VPM buttton 按钮代码 实例 系列之四

1。本实例实用按钮，Button控制LED亮灭。

2。Button自带延迟时间选项，可以填入数值，单位ms。不过注意：输入的是十六进制，再次打开可以看到自动转化为十进制。

3。实例代码如下： 编译环境HT IDE 3000 V7.0

/*
Date : 20091010
For : button drive led
Tool : HT IDE 3000 V7.0
MCU : HT48R50A-1
Fsys : 4MHz
ASM/C: C
VPM : yes
*/
#include "self-HT48R50A-1.h"

#define ledPort _pa //led driving ports
#define ledPortCtrl _pac //led controling
#define swPort _pc0 //switch port
#define swPortCtrl _pcc0 //switch controlling

int iCntButton;
//function
int getSwitchStatus(void);

void main(void)
{
int i;
int swStatus;

ledPortCtrl = 0x00; //output
ledPort = 0xff; //turn off leds
swPortCtrl = 0xff;

//_delay(10000);
swStatus = 1;
while(1)
{
_delay(1000);

swStatus = getSwitchStatus();

if(1 == (swStatus%2))
{
ledPort = ~ledPort; //change led's status
}
}
}
//function
int getSwitchStatus()
{
_pcc = 0xff;

if(0 == _pc0)
{
iCntButton++;
while(0 == swPort)
{
_delay(1000);
}
return 0xff;
}

return 0x00;
}

4。自定义头文件代码如下：
