altos: Report log format in the version command

2011-08-13T20:14:26+00:00

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

altos-avr: Completely replace the spi slave code

2011-08-12T11:41:19+00:00

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. 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
