altos: Rework packet receive for cc1120

2014-07-05T07:38:10+00:00

Instead of blocking on PQT, just set up the receiver to start going and when the first bit interrupt comes in, grab the SPI bus if possible and configure it for reception. This improves sensitivity in the radio by a significant amount while making the code conceptually a bit nicer. Signed-off-by: Keith Packard

altos/lpc, altos/stm: ARM requires ISB after switching stack pointers

2013-10-08T04:53:53+00:00

This sticks a barrier in the CPU to prevent using the wrong stack register past the change. 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: Filter ADC inputs

2013-06-15T08:21:45+00:00

They're amazingly noisy on EasyMini, so just filter them as the only thing we use them for is battery and pyro numbers. Signed-off-by: Keith Packard

altos/lpc: Make ADC inputs work

2013-06-15T08:21:39+00:00

They're still very unstable (bouncing around a lot), but at least they seem to report useful stuff now. Signed-off-by: Keith Packard

altos/lpc: Missing parens around ao_gpio_set macro

altos/lpc: Use separate interrupt stack

altos/lpc: Fix ao_enable_input, add ao_enable_analog

altos: Add LPC spi driver

altos/lpc: Get USB working

2013-05-17T10:50:07+00:00

The lpc demo now has a USB command line. Also allocates system stack so we know when ram is tight at build time Signed-off-by: Keith Packard
