What is SPI vs SPI MSP for STM32

Posted on March 28, 2016 at 17:23I am new to the STM32 product line and starting to write SPI code using the STM32cubeMX module. I note in the cube drivers manual that they provide both HAL_SPI_Init and HAL_SPI_Mspinit.  Looking through the web and ...

Fast UART Receive Interrupt with FIFO mode

Hi all,I need to install a communication between 2 STM32H743 units (on one board) with maximum speed (10 MBit) on UART mode and I need to check incoming characters to detect Linefeeds etc. The problem is that with FIFO mode enabled (Threshold 1/8) in...

USART in Synchronous Slave Mode with Interrupt not working

Hi all,I try to install a synchronous USART communication between 2 x STM32H743, one is the (transmitting only ) Master the other is the (receiving only) Slave. When transferring data via Polling everything seems to work well.But when using HAL_USART...

Problem with data transfer between 2 MCUs via I2C

Hello, dear collegues!Please help me with I2C!I use I2C to transfer data between 2 controllers: STM32F051C8T6(Master) and STM32F100C8T6 (Slave). When I use laboratory power supply, it works without some problems. But when I use external power supply ...

STM32f407G-DISC1 Technical Documents

Hi, i'm currently working with the MB997D version of the mentioned Development Kit on the caption. My main goal is working with the lis3dsh sensor on this board and then apply it to my own board, i've tried and accomplished the work with that sensor,...

STM32F746G-DISCO internal RTC not working

Hello,I am using STM32F746G-DISCO board for internal RTC. And using Keil u5 IDEI enabled the Internal RTC clock in CubeMX, set the time and date.And am using HAL_RTC_GetTime - API in while loop for reading sTime and sDate.I am monitoring sTime and sD...

I need help to configure MDMA on stm32H7

I need some help on configuring a transfer from external SDRAM buffer and LCD buffer (via FMC with Intel 8080 like interface).I've adopted the [MDMA_RepeatBlock_Rotation] as refernce example from the CUBE_H7 package.In this project for STM32H743I_EVA...

A PROBLEM WITH STM32F730 USING CMSIS_DSP

I had tried to compile a project with only a 64-point fft. But it turned out to be like"fft\fft.axf: Error: L6406E: No space in execution regions with .ANY selector matching arm_common_tables.o(.constdata)."I cannot believe it as I can run fft on bas...
