STM32 MCUs products

Resolved! I use STM32F373VCT6. I use all 3 of its embedded SDADCs with external Reference of 3V. I am wondering what would be the current requirement (output current of the REF device) I should be looking for when selecting the Ext. REF.

STM32F373 SDADC injected sequence using DMA drifts through the data buffer

I am having trouble using the DMA with SDADC. The samples are coming in ok but their sequence in the buffer drifts through it. Anyone can help? i.e. every channel is open to the air except for one input i have a voltage applied. This value you can cl...

Resolved! f373 SDADC one input is pulling down.

Hello, I have a custom designed board with 7 analog inputs on sigma delta ADC's.6 of my inputs are working properly. I have a software issue.When I erase the flash or de-solder the mcu I can measure the correct voltage from my test points.But when I ...

Resolved! Cannot get continuous data from SDADC

Background: I use the stm32373c evaluation board to make project. One part of the project is to use the 16bit SDADC to acquire sinewaveform generated from function generator and send the data to pc sw thr. uart. I follow the evaluation board example ...

How use external trigger SDADC correctly of STM32F3 ?

Hi everyone ! I want configure external trigger of sdadc in stm32373c-eval. Trigger external is TIM13 configured at 1700Hz (purple signal), when HAL_SDADC_InjectedConvCpltCallback execute i did that toggle LED and the toggle is doing 16's in one peri...

Resolved! I can only change the gain of the SDADC once, not twice or more

I want to change the SDADC gain while the MCU STM32F373VBTx is running.That works, but only one time.First, at the initialization of the SDADC, the STM32 CubeMX set the predefined gain.Second, I set the gain by reading values from variables. That wor...

Why is DMA state READY when I want to abort DMA?

Hi!I'm doing SDADC and I think there is some issues with the DMA for SDADC in STM32CubeIDE 1.7.0.First, I have enabled DMA for SDADC1, SDADC2, SDADC3 and I have selected InjectedConversion = ENABLE. Then I run this function. volatile static int16_t S...

Why does the DMA not read the Sigma Delta ADC?

I have sigma delta 16-bit ADC enabled. It works great with regular interrupt. No problem there, but when I'm trying to use DMA with Sigma Delta ADC, then nothing happens. It will only be zeros.I have 9 SDADC zero referenze on SDADC1, 3 SDADC zero ref...

Resolved! How can I use Capture Compare as external trigger source?

Hi!This might be a simple question, but I still haven't solved it. I want to create an external trigger source for SDADC 16-bit and I have selected TIM12 Capture Compare 1 as external trigger source. Then I have enable the Output Compare, because I d...

Sigma-Delta ADC STM32F373 calibration problem

Hi,I have connected three channels of the SDADC in the STM32F373 with an external voltage reference of 1.225V. The selected mode of the ADC is Single-ended zero-volt reference mode, and i am reading these channels using the "injected conversion" as i...
