Resolved! Same codebase across multiple projects
HelloI'm using STM32cubeide with STM32LI have several applications that are based on the same code base.What are the good solution(s) to handle this common code with stm32cubeide?I can consider several solutions, one application = one project or one ...
Which guidelines should I trust choosing crystal for oscillator: AN4488 or AN2867?
AN4488 goes like:Why 15 pF is a maximum value? It came out of nowhere. At the same time AN2867:Emmmm...So I am confused. What should I do now? Never use 12.5 pF crystal or use it and do the calculations in accordance with AN2867 to get accurate value...
STM32F4 FLASH MEMORY CHECKSUM SELF CHECKING
Hi, @Community member @TDK I am working on the STM32F4 to implement the FLASH MEMORY CHECKSUM SELF CHECKING to determine if data and program in FLASH have been corrupted and if so not to run the user program.Any information regarding implementation...
Resolved! Generating a delay using "wasted" instructions
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...
Resolved! Strange DAC behaviour on STM32H743VIT6 Hi to community! I have a strange problem with DAC. Whatever settings (buffer on/off, dma mode, data format or allignment, speed, etc) i am not getting simple output results that are expected. Thanks in advance!
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,...
Urgent help: How to use CAN bus interface to perform stm32f042k6 DFU?
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. ...
Resolved! Bad jitter on LSE over ~0.1s time scales
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...
How to proceed with programming Nucleo-64 using C++
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...
