STM32 MCUs Products

I want to develop a C program on the STM32F303 board that uses the SPI interface where the microcontroller is the master and the L3GD20 gyroscope is the slave: I want to perform a transmission to ask the gyroscope to provide me with the x, y, z coordinate

Considering that the gyroscope's chip select is the PE3 pin, how should I do this? The program below doesn't work#include <stm32f30x.h>void GPIO_Config();void SPI_Config();uint8_t L3GD20_Read(uint8_t reg);void L3GD20_Write(uint8_t reg, uint8_t data);...

STM32F767ZI : I2C2 hangs after few cycles of operation (With FreeRTOS)

I'm using I2C2 engine of the STM32F767ZI MCU on PF0 & PF1 pins as master to communicate with 4 slaves at 75khz. The operation is not using Interrupt on tx/rx or DMA and with FreeRTOS environmentSCL and SDA are pulled up on board with 4.99K.The pollin...

STM32U5 ADC1 bulb sampling multiple channels

Hello,I am using ADC1 on STM32U5 to sample two channels periodically using the DMA and a TIM6 trigger. I am doing this in bulb mode since I would like for the ADC capacitor to charge for the entire duration.I had thought that the ADC would sample th...

I can't debug the file I want, how can I make the file I select debug without there being another file?

Hello, I have had a problem and it is that I make a simple program, in this case the blinking of the led of the "NUCLEO-F401RE" board and I use the gpio that comes by default. The point is that when I try to debug main.c, another file is opened (whic...

F746 DMA from sdram to SPI

Is it possible to set transfer from sdram to SPI. I have set all necessary MPU regions and FMC is configured properly. When I use this with LTDC, it works fine.(not using standard DMA for that).But, when I try to send from 0xC0000000 to SPI, DMA1.str...

Memory flash issue - read status register getting 0xff

Hi Experts,I'm working with the MCU "STM32F427VIT6" and the flash memory "GD25B16ETIGR" and I have a problem when I try to read the "read status register (05h)" I get 0xFF. However I know I have no problem on the SPI connection because I can read the...

Resolved! Quick question. Does somebody know how long the STM32F407 family will still be made?

HAL_SPI_ERROR_DMA

Hi, I am using stm32f769Ni evk for a project. Here I am interfacing stm32 with a wifi module using spi dma . The communication fails during reception with HAL_SPI_ERROR_DMA after /* Enable the Tx DMA Stream/Channel */ if (HAL_OK != HAL_DMA_Start_IT(...

UDP Data Lost Issue

Hi,We're building our system based on STM32F407 with AZure Threadx + NetxDUO. One of the scenarios is as below:1) One 250 HZ task is responsible for sampling on 6 sensors connecting to 3 I2C.2) One UDP thread is receiving command from PC with 250HZ.3...

Can one use the same .hex file to program both the STM32F446RET6 and STM32F446RCT6?

The STM32F446RET6 and STM32F446RCT6 are similar except for Flash size. Is it possible to create a .hex file that programs the RE version that could program both chips using the ST-Link V2?
