SAI with blocking mode
Hello, I have this code // Initialiser le bloc A fresult= HAL_SAI_Init(&hsai_BlockA1); if (fresult != HAL_OK) { return HAL_ERROR; } // Initialiser le bloc B fresult= HAL_SAI_Init(&hsai_BlockB1); if (fresult != HAL_OK) { r...

How to configure DMA to change PWM frequency (led strip controlling through one-wire protocol)?
Hi! I am configuring DMA to generate a PWM signal to control addressable LEDs with an STM32563VGTx MCU.My issue arises when generating the PWM signal using DMA. When calling the "HAL_TIM_PWM_Start_DMA" function, it executes without any errors, and th...
Resolved! Debugging using vscode + ST-Link + cortex-debug with external flash (qspi)
VSCode is gaining in popularity at work and so I had a requirement to use it as the development platform for an ST mcu based project. I have very little experience with vscode and as I was unable to find an answer to my problem I thought that I would...
STM32F4 StdPeriph GPIO_MODE
i use nucleo-f446ze learning how to use STM32F4 stdperiph，but in STM32F4XX_GPIO.h，GPIO_MODE only have 4 mode，GPIO_Mode_IN = 0x00, /*!< GPIO Input Mode */GPIO_Mode_OUT = 0x01, /*!< GPIO Output Mode */GPIO_Mode_AF = 0x02, /*!< GPIO Alternate function M...
Resolved! Failing to read useful data from ADC of STM32f411
Hello,upfront, it might be an incredibly dumb problem on my behalf as I am fairly new to this.For a couple days now I have been trying to read out the voltage through the onboard ADC configured for 12 bits but all I am getting back are values in a si...
How to use external SDRAM as dynamic data memory in M4 core in STM32H747I-DISCO board?
Hi community,I am using STM32H747I-DISCO board and I configured external SDRAM as dynamic data memory in M7 core by calling the SystemInit_ExtMemCtl() function in SystemInit() function, it is working fine but when I tried with the M4 SystemInit_Ext...
Problems dividing HCLK - STM32L433RCTxP
Hi, everyone.When implementing a sort of delay function using Timer2 to have a more precise time control, while putting the MCU in power-saving mode, I noticed that the division performed to the APB1/2 clocks does not correspond to what's programmed....
Problems with clock prescalers and saleae on an STM32H563ZI nucleo board when using SPI
Hello, we are using the saleale logic 8 to read data transfer between an STM32 MCU and an IC through SPI (ADS8166 ADC).The CLK frequency is 1.5 for the SPI configuration with a prescaler of 2 so at the end we have CLK of 750 kHz. For some reason SO...
Stlink v3 set IAR 8.50 error "Failed to load Flash loader"
I am currently working on a project that requires the use of IAT EWARM 8.50. When I compile this project for an STM32H745XI MCU and try to flash/debug I get the "Failed to load Flash loader" error. On the flash console I get this output:C:\Program Fi...
ST-Link V2 error No target connected
Posted on July 24, 2015 at 16:37Hello everyone.I am using a custom board with STM32F030C8 on it and ST-Link V2 for programming and debugging on keil MDK v5.14.It worked fine and i was able to burn and debug the firmware. Yesterday i programmed an ex...
