altos/lpc: Add (void *) cast to fix alignment warning

2017-04-21T23:40:58+00:00

The -Wcast-align warning is generated when this cast is not present. Signed-off-by: Keith Packard

altos: Add one-byte SPI output routine for LPC and STM cores

2016-03-26T23:07:20+00:00

This allows for SPI output at interrupt time, one byte at a time. Signed-off-by: Keith Packard

Revert LPC usb performance improvements

2015-02-05T23:00:56+00:00

There's something screwy going on, sticking garbage in the input buffer at boot time Signed-off-by: Keith Packard

Set version to 1.5.9.1

altos/lpc: Switch LPC SPI driver to interrupt-driven

2014-12-23T01:27:09+00:00

This improves performance for SPI transfers, while allowing other tasks to get work done during longer SPI transfers. Signed-off-by: Keith Packard

altos/lpc: Disable JTAG when using pins for GPIO

2014-11-07T00:04:56+00:00

JTAG is enabled by default, making those pins not support GPIO unless specifically configured. Signed-off-by: Keith Packard

altos/lpc: Declare SPI send parameters as const

2014-11-07T00:04:14+00:00

This matches STM Signed-off-by: Keith Packard

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
