* altos: Get CC115L radio working.Keith Packard2013-03-29
| | | | | | | | | | | | | | | | This involved figuring out which GPIO signal would reliably indicate that the transmitter was finished; I ended up using the PA_PD bit for this. This also converts all of the radio users to the long packet support as the CC115L has only a 64-byte fifo, not large enough to hold either an RDF tone or a regular AltOS telemetry packet. This also renames the public API for sending APRS packets from ao_radio_send_lots to ao_radio_send_aprs, which is at least more accurate. The workings of that API haven't changed, just the name.

* altos: Add temporary RF power settingsKeith Packard2013-03-29
| | | | | | | | | | These expose the raw cc115l and rfpa0133 register settings so that we can calibrate them against measured power outputs. I've tested them to verify that they change how much power the board consumes, so they're clearly doing something... Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add FAT32 support. And lots more testing.Keith Packard2013-03-29
| | | | | | | | Generalizes the FAT code to deal with either 16-bit or 32-bit versions. The testing code now runs over a variety of disk images to check for compatibility on all of them. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: seek forward on FAT cluster chain instead of restartingKeith Packard2013-03-28
| | | | | | | | This improves sequential file performance by taking advantage of any previous cached cluster/offset pair and starting from there when the cluster changes rather than starting from scratch at the begining again. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add a simple cache for the FAT position->cluster computationKeith Packard2013-03-28
| | | | | | | This improves read/write performance with large files by not re-walking the cluster chain for every operation Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Clean up fat driver API. Improve fat testKeith Packard2013-03-28
| | | | | | | | Make FAT api provide reasonable error return values, change the tests to write and then read a pile of files, checking that the contents are correct (using md5sum). Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add sanity checking to busy counts in bufio driverKeith Packard2013-03-28

* altos: Use FTDW, clear DATA bit. Disable backup write protectionKeith Packard2013-03-27
| | | | | | | | | The newer(?) chips in telegps didn't like the previous programming scheme, so go back to fixed time for write, which does an implicit erase before every write. Also clear the DATA bit, which is only needed for double word erase/programming. Signed-off-by: Keith Packard <keithp@keithp.com>

* altos: Fix config to not abort radio recv when no recv is availableKeith Packard2013-03-26

* altos: Allow radio recv and xmit to be separately configuredKeith Packard2013-03-26
| | | | | | | The CC115L is xmit only, so split out the functions and provide defines to check for xmit or recv separately as needed. Signed-off-by: Keith Packard <keithp@keithp.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

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.
