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 ...
There are multiple alternating functions for one peripherals. Why and what is the difference?
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...
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 (...
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 = ...
I want to use DMA on my stm32h7 board, but i can find which channel is used for what protocol ect.
In Atollic, I imported the GPIO example (Blink) which compiled.Trying to Run or Debug in Atollic an IP address is requested. But the board is connected via USB. I have not found no option to flas via USB.
Our application needs 32KByte of storage. Since the STM32F105RC has 256 Kbyte of flash, we want to make use of this instead of external EEPROM. The EEPROM emulation driver uses to two pages, each of 2kbyte and switches between them. However, I need 3...
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...
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...
