Changing filter and channel properties during the run

Hi,I'm using DFSDM on NUCLEO-L476RG, the DFSDM configured as follows:static void MX_DFSDM1_Init(void) {   /* USER CODE BEGIN DFSDM1_Init 0 */   /* USER CODE END DFSDM1_Init 0 */   /* USER CODE BEGIN DFSDM1_Init 1 */   /* USER CODE END DFSDM1_...

Problems setting the frequency of the PWM for the DMA for ADC on the Nucleo-64 F446RE

I am trying to build a guitar pedal using the nucleo-64 F446RE. And I'm trying to configure my CODEC using DMA. Furthermore, figure 1 below shows my CODEC output, the green sine wave (500Hz/1Vpp) is the input and the yellow sine wave is the output. N...

cannot debug, throwing the error

I accidently clicked on device configuration tool code generation icon i believe and i am now unable to run the code. I am getting these bunch of errors. How do i solve this problem?

I'm getting some weird I2C behavior with a GY-87 (MPU6050, HMC5883L, and BMP180 sensor)

Whats happening is when I probe the WHO_AM_I register on the MPU6050 I am getting a weird response of 0x72 instead of 0x68. This does not happen on a generic MPU6050 only board. Any ideas? the code in question is simply "HAL_I2C_Mem_Read (&hi2c1, MPU...

FMC Nor Flash XIP with STM32H7

Hi I have a custom STM32H743 board with FMC nor flash M29W128GH70ZS6, and I want to run code on this FMC nor flash.I noticed there is anexample project in STM32Cube_FW_H7_V1.11.0\Projects\STM32H743I-EVAL\Applications\ExtMem_CodeExecution\ExtMem_Appli...

STM32L562CEU6P locks up and requires power cycle (NRST not working)

I created a development board for an STM32L562CEU6P (P = SMPS part) which contains a 1.2V step down regulator for the externally-provided Vcore, and it also has a USB->serial converter (for various reasons I didn't want to use built-in USB) and an ST...

Hello, the STM32F030C8T6 chip I recently bought has repeatedly reset after the burning program, and can only be burned once. After the first successful burning, after the reset by external keys, the chip reset pin will continue to output triangle waves, r
