct for this error, and hence can use the correct sigma value for the accelerometer.

* altos: Ignore ejection bumps when doing boost re-detectKeith Packard2011-10-08
| | | | | | | | An ejection charge looks an awful lot like an extra (really small) motor burn. Ignore them by averaging the acceleration during fast/coast using a /64 exponential decay filter. Signed-off-by: Keith Packard <keithp@keithp.com>

| | | | | | | | | | | | | | | | | | | | | | | | Leave the packet link disabled until we've checked the accelerometer. That way, we cannot accidentally get to idle mode when the rocket is on the rail. Signed-off-by: Keith Packard <keithp@keithp.com>
| * | altos: Delay reboot by a second to avoid re-entering idle modeKeith Packard2011-10-07
| |/ | | | | | | | | | | | | | | | | | | | | | | | | TM and Tm go into idle mode if they receive a packet after boot time. When tebooting the device over the packet link, the packet master would be (rapidly) polling the device for additional data and so the device would invariably receive a packet during bootup and go into idle mode again. Delay the reboot by a second to give the controller time to disable the master end of the packet link. Signed-off-by: Keith Packard <keithp@keithp.com>
