串口调速小车1

1. 让小车动起来

智能小车1-智能小车的初认识_void motor-CSDN博客

接线

B-1A -- PB0

B-1B -- PB1

A-1A -- PB2

A-1B -- PB10

 CubeMx

1.常规配置

SYS->Debug->Serial Wire

RCC->High Speed Clock(HSE)->Crystal/Ceramic Resonator

时钟树HSE、PLLCLK打开，HCLK设置成72MHz

打开GPIO口

可以在这修改（重定义）GPIO口名称，相应的在main.h文件中修改

 

 2.生成代码

keil

main.c

int main(void)
{
 
 
  while (1)
  {
 
		Motor_front();
		HAL_Delay(1000);
		Motor_back();
		HAL_Delay(1000);
		Motor_Left();
		HAL_Delay(1000);
		Motor_Right();
		HAL_Delay(1000);
		Motor_Stop();
		HAL_Delay(1000);
		
  }
}

main.h
