I am trying to change the system clock on my STM32F410RB using register programming. I have setup an SPI protocol to an external DAC IC which needs a minimum of 100ns (10MHz) clock period. The SPI allows for a maximum of 8MHz (fPCLK/2) at default clo...
Hello ,We are encountering an issue with the USART_DMA interrupt method on the STM32G070CBT6 microcontroller. The problem is that data is only received after performing a hardware reset. We expect the data to be received continuously without needing ...
I'm trying to get a simple UART hello world program to work. It just transmits a buffer once per second. I've enabled UART2, enabled the interrupt, and configured the baud rate, parity, and word length. But when I open minicom I don't see anything. I...
Hello,I am facing constant difficulties in connecting to my Nucleo H723ZG Boards.Almost every time I try to update the ST-Link via STMCube32IDE, the compilation stops half-way through the process and throws an error (see image)I have tried:swapping c...
Hello I am working with an STM32G474RET6, using Timer 3 in one-pulse mode with an external trigger.Below is my Timer 3 initialization code:static void MX_TIM3_Init(void){/* USER CODE BEGIN TIM3_Init 0 *//* USER CODE END TIM3_Init 0 */TIM_ClockConfig...
Hello,We have a device that runs an stm32g0. I have a bootloader at the beginning of the flash and then 2 pages for config and the rest of the flash for the firmware. The bootloader basically checks if the two config pages are OK and then starts the ...
Hello,I'm currently working in a project with the Nucleo-L476RG board. Basically, I have a MEMS microphone (AN-000048) connected to the board. The microphone (I pretend to work in stereo mode) sends PDM data and I use the DFSDM module get the microp...
Hi there,this is my first post here. So be gentle with me ;)I been working on a project with STM32H757XIH6 for some time now, but without any success. This is already my 2nd prototype and costed me quite some $$ since it had to be a 8 layer PCB. The ...
Hi everyone,1, What are the acceptable buffer sizes for the DFSDM PDM mic configuration, give me some examples?2, Can I use ( int32_t buffer[4000] ) for the PDM buffer?3, How do I sync different sensors with the DFSDM PDM mic?
Hello,I'm a hobbyist and I'm working on a USB to 4xI2S (8 channels using the SAIs) using a stm32H7 MCU. I have a proof of concept working on a stm32F7 discovery board. I'm starting to look at the dedicated board.I understand that the USB peripheral n...
