二、驱动程序

#include "led.h" void led_init(void) { 
    GPIO_InitTypeDef GPIO_InitStructure; RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOC|RCC_AHB1Periph_GPIOD|RCC_AHB1Periph_GPIOE, ENABLE); GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0; GPIO_InitStructure.GPIO_Mode = GPIO_Mode_OUT; GPIO_InitStructure.GPIO_OType = GPIO_OType_PP; GPIO_InitStructure.GPIO_Speed = GPIO_Speed_100MHz; GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_UP; GPIO_Init(GPIOC, &GPIO_InitStructure); GPIO_InitStructure.GPIO_Pin = GPIO_Pin_13; GPIO_Init(GPIOD, &GPIO_InitStructure); GPIO_InitStructure.GPIO_Pin = GPIO_Pin_6; GPIO_Init(GPIOE, &GPIO_InitStructure); GPIO_SetBits(GPIOC,GPIO_Pin_0); GPIO_SetBits(GPIOD,GPIO_Pin_13); GPIO_SetBits(GPIOE,GPIO_Pin_6); } void led_delay(u8 i) { 
    while(i>0) i--; } void led_write_data(u8 data) { 
    u8 i; for(i=0;i<8;i++) { 
    led_clk=0; if(data&0x01) led_dio=1; else led_dio=0; data>>=1; led_delay(2); led_clk=1; } } void led_show_data(u8 *showData) { 
    led_stb=0; led_delay(2); led_write_data(0x00); //设置数据命令 led_stb=1; led_delay(2); led_stb=0; led_delay(2); led_write_data(0x40); //设置数据命令 led_stb=1; led_delay(2); led_stb=0; led_delay(2); led_write_data(0xc0); //设置显示地址 led_write_data(showData[0]); //设置显示数据 led_write_data(0X00); //设置显示数据 led_write_data(showData[1]); //设置显示数据 led_write_data(0X00); //设置显示数据 led_write_data(showData[2]); //设置显示数据 led_write_data(0X00); //设置显示数据 led_write_data(showData[3]); //设置显示数据 led_stb=1; led_delay(2); led_stb=0; led_delay(2); led_write_data(LED_ON|LED_BRIGHTNESS_3); //设置显示控制命令 led_stb=1; led_delay(2); }
