Interfacing with I2C does not work in STM32F100xx Value line Discovery?Please help

Hi all,I want to use the I2C of my STM32F100xx Low/Medium density value line Discovery board but without using STM32cube IDE because i want to learn the basic register initialization and each step necessary so that i can port it to any IDE but i am u...

Can I interface 10 SRAMs using FMC controller and external address decoder for generating chip select signals.

I need to interface 10 SRAMs (1024 x 16). With existing FMC controller I can interface only 4 so I am planning to use address line decoder for generating chip select signals. My main concern is whether I would need to use external buffers & transceiv...

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....
