Hi,I'm using a Nucleo-H723ZG board with 1.8V VDD.According the schematic, VDDA and VREFP is same as VDD(verified VREFP to be 1.8V using multi-meter).If I use the ADC3 analog temperature senor I get strange values.I get values like -33°C while the DTS...

The temperature sensor channel configuration is generated by CubeMX / STM32CubeIDE.ADC3_SAMPLETIME_2CYCLES_5 is st by CubeMX generator, there is no GUI field to change.One could expect that this value generated by the ST Software is correct :/But ind...

Hi @Community member thank you for your kind help and explanation.In general I tried to keep it very simple by using polled mode.Here is the MX_ADC3_Init: hadc3.Instance = ADC3; hadc3.Init.ClockPrescaler = ADC_CLOCK_ASYNC_DIV1; hadc3.Init.Resol...

Hi @F.Belaid ,thanks for your reply.I got a chance now to try it....sorry for the delayfloat temperature = (float)__LL_ADC_CALC_TEMPERATURE(1800,ADCValue,ADC_RESOLUTION_12B));It does seem to do exactly the same as with __HAL* macro.The raw ADC decim...

Hi KnarfB, yes I know. There are pictures of the bottom side, but (for me) its not visible if there are long male connectors, or if its just the soldered-in female connector. There is no angled picture where I could see it clearly.

How to use ADC3 temperature sensor for STM32H723ZG if VDD=VDDA=VREFP=1.8V?

Hi, I wonder if the "newer" STM32H7 NUCLEO boards (e.g. NUCLEO-H723ZG) still have the male pins on the bottom side? In the pictures I found its not really visible. My NUCLEO-F767ZI board has female sockets on top side and male pins on bottom side.
