altos/stm: Add better byte-level SPI api2016-06-30T02:17:45+00:00Keith Packardkeithp@keithp.com2016-06-29T01:39:31+00:00urn:sha1:61ad8e5bf428246ac89cad7cb9a1edf2ef735fd5
This provides inline functions for sending and receiving individual
bytes, and setup/finish functions to wrap them in. This make the byte
sending respect the SPI hardware interface requirements.

altos: Block interrupts while waking tasks sleeping on timers.2016-06-30T02:17:45+00:00Keith Packardkeithp@keithp.com2016-06-29T00:04:59+00:00urn:sha1:a7e0bb5eb661cfde31c383d605cb9cb8ca568bc7
Interrupts may not be blocked in the timer ISR, but they need to be
while walking the pending timer list and moving tasks back to the run
queue.

Revert "altos/stm: Run scheduler code on interrupt stack"2016-04-30T15:51:53+00:00Keith Packardkeithp@keithp.com2016-04-30T15:46:52+00:00urn:sha1:7695da327ff8861a858b6695f4849fa1399548d8
This reverts commit 6a9546413d6a236c010e806b50506d870961d074.
This causes the device to stop reliably handling interrupts.
altos/stm32l: Add support for software-driven HW flow control2016-04-25T22:48:47+00:00Keith Packardkeithp@keithp.com2016-04-25T22:48:47+00:00urn:sha1:27319e4edbc503f193475b437fa5fe2937d47cbe
This allows applications to request that the flow control bits be
driven from software rather than hardware, permitting more flexible
pin configuration.

altos: Use TXE instead of TC for serial on STM32l2016-04-25T15:49:16+00:00Keith Packardkeithp@keithp.com2016-01-20T07:53:27+00:00urn:sha1:7c9a111ac1c88467ce28e03b4a9d3eabc9d7015b
Using TXE allows for full-speed communication, rather than waiting for
each byte to be transmitted before inserting the next into the queue.

These set or clear a group of bits in a single GPIO register all together.
