I need to confirm my understanding. Say that my STM32H7 SPI is setup as Slave and that it processes the incoming SPI data byte per byte in interruption. It is very likely to happen that the SPI throughput is faster than the SPI interrupt handler dura...
Hello everyone i am using CAN bus to connect two stm32 boards, i would like to know does anyone of you know how does the CAN memory works? is it DMA or what exactly? i couldn't manage to find anyuthing on the internet and i really hope one of you can...
hello everyone, i would like to know how can i transfer data from CAN Bus to DMA memory on stm32f4 board on HAL Library? also i want to make sure that the CAN access memory is it DMA or somethign else?can you please explain to me how? or if you hav...
Hello, I try to make an UART communication between Nucleo STM32F030RE and a STM32F030K6 mounted on a custom pcb.sends from NUCLEO to STM32F030K6 is OKReceive from STM32F030K6 is ok sends from STM32F030K6 to NUCLEO is OK (i can check it and decode tha...
In order to investigate the SPI issues on my own setup (based on STM32H743 Nucleos) I gave a try to the SPI example project in STM32Cube 1.4 (SPI_FullDuplex_ComIT). Compiled and debugged with Keil 5.28.In this example project Slave and Master exchang...
Hello, with a STM32F7508-DK board, all examples using SDRAM have the sysclk to 200MHz, therefore the FMC clock to 100MHz.I am trying to enable sysclk = 216MHz, and FMC = 108MHz, so I followed the SDRAM user manual, and configured the following settin...
HiI am working with a STM32L496G_Discovery board and Cube IDEI am having problems with the external ram. I have called BSP_SRAM_Init();and defined an array in that ram spacefloat testInput[TEST_LENGTH_SAMPLES] __attribute__((section("._myvars")));In ...
Hi,I am trying to comunicate raspberry pi (master) and stm32f4 (slave) trough spi with dma. I am using HAL_SPI_TransmitReceive_DMA. The comunication seem is working fine but time to time (when 10/8/6data has been receive/trasnmit +-) my stm32 trasmi...
