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/stm: Expose ao_gpio_set which sets a specific GPIO pin

2012-07-14T08:28:55+00:00

Will need versions for other architectures 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: Clean up usage of port parameters

2012-06-27T06:01:58+00:00

Make stm port parameters always be pointers; this avoids the confusion where some macros took '&port' and others took a bare 'port', and also unifies code to run on other processors in a consistent fashion. Signed-off-by: Keith Packard

altos: STM i2c work.

2012-05-07T05:47:33+00:00

Start now driven by interrupts Send now done with DMA and interrupts Signed-off-by: Keith Packard

altos: Add STM I2C recv and stop funcs

2012-04-26T06:26:57+00:00

Recv doesn't appear to work with more than one byte Signed-off-by: Keith Packard

altos: Starting to write cc1120 driver

2012-04-17T18:01:18+00:00

This does "something" in radio test mode, appearing to generate a 730MHz signal. 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: add STM I2C driver.

2012-04-09T07:08:20+00:00

Not well tested yet... Signed-off-by: Keith Packard

altos: Allow STM DMA channels to be reserved for one use

2012-04-09T07:05:18+00:00

This allows a single user of a DMA channel to reserve it for use without needing to lock the mutex; this is required for DMA from the ADC to work on megametrum as it wants to start DMA from an interrupt handler, which cannot block on a mutex. Signed-off-by: Keith Packard
