STM32F4 using DMA and ADC with LL

Hello, I'm working with a nucleo F401RE board and the LL drivers, I have set up the ADC in DMA mode, checking into the DMA register all seems right, but when I start the ADC it converts only one value and than it stop, the ADC is triggered from an EX...

Unreadable flash due to power failure

We met with strange problem with STM32H743. Could you please advice how to diagnose the following bug/effect of built-in flash :we use STM32H743 at our device. We calibrate the device within assembling procedure. The calibration data stored in built-...

STM32U5 GPDMA

Hi,The GPDMA of the STM32U5 is much more complex to configure than the DMA of the other STM32. I would like to know in which applications GPDMA is better than DMA and also would like to know if ST has plans to use GPDMA in future general purpose micr...

How to configure Two channel ADC Technique in STM32F413ZH Controller ?

If I vary any one channel Input through POT, it is reflecting in another ADC Channel also... can anyone help me regarding this ?

Hi, Is there a way to use an J-Link debugger with the STM32 ST-Link Utility? Greetings Eric

In our application,under Power OFF Condition,we will be using static situation of RAM supply of some 20 bytes(LSE is not running at all and no RTC crystal is used)and all other Peripherals will be in the OFF Condition.For this condition we need IDD_VBAT.

Part Number: STM32F091VBPart Family: STM32F091xxQuery Description:From the datasheet of STM32F091VB, the current IDD_VBAT through the VBAT Pin is noted as belowThe data in the above table is given in the condition where LSE and RTC in ON.In our appli...

STM32G4 check if programmed previously

You can't reprogram flash double words on the stm32g4 even if the were programmed to 0xFFFF'FFFF'FFFF'FFFF.Does anyone know if it is possible to check if the 0xFFFF'FFFF'FFFF'FFFF value I read from a specific flash position has previously been progr...

I think I am enabling packet error checking on specific I2C reads from a peripheral device. I do this by setting CR1 bits PEC, POS, and ENPEC, then doing a HAL_I2C_Mem_Read. I get expected results from the register read. Should PEC be zero?

I look at SR2 PEC contents (most significant 8 bits), and they always are zero. Is that normal?
