STM32 MCUs Embedded software

Not able to read data from IS25LP128F SPI Flash Memory to the STM32F05 SPI 2 peripheral

It's the first time I'm trying to use the SPI protocol with Flash memory.Write Program function code:void Flash_Write_Data(void){ uint8_t Write_Enable = 0x06; uint8_t Page_Program = 0x02; uint32_t Address = 0x00000000; uint8_t addrLow...

Can USART3 on the STM32F730Z8T6 be used for the ST embedded bootloader? Are there any other specific hardware requirements other than toggling the boot pin to '1' to enter boot ROM .

I've looked at AN2606, it referencess STM32F73xxx but does not specifically list the STM32F730xx under the supported STM32F73xxx parts for the document. I am assuming this is an oversight but I wanted to be sure that USART3 would work and things will...

Hello, I'm using FreeRTOS and I'am wondering if the HAL Driver functions are thread safe. So if I call for example the HAL_I2C_Master_Transmit function from multiple threads, do they interfere with each other, or are they thread safe?

Cheers and thanks a lot.

SPI Flash drive on USB MSC controller

I have a 4MB SPI Flash chip attached to an STM32F105 CPU that I would like to make into a Mass Storage Controller over USB. I made and built a Cube project.At first, I thought I had to modify the functions in user_diskio.c. This did nothing. I the...

in FreeRtos when the semaphore is created it becomes immediately available the osSemaphoreWait function so it is not blocking for the task waiting for the semaphore

CAN setup and filters using HAL

Hi, I have quite extencive experincu using CAN and J1939. In this project I am working on now I will impliment CAN signaling in a STM32F446. My questions:1.CAN_TxHeaderTypeDef.ExtId, shall be used with extended IDs. What will happen if .StdId is also...

I want to send data from my STM32F429 Nucleo-144 to my laptop with Ethernet communication protocol

I'm using eclipse IDE (system workbench).Where i get the demo application and how to build and run on target board ?How to configure IP on PC and target board ?

how to check usb cable is connected with many devices?

hello, i want to check usb cable is connected . below code is ok with one device which is used with stm32L4xx chip.​static int8_t CDC_Init_FS(void){ /* USER CODE BEGIN 3 */  //jeff: check the usb cable connect  if(hUsbDeviceFS.dev_state == USBD_STAT...

Can not configure the HAL_SPI_Receive() funciton to provide 8 clock cycles to the CLK pin.

Hi everyone.I'm working on NUCLEO-F303RE board to acquire mouse sensor displacament data to the MCU to be processed. Mouse sensor has an SPI interface which is 2 wires (CLK and SDIO). So i configured my SPI3 peripheral accordingly on CUBEMX and it wo...

Hello I have a question about echo server(using lwip socket).

What I want to do is create a TCP server that uses stm32f746-disco until the client sends a shutdown command.So, I created an echo server with lwip socket referring to the example, and when I close it, the connection with client ends.I think that if ...
