I paid someone and she came up with a solution using STM32F103 and claims that it works for wav files using PWM and low pass filter with a digital attenuator. It didn't, and 1 year on I am still looking for the right MCU and the right solutionUM1642...
Hello,I'm using SDMMC to save ADC DMA data to an SD card on Nucleo H723ZG. I made some tests and got distorted results. Then I realized a problem, sampling speed is too slow when I use fatfs writing commands. What might be the problem?I use a 64K buf...
HI, I m trying to send a 16 bit word using SPI HAL to a SPI external interface driver. SPI is configured as:-Transmission master-16bit data TX-MSB first.This driver requires first address of the register and then the content to be received. I created...

HiIn main.c I have got these lines: osMailQDef (object_pool_q, 10, MEM_memberTypeDef); // Declare mail queue osMailQId (object_pool_q_id); object_pool_q_id = osMailCreate(osMailQ(object_pool_q), NULL);in another file in my therad I want to access obj...
I'm running the SBSFU on a STM32H7 where I can succesful upload a new application and it is starting. The application is running on an external flash.The question is, can I simply change the clock system settings to the applications need at startup o...
Hi,I am developing a sensor board that includes an STM32U575CGTx MCU, an IMU, a microSD card slot, USB, and a battery (rough schematic attached). If you have a better suggestion for the MCU, please feel free to suggest it. The data logging rate is re...
Dear everyone, I am using an STM32F429ZI Nucleo board and using the ADC_RegularConversion_DMA example on STMCubeIDE 1.10.1I must say on a first point of fiew, the example seems to work fine, there are some analog data in the variable: __IO uint32_t u...
I'm trying to make use of the HAL_UARTEx_ReceiveToIdle_DMA() functionality.So far no reaction on an IDLE event. The corresponding HAL_UARTEx_RxEventCallbackgets called when a certain amount of bytes has been received, but not on an IDLE event.The dev...
