SPI data transfer is not working when using registers to initialize the SPI unit

I used this function to initialize and setup STM32H743IIT6 uC to work with SPI in master mode:void InitSPI(void) { RCC->APB2ENR=0x00102000; //Enabling SPI45 clock (default: rcc_pclk2=25MHz) SPI4->CFG1=0x30070007; //Baud rate = SPI clock / 16 = 1....

Measuring capacitance STM32L0-Disco

I'm trying to measure capacitance with my STM32L053-DiscoI'm using ADC and one output pin to charge the capacitor. I tried measuring time it takes for capacitor to charge to 62.3%.The problem that I'm facing is that the values that I'm getting from A...

Periodic Interrupt Timer with dynamic period set (programmatically) not being generated

Im in the process of configuring a STM32L432KC to talk with an AFBR-S50 sensor. This sensor needs a periodic interrupt to trigger measurements periodically. In the example they are using a timer with down counting direction to generate the interrupt ...

Hello, I want to use FMC with an adc AD7606. I don't know yet how FMC works; so my question is how i can read fmc_data ? can i consider fmc data bus as simple gpios and read them with Gpio_ReadPin?

STM32G070 as the alternative to STM32G081

ST has confirmed that STM32G070 uses same silicon as STM32G081, thus we're considering use it as the alternative to STM32G081 due to availability problems.STM32G070 lacks BOR feature and CEC hw block acc. to datasheet but we have proven by trial that...

spi in STM32H7

SPI in stm32h7 (stm32h743iitx in slave mode) don't work, receive wrong values.how I make spi to work correctly in stm32H7? its not clear at allthanks,

Are there any errors associated with the CAN Controller on the STM32F205ZGT6 MCU which could explain the CAN bus packet failures when the ambient temperature is increased to 40°C?

Hi,I wonder if you can help us? In one of our projects we are using the STM32F205ZGT6 Microcontroller and specifically we are using the CAN bus. The problem is that when we increase the ambient temperature around the MCU to approximately 38°C to 40°C...
