* altos: Flush the on-board mega log after every sample interval.Keith Packard2013-04-01
| | | | | | | | SPI flash parts don't need flushing, but the SD card does. Make sure the SD card contents are sane after every logging interval has passed by flushing all dirty blocks to the device. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Create the log file if it doesn't already existKeith Packard2013-03-31
| | | | | | open will return failure unless the file already exists. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Make ao_fat_readdir return real error values instead of 1/0Keith Packard2013-03-31
| | | | | | | This way, we can distinguish between 'something bad happened' and 'you're at the end of the directory'. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Increase SD card timeout at startup timeKeith Packard2013-03-31
| | | | | | | Sometimes the SD card takes 'a while' to go into idle mode at first power up. Just hang around waiting for a long time. Signed-off-by: Keith Packard <keithp@keithp.com>

* altos: Unmount file system after each testing pass in ao_fat_testKeith Packard2013-03-31
| | | | | | Otherwise, we use stale data and 'bad things' happen. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Don't add fat commands when building ao_fat_testKeith Packard2013-03-31

* altos/stm: Always check for idle IN buffer before sendingKeith Packard2013-03-31
| | | | | | | | | | | | | | Unlike the AVR and CC1111 USB drivers, the STM usb driver queues IN bytes in a local buffer instead of in the driver; this means that the driver is queuing bytes while the previous IN packet is queued for the host, which allows for overlapping execution. It also means that when the local buffer is full, we must check to see if the host has picked up the previous IN packet before trying to queue another IN packet for transmission. This is done by always waiting for the IN buffer to be ready before sending data. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Add debugging mechanism to STM USB driverKeith Packard2013-03-31
| | | | | | | | This adds a pile of debugging hooks to the USB driver to try and isolate various lockup-related issues. It's all disabled by default, of course. 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: Add sdcard read/write tracingKeith Packard2013-03-31
| | | | | | This just dumps info in trace mode about read and write commands Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Move fat mount information to separate command.Keith Packard2013-03-31
| | | | | | | This makes the mount report precise error information and then prints that with the 'M' command. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Disable CC115L debug commandsKeith Packard2013-03-31
| | | | | | now that it appears to work, leave these disabled by default Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add SD card writing functionKeith Packard2013-03-31
| | | | | | | Now that the FAT code seems to be operational, go back and add SD writing. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add logging and telem to telegpsKeith Packard2013-03-30
| | | | | | | | | | | | This turns on telemetry, APRS, RDF and data logging for telegps. Data is logged as soon as GPS has a date to create the right filename, using files of the form YYYYMMDD.LOG which just barely fits in a FAT filename. Telemetry/RDF/APRS are all separately controllable. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Export ao_fat_sync and ao_fat_full functionsKeith Packard2013-03-30
| | | | | | | ao_fat_sync() flushes the bufio data to disk along with any fsinfo changes. ao_fat_full() returns whether the file system is full. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Lock cc115l radio mutex when using global radio valuesKeith Packard2013-03-30
| | | | | | | This moves the locking up above the global state variable uses so that multiple radio users (as if we had any) won't collide. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Configure cc115l sync byte count for each radio modeKeith Packard2013-03-30
| | | | | | two sync bytes for packet mode, disable sync for rdf/aprs mode. Signed-off-by: Keith Packard <keithp@keithp.com>
* 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. Signed-off-by: Keith Packard <keithp@keithp.com>
* 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
| | | | | | Make sure the busy counts don't underflow or overflow. Signed-off-by: Keith Packard <keithp@keithp.com>
* 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: Teleshield has a radio, set HAS_RADIO in ao_pins.hKeith Packard2013-03-27

* altos: Add SDCARD and FAT16 filesystem supportKeith Packard2013-03-27

* altos: Fix config to not abort radio recv when no recv is availableKeith Packard2013-03-26
| | | | | | | Use the new radio recv define to skip disabling the receiver when there isn't a receiver. Signed-off-by: Keith Packard <keithp@keithp.com>
* 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>
