ST team, can you share memory performance (bandwidth) between:1) The M4 core and SRAM memory on an unloaded system?2) A DMA channel doing memory to memory move?3) A DMA channel writing to a peripheral register from memory?Or put another way, how many...
Everytime to debug a program cubeIDE always downloads the program to mcu first no matter the program had not been modified since last download, is it possible to seting the IDE only downloads the program when the program has changed?
Hello,I am using RTC Wakeup timer in STM32F469NIH6 processor. Low level access is using HAL code.I's is configured withRTC.CR.WCKSEL = 0x3RTC.WTR.WUT = 1EXTI.IMR.MR22 is setEXTI.RSTR.M22 is set.It generates RTC Wakeup Interrupt ~122.09usec. interva...
Hello!I was opening a file and trying to read from a specific index of a file on my SD card. I used the following code:FIL fHandle_filename_file; char SDFileName[256] = "filename_1234.BIN"; res = f_open(&fHandle_filename_file, SDFileName, FA_OPEN_...
My ADC1_Data Register is null. I can't understand why it is. Can u help me?#include "main.h" #include "SysClockConf.h" uint16_t values[256]; // MY CLOCK IS 170 MHz." // STM32G431 // READ_BIT() Fonksiyonu void GPIO_Config(){ RCC->AHB2ENR |= RCC_AHB2E...
I am using STM32H743I used uart's DMACheck whether data has been received through this functionBut there is no data in the buffer. Why the hell is this happening?And, of course, I changed the linker start(0x24000000) and end address(0x2407FFFF) of th...
FDCAN1 has a basic parameter 'Clock Divider' set to 'Divide kernal clock by 1'. FDCAN2 does not have this parameter. In library function HAL_FDCAN_INIT(...) there is a statement: /* Check FDCAN instance */ if (hfdcan->Instance == FDCAN1) { /* Confi...
Hi,created some SPI2-slave code running on PB10(SCK), PB12(NSS) and PC3(MOSI) without problem. Needed to move SPI2 to other pins as PB12 will be used by RMII in later design. Decided to use PA12(SCK), PA11(NSS) and PB15(MOSI). SCK is running at 12.28...
Hello to everyone,There are many examples that come with the STM32WL55. Especially LoraWAN examples are very useful. All examples are made to work with TCXO and are not very obvious to those working with XO in code.We made a board with the STM32WL55C...
