altos/stmf0: Support PA11/PA12 remapping

2015-02-01T15:44:52+00:00

Small pin-count versions of the STMF0 can remap PA11/PA12 on the same pins as PA9/PA10. These are used by USB, so have the USB driver deal with remapping them. Signed-off-by: Keith Packard

altos/stmf0: Re-implement fast ADC code for stmf0

2015-01-28T04:41:15+00:00

This creates a ring buffer for ADC data so that ADC fetching can run in parallel with other activities. Signed-off-by: Keith Packard

altos/stmf0: Add CRC driver

2015-01-28T00:55:27+00:00

Sets up the stm32f0 CRC hardware, exposing inline functions to access it. DMA access is possible, but usbtrng can't use that. Signed-off-by: Keith Packard

altos/stmf0: Remove remaining stm32l bits from stm32f0 code

2015-01-27T17:36:19+00:00

These were left over from the stm32f0 initial implementation work; now it's more useful to list only the bits which are valid. Signed-off-by: Keith Packard

altos/stmf0: Add ADC and DMA APIs

2015-01-27T06:14:57+00:00

The ADC api is what USBtrng wants; a way to repeatedly read a single ADC input as fast as possible. Signed-off-by: Keith Packard

altos/stmf0: Add faster USB path

2015-01-27T06:12:40+00:00

This adds a way to allocate private USB buffers for sending data without needing to copy it again. It requires ensuring that all accesses are 16 bits aligned to 16 bit boundaries. Signed-off-by: Keith Packard

altos/stmf0: Fix linker scripts to make ao_boot work

2015-01-27T06:10:47+00:00

The flash loader ended up assuming ao_boot was at the start of ram, while the application stuck it after the interrupt table (where it needs to go). Signed-off-by: Keith Packard

altos: Add self-flash support for STM32F042 processor

2015-01-26T03:35:19+00:00

Also moves the usual address for applications out of the way of the flash loader. Signed-off-by: Keith Packard

altos: Initial STMF04x support

2015-01-26T00:42:39+00:00

Basic clock configuration, OS support, LED and USB drivers. Signed-off-by: Keith Packard
