Resolved! STM32CubeMX generated project files enable "Parallel build" by default?

Nowadays nobody has single core CPU where project is building, so this option should be enabled by default, or configurable in CubeMX.

Maximum reasonable Frequency for TIM2 Frequency counter measurement?

Hello,We're looking at using a STM32F303RE for a project. One of the requirements is being able to measure the frequency of a square wave ranging from 1MHz - 40Mhz. I've been looking at the General-purpose timer cookbook (AN4776) and trying to get...

Resolved! Can I set the heap size to zero?

In my STM32F72xx/3xx project, I'm not allocating memory dynamically, i.e., I'm using neither malloc nor free. And I'm restricting myself to C, with no C++ parts.Is there a reason I shouldn't set the heap size to zero? Do any of the drivers, HAL or ...

Resolved! [Solved] What is the difference between GPIO_AF5_SPI2, GPIO_AF6_SPI2 and GPIO_AF7_SPI2 on the stm32h743zi?

There are multiple alternating functions for one peripherals. Why and what is the difference?

Problem in switching the SYSCLK to MSI in STM32CubeHALv1.7.0

Posted on October 02, 2017 at 10:39Hi, In the HAL_RCC_DeInit function, switching the SYSCLK to MSI only uses this function CLEAR_BIT(RCC->CFGR, RCC_CFG_SW). But, to select MSI as system clock source, I think that it is required to use after that the...

Compile LAPACK (and BLAS) for STM32L452CEU5 (C++)

Hi,I'm trying to use Armadillo (http://arma.sourceforge.net/docs.html) with the above mentioned STM32 MCU.The goal is to use it for the inversion of a dense, symmetric, positive semi-definite Matrix (actually a convariance matrix) with float values (...

Resolved! STM32F407VE USART DMA RECEIVE

Hello everyone, I am a beginner on STM32F4. I want to using DMA for receiving data via USART. But it doesnot work, please help me to solve the problem. Here is my code:void USART2_ConfigDMA(void){ DMA_InitTypeDef DMA_InitStructure; RCC->AHB1ENR = ...

Resolved! [Solved] Where can you find the h7 DMA request map?

I want to use DMA on my stm32h7 board, but i can find which channel is used for what protocol ect.

How to measure quadrature encoder frequency\speed constantly

I'm using F401 that is connected to an A\B encoder and the A\B are routed to TIM2 that is set to work in encoder mode and it is counting the encoder movement as expected.I want to use another timer that will work as TIM2 slave for measuring the encod...

Can two separate QSPI FLASH chips be used simultaneously without using dual memory mode

Hi,Being new to QSPI technique I have to ask for some help to find out if I have misunderstood the whole concept.Our target is to have two QSPI flash memories and run the code from the first one (xip) and use the second one for data storage to be use...
