標(biāo)題: 賽元SC92F725x單片機(jī)控制直流馬達(dá) 源程序與原理圖
原理圖如下：

功能：第一次按鍵后，馬達(dá)開(kāi)始工作；第二次按鍵則馬達(dá)停止。如只按一次，馬達(dá)工作30秒后休息5分鐘，并以此循環(huán)工作。
馬達(dá)工作時(shí)有LED指示。

單片機(jī)源程序如下:
#include "INC/SC92F725x_C.H"

sbit LED = P2^1;
sbit KEY = P2^0;
sbit MOTOR = P2^7;

//#define LED P21
//#define KEY P20
//#define MOTOR P27

unsigned char T0RH;
unsigned char T0RL;
unsigned char MotorOnTime;
unsigned int MotorOffTime;

bit KeyActionNumber;
bit Active;

void KeyAction();

            {
                     flag5ms = 0;
                     KeyScan();
                     KeyDriver();
            }

            if (Active)                   //啟動(dòng)狀態(tài)
            {

                                    {

賽元下載需要專(zhuān)用燒錄器，還是可以用SUB轉(zhuǎn)TTL或IIC呢
