* altos: Use max of 64 previous orient values when checking pyro limitsKeith Packard2018-04-26
| | | | | | | | | Instead of checking just a single measurement to see if the orientation is outside of the desired limits, use the maximum of 64 previous values to that rapidly changing orientation won't accidentally enable a pyro channel if sampled at the 'wrong time'. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Simplify ao_usb_write a bitKeith Packard2018-04-26
| | | | | | | Remove unnecessary 'offset' param (was always passed zero). This also makes some code conditional on that value no longer necessary. Signed-off-by: Keith Packard <keithp@keithp.com>

* altos/stmf0: use double buffering for USB rx dataKeith Packard2018-01-07
