src: Add explicit 'pin' argument to ao_enable_output

2012-07-14T09:44:17+00:00

This lets the cc1111 use the atomic bit operation instead of a mask, which is immune to interrupt issues as well as being a shorter code sequence. Signed-off-by: Keith Packard

altos: include targe SPI speed in get request

2012-06-27T21:34:53+00:00

STM needs it to be provided when enabling the SPI device, so just fix AVR and cc1111 to do the same. Signed-off-by: Keith Packard

altos: Add support for multiple SPI busses and sharing device drivers

2012-04-14T20:21:09+00:00

The STM32L151 has several SPI busses, and we want to use more than one, so add a 'bus' parameter to the SPI interfaces. To avoid wasting time on AVR and CC1111 processors which only use one SPI bus, elide those parameters from the actual functions by wrapping them with macros. Configuring chip select is now all macroized so that each chip can have its own version, allowing the STM to share the various SPI device drivers with the cc1111 and avr processors. Note that only the M25 driver has been ported; porting the others is 'trivial', but not necessary at this point. Signed-off-by: Keith Packard

altos: Move SPI functions to architecture-specific location

2012-04-03T05:58:54+00:00

Some architecture specific stuff needs to use core altos code, so create new ao_arch_funcs.h files per architecture that get pulled in at the end of ao.h Signed-off-by: Keith Packard
