STM32F103 minimum system

Overview

test program

Download the program to the minimum system and let B0 connect to an LED test module. If the light turns on, there is no problem.

#include "stm32f10x.h"

#define LED_PORT GPIOB

#define LED_PORT_RCC RCC_APB2Periph_GPIOB

int main()

{

GPIO_InitTypeDef GPIO_InitStructure;

RCC_APB2PeriphClockCmd(LED_PORT_RCC,ENABLE);

GPIO_InitStructure.GPIO_Pin=LED_PIN;

GPIO_InitStructure.GPIO_Mode=GPIO_Mode_Out_PP;

GPIO_InitStructure.GPIO_Speed=GPIO_Speed_50MHz;

GPIO_Init(LED_PORT,&GPIO_InitStructure);

GPIO_SetBits(LED_PORT,LED_PIN);

while(1)

{

GPIO_ResetBits(LED_PORT,GPIO_Pin_0);

}

A "bloody" lesson: Xilinx FPGA daisy chain
This article mainly restores an "accident" scene, and the specific causes need further analysis. Chips in distress: 1 Xilinx FPGA XC5VSX95T, 1 PROM XCF32P, 2 PROM XCF08P, and a pirated Xilinx Platform

What is a stepper motor and how does it work?
The best answer is that the stepper motor is an actuator that converts electrical pulses into angular displacement. When the stepper driver receives a pulse signal, it drives the stepper motor to rota

High level input pin, becomes low after FPGA is programmed!
The motherboard provides a high-level signal, 3.3V, to the daughterboard. 1) After power-on, the daughter board is plugged into the mother board, and the mother board output port A is 3.3V 2) After po
