altos/stm: Let products override AO_LED_TYPE for stm processors

2018-06-17T19:28:51+00:00

No need requiring it to be uint16_t Signed-off-by: Keith Packard

altos/stm: Define ADC channels for TEMP and V_REF

2018-06-17T08:10:04+00:00

These are fixed at 16 and 17. Signed-off-by: Keith Packard

altos/stm: Remove unused ADC names from ao_adc_single_stm.c

2018-06-17T08:09:58+00:00

altos/stm: Enable HSI timer when HAS_ADC_SINGLE is set

2018-05-29T02:18:48+00:00

The ADC unit always uses the HSI timer. Signed-off-by: Keith Packard

altos/stm: Add polling ADC sampler API

2018-05-28T23:09:19+00:00

This just fetches ADC values on demand instead of loading them periodically into a ring buffer from the timer interrupt. Signed-off-by: Keith Packard

altos/stm: Add per-LED port/pin mode in LED code

2018-05-17T05:06:12+00:00

If you've got a complicated LED pin arrangement, you can ask for each one to be configured separately, instead of using groups in a couple of GPIO registers. The code isn't as efficient this way, but at least it's easy to read. Signed-off-by: Keith Packard

Remove ao_radio_cal from stm products without radios

2018-04-27T02:33:48+00:00

Products without a radio don't need this value. Signed-off-by: Keith Packard

altos/flash-loader: On STM, don't include ao_usb_disable

2018-04-27T02:24:21+00:00

This saves a bit of space, keeping the flash loader under 4k on fox Signed-off-by: Keith Packard

altos/stm: Simplify ao_usb_write a bit

2018-04-27T02:24:21+00:00

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

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
