altos: Declare port register type only in arch header

2014-11-06T23:58:42+00:00

Instead of defaulting to 8 bits, explicitly require declaration of the type of the port register for each architecture. Signed-off-by: Keith Packard

altos: Fix nanopeak compile

2014-04-07T05:27:37+00:00

Nanopeak uses port B bit 3 for the LED instead of bit 4. Fix the async code to support arbitrary bits for the serial LED. Signed-off-by: Keith Packard

altos: Replace C code attiny async output with inline asm

2014-04-07T02:48:07+00:00

Using inline asm instead of C ensures that compiler changes will not affect the timing of the serial data. Signed-off-by: Keith Packard

altos: Move micropeak sources around

2013-09-15T21:11:50+00:00

This sticks the micropeak sources in appropriate directories, rather than in the micropeak product directory so that they can be shared with future micropeak-style products. Signed-off-by: Keith Packard

altos: Check for MS5607 MISO low before sleeping

2013-08-27T01:47:27+00:00

If the MISO line goes low before we manage to configure the interrupts, we'll miss it entirely unless we check the pin explicitly. Signed-off-by: Keith Packard

altos: Add EXTI_PIN_NOCONFIGURE to exti interface, use for MS5607

2013-05-20T03:04:29+00:00

This asks the EXTI code to not mess with the pin configuration so that the MS5607 driver can get interrupts on the MISO pin while still using it for SPI. Signed-off-by: Keith Packard

altos/attiny: Fix ao_spi_get_bit/ao_spi_put_bit macros

2013-05-20T02:51:32+00:00

These were never written, so just use ao_spi_get/put_mask. A precursor to changing how the MS5607 drives the SPI bus Signed-off-by: Keith Packard

altos: Move ao_notask to core

2013-05-08T03:16:53+00:00

The STM flash loader wants to be taskless too, share this very simple implementation of sleep/wakeup. Signed-off-by: Keith Packard

altos/attiny: Remove debugging code which frobs PB1

2012-10-31T04:31:27+00:00

This was clearly stuck there to debug something; not a good idea... Signed-off-by: Keith Packard

altos/micropeak: Clock micropeak at 250kHz to save power

2012-10-31T02:41:08+00:00

This reduces average current consumption from 2mA to .4mA. This makes the battery last longer, but also gets the current under something that the typical CR1025 battery can support. Would be nice to reduce current even further; cheap CR1025 batteries still seem to fade a bit at this current level. Signed-off-by: Keith Packard
