在一个STM32点亮LED的程序中,部分代码如下:void GPIO_Configuration(void){GPIO_InitTypeDef GPIO_InitStru
void gpio_configuration(int pin, int mode, int pull_up_down) 其中,pin代表要配置的GPIO引脚编号,mode表示引脚的工作模式,pull_up_down表示上下拉电阻的设置。 3.引脚编号 GPIO引脚通常是通过一个数字进行标识,具体的编号规则要根据硬件平台和硬件设计而定。不同的开发板或芯片可能会有不同的GPIO引脚编号方式,...
voidconfigure_gpio() { int pin_num = 5; GPIO引脚编号为5 int mode = INPUT;配置为输入模式 int additional_settings = INTERRUPT_ENABLE;启用中断功能 gpio_configuration(pin_num, mode, additional_settings); } 在这个示例中,我们将GPIO引脚设定为输入模式,并启用中断功能。这意味着当引脚的电平发生变化时...
