Werner Almesberger	bff9ca5801	fw/accel.c (adcsra): correct typo in comment	2012-07-31 10:02:34 -03:00
Werner Almesberger	206eb4d591	clean up diagnostic more and make it more robust ... A number of changes: - don't enable interrupts, since they often cause hangs (not sure why) - remove GND measurement - wait 100 us between AMUX setup and start of conversion, to let input settle - reduce delay between line setup and samping from 100 ms to 50 ms, for this is already sufficient	2012-07-01 19:40:01 -03:00
Werner Almesberger	1be433e65f	fw/accel.c (measure_ref): GND and Vbg measurement function (for diagnostics)	2012-07-01 10:38:59 -03:00
Werner Almesberger	e2f228907b	fw/accel.c (adcsra): let ADC run at 125 kHz (instead of 67.5 kHz)	2012-06-21 21:12:20 -03:00
Werner Almesberger	58e0dda95d	fw/accel.c: use timer 0 to trigger a pair of conversions (X/Y) only every 1 ms	2012-06-21 16:15:56 -03:00
