| * altos/lpc: Get USB workingKeith Packard2013-05-17
| | | | | | | | | | | | | | The lpc demo now has a USB command line. Also allocates system stack so we know when ram is tight at build time Signed-off-by: Keith Packard <keithp@keithp.com>
| * altos: Allow target-specific USB endpoint specificationsKeith Packard2013-05-17
| | | | | | | | | | | | | | The LPC has only a small number of endpoints, and those are not configurable. Let the LPC USB driver pick the IN and OUT endpoints by itself. Signed-off-by: Keith Packard <keithp@keithp.com>

| * altos/lpc: Take advantage of USART TX fifoKeith Packard2013-05-17
| | | | | | | | | | | | | | The USART has a 16-byte TX fifo; keep rough track of how full it is to avoid waiting for an interrupt after every TX byte. Signed-off-by: Keith Packard <keithp@keithp.com>

* altos/cc1111: Hack on USB driver to make Windows happyKeith Packard2013-05-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Windows modem driver is quite chatty at startup time, getting and setting the comm parameters each time the device is opened. Sometimes, when setting the parameters, the cc1111 would STALL EP0. Most of the time, Windows would happily pass this as an error back to AltosUI which would then re-try the open (and succeed, most of the time). Sometimes, Windows would stall for 30 seconds before passing the error back. This made the whole UI freeze, and I suspect most people assumed our app had died. A bit of analysis with the beagle USB sniffer and I discovered the STALL settings, but there wasn't any correlation between the data on the wire and when the STALL would be generated. So, I found a couple of other cc1111 USB stacks on the net and just looked to see how our driver differed. There wasn't anything clearly related, but there were a list of small differences: 1) Other drivers didn't bother waiting for the hardware to ack the USBADDR setting; doing it this way means we can set the address *before* acking the setup packet. It'll get set eventually, at which point the device will start responding to packets again. Easy to fix, and saves a bit of code space too. 2) The other drivers set the STALL bit for setup packets which aren't understood. This shouldn't have any effect on 'good' systems as those shouldn't ever be generating bogus setup packets anyways. The driver already handled the STALL state in the interrupt handler, the only requirement was to figure out when to explicitly set the STALL bit. That required moving the state updating code from the start of the ep0 setup handling to the end, after the setup packet had been examined and data queued in or out as appropriate. 3) Our driver explicitly queued an IN packet for any setup request that wasn't waiting for an OUT pack. This appears to tie in with the USBADDR change above as before I made that change, this change caused the driver to fail to respond to most setup packets. This was simple once the above change was made, just move the generation of the IN packet inside the code that switched to the IN state. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Generate unmodulated carrier for CC1120 test modeKeith Packard2013-05-15
| | | | | | | This sets the deviation to 0, enables the preamble and turns on the transmitter. It will sit there happily sending a bare carrier forever Signed-off-by: Keith Packard <keithp@keithp.com>

* altos: Grab SPI mutex until MPU6000 I2C mode is disabledKeith Packard2013-05-15
| | | | | | | | If other drivers use the SPI bus, the MPU6000 gets confused as its sitting on the bus looking for I2C messages. Just grab the mutex before the OS is running and hold onto it until the MPU6000 has been initialized. Signed-off-by: Keith Packard <keithp@keithp.com>

| | | | | | | telemega moves the igniters around so that E/F are now drogue/main. Add custom labels for ADC values to make parsing possible Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: gps serial routines are called ao_gps_*, not ao_ublox_*Keith Packard2013-05-15
| | | | | | | This caused the u-blox driver to use serial port 1 instead of the project-specified serial port. Signed-off-by: Keith Packard <keithp@keithp.com>

| | | | | | | | Take the gps_dump function from ao_gps_skytraq.c and move it to a new file so it can be shared with the u-blox driver. That affects every skytraq and u-blox user as they need to include the new file. Signed-off-by: Keith Packard <keithp@keithp.com>

* altos: Wait after configuring boot pin before testing itKeith Packard2013-05-07
| | | | | | | | 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>
