- #include "timer.h"
- #include "flash.h"
- #include "key.h"
- #include "dac.h"
- #include "adc.h"
- #define FLASH_SAVE_ADDR 0X0800C004 //设置FLASH 保存地址(必须为偶数，且所在扇区,要大于本代码所占用到的扇区.
- int main(void)
- {
-
- u8 key=0;
- NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2);//设置系统中断优先级分组2
- delay_init(168); //初始化延时函数
- uart_init(115200); //初始化纯诓ㄌ芈饰?15200
- Adc_Init();
- Dac1_Init();
- LED_Init(); //初始化LED
- TIM2_config();
- TIM3_config();
- KEY_Init(); //按键初始化
- while(1)
- {
- key=KEY_Scan(0);
- if(key==KEY0_PRES) //KEY1按下,写入STM32 FLASH
- {
- LED0=0; //LED相关参数配置，点亮LED3
- TIM_Cmd(TIM3,ENABLE);
- }
- if(key==WKUP_PRES) //KEY2按下,读取字符床⑾允?
- {
- LED1=0;
- TIM_Cmd(TIM2,ENABLE);
-
- }
