這是我第一次用合泰單片機寫程序，里面用到定時器和ADC，分享一下。

單片機源程序如下:

#include "HT66F002.h"
#define MS1000HSPINIT 250 //高速模式
unsigned char ms_1000; //定義1/31S
unsigned int ms1000set; //定義1S
unsigned char ms_10000;
unsigned int minute1;
unsigned int minute360;
unsigned char chargedetect;
unsigned char chargemode;
unsigned char levelstore;
//設備的實際開關機狀態位，0為關機，1為開機
unsigned char SYS_ON_OFF_SATE;
//燈亮度設置函數
void LightSet(unsigned char setvalue)
{
_stm0al=setvalue; _stm0ah=0;
}
//AD轉換函數
unsigned int AD_CaiJi() //unsigned char Channel
{
unsigned int AD_Data;
AD_Data=0;
//開啟轉換
_start = 0;
_start = 1;
_start = 0;
while(_adbz==1); //輪詢轉換
AD_Data = _sadoh;
AD_Data <<=4;
AD_Data += (_sadol>>4);
return AD_Data;
}
void main()
{
//adc參數定義
unsigned int adcx;
unsigned char ADC_Sate;
unsigned char ADC_Sate1=0;
//adc數據存儲變量
unsigned int adcx1;
unsigned int adcx2;
unsigned int adcx3;
unsigned int adcx4;
unsigned int adcx5;
//I/O口初始化設置
_papu = 0b11011011; //上拉設置，1為上拉，0為不上拉
_pac = 0b11111011; //IO口方向設置，0為輸出，1為輸入
//引腳功能設置
_pas4=1; //PA2=STP0
_pas6=1; //_pas6和_pas7用來設置PA5 功能選擇,選擇為ADC的通道AN3
_pas7=1;

LightSet(0);
