Stm32h7 adc example

testhal ADC STM32H743 example improvement. I was testing the ADC of the STM32H743, and found a few things that could improved in the testhal example. 1. ADC1_IN0 is tied to PA9_C, a dedicated analog pin not available on the nucleo board. To sample PA0 instead replace IN0 by IN16 in .STM32F0 uses internal reference voltage (VREFINT). This internal voltage is connected to ADC_IN17 (channel 17) and can be measured. Moreover, the precise voltage of VREFINT is individually measured for each part by ST during production test and stored in the system memory area with respect to supply voltage Vdd = 3.3V.

If enabled, ADC will Continuously sample and convert. If disabled, only one sampling and conversion will be performed and than A/D will stop. Scan Conversion mode. Configures the sequencer of groups. If it is disabled, conversion is performed in a single conversion mode (the one defined in rank 1). If enabled, conversions are performed in ...[PATCH v2 6/7] iio: adc: stm32-adc: add vrefint calibration support From: Olivier Moysan Date: Wed Sep 22 2021 - 11:35:28 EST Next message: Olivier Moysan: "[PATCH v2 7/7] iio: adc: stm32-adc: use generic binding for sample-time" Previous message: Olivier Moysan: "[PATCH v2 5/7] iio: adc: stm32-adc: add support of internal channels" In reply to: Olivier Moysan: "[PATCH v2 5/7] iio: adc: stm32 ...Re: STM32H7 ADCv4 patches. Postby mikeprotts » Wed May 26, 2021 2:46 pm. I've just been taking a look at this (using an STM32H743 old style). The documents suggest that the VREF and TS values have to be taken from ADC3, but the sample uses ADC1. Also the channels need to be changed to 19 (VREF) & 18 (TS), using SMPR2.*PATCH v3 0/7] iio: adc: stm32-adc: add internal channels support @ 2021-09-24 8:34 Olivier Moysan 2021-09-24 8:34 ` [PATCH v3 1/7] dt-bindings: iio: stm32-adc: add generic channel binding Olivier Moysan ` (8 more replies) 0 siblings, 9 replies; 11+ messages in thread From: Olivier Moysan @ 2021-09-24 8:34 UTC (permalink / raw) To: Alexandre Torgue, Fabrice Gasnier, Jonathan Cameron, Lars ...
