On this 32-bit arch there's no need to use the long version of the format
specifier. It's only there to appease the compiler which checks the type
of the args passed to printf. Removing the "l" saves a bit of code space.
stm32/adc: Use mp_hal_pin_config() instead of HAL_GPIO_Init().2018-05-02T02:17:45+00:00Damien Georgedamien.p.george@gmail.com2018-05-02T02:06:23+00:00urn:sha1:d4f8414ebdc5e61ef9127778ab0ce4c09f8839e9
This makes ADCAll work correctly on L4 MCUs.
stm32/adc: Add support for H7 MCU series.2018-05-01T05:36:11+00:00iabdalkaderi.abdalkader@gmail.com2018-04-01T01:20:21+00:00urn:sha1:8c12f1d916b119596c115ed7ce73eaf3f3a9cd7a
ADC3 is used because the H7's internal ADC channels are connected to ADC3
and the uPy driver doesn't support more than one ADC.
Only 12-bit resolution is supported because 12 is hard-coded and 14/16 bits
are not recommended on some ADC3 pins (see errata).
Values from internal ADC channels are known to give wrong values at
present.
stm32/adc: Factor common ADC init code into adcx_init_periph().2018-04-11T04:46:13+00:00Damien Georgedamien.p.george@gmail.com2018-04-11T04:46:13+00:00urn:sha1:f1073e747d0489154942a0d0e0585bc6943df448
The only configuration that changes with this patch is that on L4 MCUs the
clock prescaler changed from ADC_CLOCK_ASYNC_DIV2 to ADC_CLOCK_ASYNC_DIV1
for the ADCAll object. This should be ok.
stm32/adc: Fix config of EOC selection and Ext-Trig for ADC periph.2018-04-11T04:29:37+00:00Damien Georgedamien.p.george@gmail.com2018-04-11T04:29:37+00:00urn:sha1:1d6c155d6ac1c335e66b427cbead55b4217fc097
A value of DISABLE for EOCSelection is invalid. This would have been
interpreted instead as ADC_EOC_SEQ_CONV, but really it should be
ADC_EOC_SINGLE_CONV for the uses in this code. So this has been fixed.
ExternalTrigConv should be ADC_SOFTWARE_START because all ADC
conversions are started by software. This is now fixed.
stm32/adc: Factor code to optimise adc_read_channel and adc_read.2018-04-11T04:28:06+00:00Damien Georgedamien.p.george@gmail.com2018-04-11T04:28:06+00:00urn:sha1:06807c1bde6885a070be78e63271ad596e31c06c
Saves 200 bytes of code space.
