Puzzling operation / error with DAC and DMA on STM32F334K8 and STM32F334C8

I'm running into something very odd and wondering if anyone has any insight! I'm developing an audio project, and have implemented double buffering using HAL_DAC_ConvCpltCallbackCh1 and HAL_DAC_ConvHalfCpltCallbackCh1. I started developing this on an...

Hello, I have a STM32F446 and I'm using the STM32CubeIDE to program it. I'm reading data from a pressure sensor and would like to save that data in a .txt (text). But I can't find a way to do it. Can someone help me?

Enter 11 bit CANStandard ID in hex format from Serial Terminal using STM32f407

hi all,i am trying to do CAN Communication using STM32f407 and transceiver using Cube MX and Cube IDE. Now i have given default value for CANTxHandletypedef Txheader.StdID = 0x321. As a next step i need to add this STDID value by entering through Ser...

HI I'm using stm32h753. I'm wondering how I can get access to user SRAM and declare an array there.

I already have a STM32H735G-DK board for the workshop on 25th March.

Change Pin mode from analog to digital in run time. See my code below..

I want to use pin to work as output pin for some time and then Analog pin for some time.how can I change the mode of pin in run time. GPIO_InitTypeDef GPIO_InitStruct = {0}; ADC_ChannelConfTypeDef sConfig = {0};   HAL_GPIO_WritePin(GPIOC, GPIO_PIN_...

There is a need to interact with the 3-pin MediaLB bus.

Hey!There is a need to interact with the 3-pin MediaLB bus.I cannot penetrate into it.How the data exchange takes place, what conditions must be observed, how the request and return frame is formed.Perhaps there are examples of working with the bus o...

SPI modes unclear

Hi everyone,I am working with the SPI in slave mode on an STM32G071 and having some trouble with the different SPI modes. I set both CPOL and CPHA to 0 during initialization: SPI_InitStruct.TransferDirection = LL_SPI_FULL_DUPLEX; SPI_InitStruct.Mode...

I ordered the board from the distributor

What is the default value for PLLON ? If it is 0, should I put a while(PLLRDY =1）?

I have an application running on HSE as system clock..and I set the multiplexer to select HSE, totally not using PLLbtw, should I put any configuration to my PLL? such as PLLON =0, and while(PLLRDY==1) , to “properly configure�? the unused PLL?Or sho...
