* avr: Block interrupts while executing SPI slave codetelescienceKeith Packard2012-05-26
| | | | | | | Any interrupts do very bad things to our SPI reliability. Block interrupts for the whole of the SPI slave ISR. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos-avr: Include serial/flight in companion commandsKeith Packard2011-08-13
| | | | | | | This lets TeleScience log these values so the log can be matched with a suitable TeleMetrum log. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Report log format in the version commandKeith Packard2011-08-13
| | | | | | | | | | Cherry-pick from 8624213ee204bfdcb219c65b3618751d8278d9db This will make it easier to figure out what the contents of the flash should look like from altosui; the current 'guessing' mechanism will not scale to many more formats. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos-avr: Store TM tick and state in log, get logging on/off workingKeith Packard2011-08-12
| | | | | | | | | | | To sync TM and TS data after flight, store the TM tick data in the log along with the TM state. This should provide sufficient data to synchronize the two data streams. Use the TM state to enable/disable logging, log from boost to landing and otherwise do not log. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos-avr: Completely replace the spi slave codeKeith Packard2011-08-12
| | | | | | | | | | | | | | Turns out the AVR we're using sucks at doing SPI slave. To get it running at a reasonable data rate, I had to completely gut the 'sensible' code and run everything from the ISR with interrupts disabled. Even with this, the maximum SPI clock rate is somewhere around 200kHz. That's due to the singled buffered nature of the transmit queue, the amount of time available between finishing one byte and starting the next is very very small.

* altos-avr: Add SPI-slave companion supportKeith Packard2011-07-13
| | | | | | | | Listen on the SPI slave port for commands from TeleMetrum. Run logging during flight, based on flight state. Return recent data for telemetry. Signed-off-by: Keith Packard <keithp@keithp.com>
* src-avr: Improve speed of LCD transfers, add hex-code character inputKeith Packard2011-06-04
| | | | | | | | | Use a delay loop instead of waiting for clock interrupts to get closer to maximum LCD update rate. Add \ escaped hex codes in output testing command. Signed-off-by: Keith Packard <keithp@keithp.com>
* src-avr: Add LCD driver for NHD-C0216CU-FN-GWB-3V displayKeith Packard2011-06-04
| | | | | | | Initializes the Newhaven display and has a few simple commands to show some text. Signed-off-by: Keith Packard <keithp@keithp.com>
* src-avr: Run CPU at 8MHz, even with a 16MHz xtalKeith Packard2011-06-04
| | | | | | This allows the Teensy to run at 3.3V. Signed-off-by: Keith Packard <keithp@keithp.com>

* altos: Make telescience reliably log only when told toKeith Packard2011-05-24
| | | | | | | | | | | | | | Use a pull-up on telescience and tri-state input on telemetrum at boot time. Enable logging by pulling the TM output low and enabling as an output, disable by pulling the TM output high and switching back to input mode. Also, ignore pin state changes for 5 seconds at boot to give things a chance to settle down. Should work when both boards are powered up together. Signed-off-by: Keith Packard <keithp@keithp.com>
* src-avr: Move logging printfs out of ISR call chainKeith Packard2011-05-23
| | | | | | Probably not the best plan to call printf from an interrupt handler. Signed-off-by: Keith Packard <keithp@keithp.com>
* src-avr: Control log with pin on companion connectorKeith Packard2011-05-23
| | | | | | Use the SPI chip select (SS) which is hooked to port B0. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Signal ascent using P1_2 (0 = ascent, 1 = other)Keith Packard2011-05-23
| | | | | | This can control an external recording device to log data only during ascent. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos, altosui: Add igniter mode (dual, apogee, main)Keith Packard2011-05-23
| | | | | | This provides for redundant charges for either apogee or main. Signed-off-by: Keith Packard <keithp@keithp.com>
* src-avr: Check RAM usage for telescienceKeith Packard2011-05-21
| | | | | | | ATmega32u4 has only 2.5kB of ram, so check the output of the compiler to make sure it will work. Signed-off-by: Keith Packard <keithp@keithp.com>
* src-avr: bump ADC ring to 16 samplesKeith Packard2011-05-21
| | | | | | | We've got ram for it at this point, and it's nice to have more data from before boost detect. Signed-off-by: Keith Packard <keithp@keithp.com>
* src-avr: Finish up telescience loggingKeith Packard2011-05-21
| | | | | | | Adds list and delete commands, making them compatible with telemetrum and telemini equivalents. Signed-off-by: Keith Packard <keithp@keithp.com>

* src-avr: Add ADC routines to telescienceKeith Packard2011-05-21
| | | | | | | Note that SLEEP mode must be disabled or extra ADC interrupts occur, which messes up saving ADC values to the right channel. Signed-off-by: Keith Packard <keithp@keithp.com>

* src-avr: Disable USB interrupts while we're not interestedKeith Packard2011-05-20
| | | | | | | | We leave USB data lying around until called for, which results in constant badgering if interrupts are enabled. Disable them until there isn't any data left. Signed-off-by: Keith Packard <keithp@keithp.com>

* src-avr: Suspend interrupts while switching stacksKeith Packard2011-05-18
| | | | | | | | Setting the stack pointer takes two instructions, so make sure we don't get an interrupt in the middle of it. Let the restoration of SREG set the interrupt flag as appropriate. Signed-off-by: Keith Packard <keithp@keithp.com>
