HAL_ADCEx_EndOfSamplingCallback in DMA mode?

Is it possible to make HAL_ADCEx_EndOfSamplingCallback fire when ADC is running in the dual mode with DMA .More specifically: On a NUCLEO-H723ZG, the ADC is started by HAL_ADCEx_MultiModeStart_DMA() and ADC2 is a slave to ADC1. The ADC conversion is ...

Resolved! How to send int values efficiently through CDC USB

Hello ST community, I am trying to send values from ADC through USB using "CDC_Transmit_FS()"The code works well but my goal is to transmit ADC values faster! (I have no option to use High Speed USB transmission mode.)The ADC values in the adcbuff ar...

__LL_ADC_CALC_VREFANALOG_VOLTAGE returns unexpected result

I am using a Nucleo-u083rc to run the ADC_MultiChannelSingleConversion Application from STM32Cube MCU Package for STM32U0 series `However, when using the helper function the value returned is completely wrong: uhADCxConvertedData[1] = 1503. Which is ...

stm32u5: HAL_ADC_Start_DMA cannot handle transfer size larger than 64k

We use STM32CubeMX and STM32U5. STM32U5 supports linked list DMA transfers. But HAL_ADC_Start_DMA() will not do a transfer larger than 64k. It only creates the first element in the list and exits. In addition, HAL_ADC_Start_DMA() doesn't give a...

Resolved! ADC example for several channels polling?

Can anybody point me to example of two or more ADC channels polling?I'm trying to measure two channels of one ADC but it looks like it reads one channel twiceInitialization:static void MX_ADC1_Init(void) { ADC_MultiModeTypeDef multimode = {0}; ...

STM32G4 HAL does not support ADC_CHANNEL_0. Bug?

We are using the ADC on an STM32G4xx for a safety project. The safety manual requires us to read VSS or VDD for ADC diagnostics. STM32G4 has ADC channel 0 internally connected to VSSA, so we are trying to use HAL_ADC_ConfigChannel() to configure ADC_...

Resolved! Why is the ADC calibration procedure for STM32F107 different from datasheet?

I am currently writing code for STM32F107VC CPU, and I want to use ADC, calibrating it first. I have noticed a strange thing in the ST HAL library.The datasheet on page 223 reads "Before starting a calibration, the ADC must have been in power-on stat...

Sending integer values through UART (STM32L0R8) (HAL drivers)

Posted on June 26, 2016 at 12:05hii am trying to send integer values from my nucleo board to my pc by using UART, i.e. you can take that sensor values. The UART example ''UART_TwoBoards_ComPolling'' in the stm32Cube that uses HAL libraries, only sen...

Resolved! How fast is ADC able to work with USB?

Hello, I am trying to send ADC data (12 bit) to pc with USB as fast as possible. Now I am using STM32F405 and configured ADC like picture below. Those data of ADC is transfered to the pc by interrupt of DMA which is cirucular mode. And the data trans...

Hello! For ADC-dual regular simultaneous (ADC1 and ADC2)HAL_ADCEx_MultiModeGetVal takes the resulting values What are the HAL functions for start-up and the interrupt response function. Without DMA. thx!
