altos/stm: Align 'data' to 8 bytes, just like textram

2017-12-12T23:31:27+00:00

The textram section must be aligned to 8 bytes to keep the linker happy. However, if that section contains no data, the declaration will set the __data_start__ value to that alignment, but the data section itself would start on a 4-byte alignment, potentially 4 bytes lower than the value indicated by __data_start__. This completely scrambles initialized memory as the startup code will copy the data segment to __data_start__, 4 bytes off of the actual data segment start. Fix this by forcing the data segment to also be aligned to 8 bytes. Signed-off-by: Keith Packard

altos: Actually store current MPU9250 data in data ring

2017-12-11T22:08:32+00:00

The ring is updated when the ADC finishes; all of the other sensor data needs to be copied in at that point. Signed-off-by: Keith Packard

altos: Allow building with newlib + avr stdio on ARM

2017-12-11T20:20:25+00:00

Redefines some stdio bits so that we can build with either pdclib or newlib + avr stdio. Signed-off-by: Keith Packard

altos/stm: Add AO_EXTI_MODE_PULL_NONE

2017-11-12T00:36:41+00:00

This is clearer than using '0'. Signed-off-by: Keith Packard

altos/stmf0: Initialize UART RTS/CTS before turning it on

2017-06-28T06:37:49+00:00

If you try this after the UART is running, it won't work. Signed-off-by: Keith Packard

altos: Make CDC ACM 'line coding' public

2017-05-05T05:10:36+00:00

This allows other systems to see what baud rate the host has requested. Signed-off-by: Keith Packard

stm: Add more mask-based GPIO controls

2017-04-04T23:04:25+00:00

Lets cortexelf do more things with groups of pins, rather than one pin at a time. Signed-off-by: Keith Packard

stm: Add a few more GPIO functions to make dealing with the 1802 easier
