STM32G4 op amps (>1) as inverting PGA with mid-point bias applied to non-inverting inputs - tie non-inverting inputs together?
Application needs to use all three (in STM32G431) op amps as inverting PGA handling ac-coupled signals. As there's no internal option to supply mid-point (VREF/2 with a decoupling cap at the device pin) to the non-inverting inputs of the (3) op amps ...
Stm32f4 Generate pwm signals via external trigger signal
Hi, i have a sensor that generates a TTL signal. I need a couple Pwm signal by using this external signal which is my master. I have Stm32f4 discovery MCU . Is there any way to do this goal. Please help me with any code sample or documents.
Resolved! STM32F413 flash erase doesn't work first time
Hi,I am using STM32F413 Nucleo board. I am using MDK5 IDE and HAL libraries. I made an example for reading/writing internal flash based upon a cube project. The idea is to erase interal flash and then to write some data to it. I alreay did some simil...
Will Programming the user code in FLASH MEMORY overwrite the option byte registers?
If FLASH register's offset[ex:FLASH_OPTR offset:0x020] refers from the userspace address of Flash memory,writing the user code in flash memory starting address [0x08000000] will overwrite the existing flash registers data?
Temporarily disabling the USART pins (RX and TX) in low power mode, STM32U5
Hi, I have my PCB that have a processor used as host and STM32U5 (STM32U585AII6Q) used as low power MCU. USART connection is between host and STM32U5.When I enter Stop3 low power mode, and host is turned off, there is a problem with current on USART ...
Data protection in external SRAM interfaced with STM32F4 series controller
Hi All,I have an application running on STM32F439 based controller board. And I am planning to use external SRAM.I wanted to know, how we can protect the data in external SRAM ?Or any suggestion on using external SRAM with assumption of security.Than...

I am writing a Programm on stm32cubeide. But during Debugging and Running the Programm, I habe the error Break at address "0xfffffffe" with no debug information available, or outside of program code.I don't know what it means and can I handle with th...
stm32h750vbt6 DMA is not working if active D cache
I have read previous posts ,,,I set up dma to read adc ,Although dma's destination address is allocated from AXI RAM, dma does not work when d cache is active.Can anyone share detailed information or a sample code about this?
Enabling automatic, regular wakeup with RTC timer
Dear community,I have some issues with implementing an automatic wakeup with the RTC timer on my STM32L476RG (currently on the Nucleo-Board, will be later replaced with proprietary hardware). I generally have two wakeup sources: either the L476 is wo...
