altos: Wake up on LPC usart ISR only once

2013-08-25T23:22:48+00:00

Instead of waking up after every character, wait until the FIFO is empty to reduce overhead Signed-off-by: Keith Packard

altos: Set default LPC stack to 512 bytes, Em to 384 bytes

2013-08-25T23:22:48+00:00

The default for lpc has been raised to 512 bytes, but Em doesn't have enough RAM for that. Signed-off-by: Keith Packard

altos: Use installed arm compiler for LPC

altos/lpc: Stop using burst mode for LPC ADC

2013-08-25T23:20:06+00:00

Burst mode doesn't stop after one round of conversions, so we end up getting incorrect values in whatever the last conversion register is. Just use single conversions and take an interrupt per channel. Also, slow down the ADC so that our values are more stable -- just need to make sure we get the whole conversion sequence done 100 times a second. Signed-off-by: Keith Packard

altos/lpc: Rename serial port to 'serial0'

2013-07-03T00:55:24+00:00

This lets existing serial port users find the right function. Signed-off-by: Keith Packard

altos/lpc: Add boot loader

2013-06-24T21:30:22+00:00

Support the USB boot loader, add USB pull-up support. Signed-off-by: Keith Packard

altos/lpc: Don't disable all interrupts when disabling one interrupt

2013-06-22T07:49:59+00:00

The nvic iser and icer registers read value indicates all enabled interrupts, icer writes disable the set interrupts. Re-writing icer with the current value ends up disabling all interrupts, not exactly what we wanted. Signed-off-by: Keith Packard
