In the interrupt of serial port 1, data is output in both serial port 1 and serial port 2. Serial port 1 first sends data, then serial port 2 sends data. After serial port 1 outputs a few frames of data at the beginning, there is no data output, whil...
Hi, I use the core-g431kbt6 which I feed at 10 volts between the Vin pin and the gnd. I would need to connect with the usb via stm Studio to monitor some variables, but when I do the card is reset. Is there any way to avoid this reset?
I am working on custom board STM32F7 MCU project with W25Q256FV quad SPI flash memory and according to the ST 5-Part quad SPI video tutorials, I copied all the necessary sections from public storage QSPI.c & QSPI.h files to my project, but based on m...
Recently a thought popped up when I had a look through interrupt handlers (Using HAL):As Systick handler gets called every millisecond (if not changed to something else) only to increase a counter, doesn't this unnecessarily waste valuable compute ti...
hey,I have a STM32L432 and with putty i can see a sort of serial monitor. It works.....sort of, well i see weird characters. i have the same baud rate and the rest of the settings are dafeault. i have put the code under here.if you have the answer i...
I am using STMF746 controller with my customized board. By mistake I set memory protection unit. When I m trying to connect with STM Utility software, I am getting below error. Can not read memory! Disable Read Out Protection and re...
Hello,Here is my code:#include <stdio.h> #include <string.h> #include "stm32f10x_gpio.h" #include "stm32f10x_rcc.h" void GPIOSYS(void){ GPIO_InitTypeDef GPIOStructure; RCC_APB2PeriphClockCmd(RCC_APB2Periph_AFIO,ENABLE); //GPIO_PinRemapConfi...
I am trying to use the STM32L452RE Nucleo to research an interface to an eMMC device. I have generated a project for this using STM32CubeMX. The eMMC device I am using has its interface voltage connected to 3V3, however, when I look at the CLK output...
Hi,I am working with STM32H743ZII was configuring GPIO output pins and I have to define "speed" which I assume is related to opamp slew rate. But I have a problem with the units, I can choose between "Very high", "High", "Medium", "Low". After readin...
Is it possible to use half-duplex mode and synchronous mode in the USART at the same time?I am trying to use USART with half-duplex mode and synchronous mode.When I refer to RM, it says "the synchronous mode is selected by writing the CLKEN bit in th...
