SDRAM Chip Select & Clock Enable connections in STM32H750

Hi team,We are using STM32H750 MCU in our design. We are interfacing an SDRAM memory to the MCU using FMC. But we have doubt on the SDRAM chip select & clock enable signals. We are planning to use FMC_SDNE0 & FMC_SDCKE0. But In Discovery kit, FMC_SDN...

STM32F407VG Custom Break over UART1 for DMX transmitting

Hi everyone,I am trying to output DMX data over UART1 at 25Hz. Therefore I need a break for 88us. My plan was to take control over the port and set it into GPIO Mode. After 88us I set it back to UART mode. For breaktimes > 250us it works fine. But be...

Function of integer calling in another file skipped partly

Being here just 30 seconds.I have two questions, where the first one is about using a typdef union{} in other files, see my code here  // a.h  typedef union{    float vf;    unsigned char vuc[4];  }fc4;     // a.c  fc4 vfc4a;     // b.c  #include "a....

STM32G474: ADC Offset Compensation really not possible with Hardware Oversampling?

Regarding the ADC, with Gain Compensation, Offset, and Hardware Oversampling:Reference manual (RM0440 Rev 5) page 647 and also page 664 say:"Offset correction is not supported in oversampling mode. When ROVSE and/or JOVSE bit is set, the value of the...

Safely reading a filterred input with an IRQ Handler (input capture mode with input filter)

On an STM32F0 I would like to read a digital signal using the input filter. I configure an input (e.g., TIM1_CH1) in input capture mode and I properly set the input capture filter (IC1F) to remove noise of the input. Also, I need to detect both edges...

enable css?

I dont understand why this is a option for the mux clock selector. css is a great feature so i didnt find reasons to not enabling.In which cases i should not enable it?
