altos: Make telescience reliably log only when told to

2011-05-24T21:10:01+00:00

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

src-avr: Move logging printfs out of ISR call chain

2011-05-23T22:20:30+00:00

Probably not the best plan to call printf from an interrupt handler. Signed-off-by: Keith Packard

src-avr: Control log with pin on companion connector

2011-05-23T22:13:55+00:00

Use the SPI chip select (SS) which is hooked to port B0. Signed-off-by: Keith Packard

src-avr: Check RAM usage for telescience

2011-05-22T04:06:29+00:00

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

src-avr: bump ADC ring to 16 samples

2011-05-22T04:05:30+00:00

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

src-avr: Finish up telescience logging

2011-05-22T02:55:08+00:00

Adds list and delete commands, making them compatible with telemetrum and telemini equivalents. Signed-off-by: Keith Packard

src-avr: Log ADC data to eeprom

src-avr: Clean up AVR ADC code

2011-05-21T09:13:20+00:00

Remove interrupt debug variables, print channel number in ao_adc_dump. Signed-off-by: Keith Packard

src-avr: Add ADC routines to telescience

2011-05-21T09:07:43+00:00

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

src-avr: Reduce control connection interrupts

2011-05-20T09:47:20+00:00

Leave these disabled while processing stuff; otherwise we receive a steady stream of them. Signed-off-by: Keith Packard
