Hi All,Using an STM32F429 and reading online documentation I have come frequently to this code used for generating delays in Ms if the SYSCLK is 16Mhzvoid delayMs(uint32_t n) { int i; for (; n > 0; n--) for (i = 0; i < 3195; i++) ; }I...
Code is too simple, else is initiated by CubeMx, using latest CubeIde. Board is DevEBox.#define buf_size 512uint16_t data[buf_size]={};for(uint8_t i=0;i<(buf_size/4);i++)data[i]=4095;HAL_TIM_Base_Start(&htim6);HAL_DAC_Start_DMA(&hdac1, DAC_CHANNEL_1,...
MCU - STM32f042k6Stage - Feasibility study to make a proof of concept in 10 working days.My team is using CAN bus interface of stm32f042k6 in a project. As a requirement, we need to see the possibilities of DFU over CAN bus interface of stm32f042k6. ...
In our product, we would like to use the LSE crystal to accurately time a measurement of roughly 0.1 seconds. In this case, we are using an STM32G474 MCU. Using a Nucleo-G474 board for proof-of-concept work, we have found that there is very bad jit...
Hi all,I'm an experienced C++ programmer who happen to start learning embedded programming, with a little stuff, like STM32F411RE Nucleo-64 (the board I'm working on mainly) and a blue-pill alongside breadboard and a bunch of wires. I haven't done mu...
I'm trying to do a periodic ADC capture on 2 channels, triggered by TIM5. ADC should output to memory via DMA, with a DMA interrupt upon each completion to read the data from each scan.So far, the DMA interrupts aren't hitting, and the ADC doesn't ev...

I am trying to receive messages in DMA mode, on a STM32L432KCU. The pins PA2 and PA3 are configured as DMA pins. The baudrate is 115200 and the global interrupt for USART2 is turned on. In the main function, I have the initialization of the periphera...
In STM32U575/585 RM0456 Rev 2 from September 2021, I see the following:"11.4.7 LSE clock...External source (LSE bypass)In this mode, an external clock source must be provided. It can have a frequency of up to 1 MHz."However, in STM32U585xx DS13086 R...
