| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most of the chip can run at 8MHz, but extended register access is limited to 6.1MHz. Instead of pushing things, just run the SPI bus at 4MHz. Signed-off-by: Keith Packard <keithp@keithp.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the GPIO pins set to 10MHz now, we can run SPI at the maximum possible speed (8MHz). Signed-off-by: Keith Packard <keithp@keithp.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The GPIO pin settings affect the output impedence, and hence the maximum speed for SPI. Cranking these to suitable values allows SPI to run at full speed. Signed-off-by: Keith Packard <keithp@keithp.com>

| |_|/ |/| | | | | | | | | | | | | | | | | | | | | | | From Tridge -- MPU6000 rev C4 and C5 are broken, having accelerometer values in the wrong range. This commit just adds comments which note this; experimentation will be required to actually sort out what's going on. Signed-off-by: Keith Packard <keithp@keithp.com>
* | | altos: Add Kalman filter to MicroPeakKeith Packard2013-01-16

* | | altos: Correct model error covariance matrixKeith Packard2013-01-16
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Finally found a couple of decent references on how to set the model (process) error covariance matrix. The current process matrix turns out to be correct for a continuous kalman filter (which isn't realizable, of course). For a discrete filter, the error in modeled acceleration (we model it as a constant) needs to be propogated to the speed and position portions of the matrix. The correct matrix is seen in this paper: On Reduced-Order Kalman Filters For GPS Position Filtering J. Shima 6/2/2001 This references an older paper which is supposed to describe the derivation of the matrix: Singer, R.A., “Estimating Optimal Tracking Filter Performance for Manned Maneuvering Targets,” IEEE Transactions of Aerospace and Electronic Systems, AES-5, July 1970, pp. 473-483. This change has a minor effect on the computed correction coefficients; it should respond more reasonably to acceleration changes now. Signed-off-by: Keith Packard <keithp@keithp.com>

| * micropeak: Record samples before boost detectKeith Packard2013-01-12
| | | | | | | | | | | | | | | | | | This saves a ring of 16 samples while waiting for boost, and then goes back through those looking for the first sample higher than the ground and writes the remaining ones to the log so that we get a more complete log of the flight Signed-off-by: Keith Packard <keithp@keithp.com>

| | * | | altos: Make micropeak 'serial' interface workKeith Packard2012-12-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I prototyped the mpserial interface on a breadboard and tuned the circuit to register the LED correctly. Then adjusted the serial code to send bits at the right speed and format. The logging contents are now in hexdecimal with a CCITT CRC-16 computed to verify correct reception.

| * | | | altos: Time out reading packet data from cc1120 after 100msKeith Packard2013-01-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sometimes the radio will give a spurious wakeup indicating that a preamble seems to have arrived, but no packet data will appear. In this case, abandon the packet reception and go back to waiting for a preamble again. This releases the SPI bus for other users and also avoids missing packets.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the radio drops out of RX or TX mode due to an error, it changes the MARC status, and sends pulse down a configured GPIO. Use this to tell when something 'bad' happened during TX or RX so that we can recover from losing the SPI bus in the middle of transmission or reception. Without this, the radio would change state and we'd never know, leaving the radio code waiting for an interrupt that would never arrive. Signed-off-by: Keith Packard <keithp@keithp.com>
