各位大哥，小弟想用STC12单片机实现ad转换，转换完的时候如果结果大于1那就将某一个引脚变为低电平，是不是可以这样写啊：
sbit P00 = P0^0;
sbit P12 = P1^2;
void InitUart();
void InitADC();
void SendData(unsigned char dat);
unsigned char GetADCResult(unsigned char ch);
void Delay(unsigned char n);
void ShowResult(unsigned char ch);
unsigned char ad_result;
void main()
{
InitUart(); //Init UART, use to show ADC result
InitADC(); //Init ADC sfr
while (1)
{
ad_result= GetADCResult(2);
if(ad_result>1)
{
P00=1;
ShowResult(2);
}
else
{
P00=0;
ShowResult(1);
}
}
}
void ShowResult(unsigned char ch)
{
SendData(ch); //Show Channel NO.
SendData(GetADCResult(ch)); //Show ADC high 8-bit result
}
unsigned char GetADCResult(unsigned char ch)
{
ADC_CONTR = ADC_POWER | ADC_SPEEDLL | ch | ADC_START;
_nop_(); //Must wait before inquiry
_nop_();
_nop_();
_nop_();
while (!(ADC_CONTR & ADC_FLAG));//Wait complete flag
ADC_CONTR &= ~ADC_FLAG; //Close ADC
return ADC_RES; //Return ADC result
}
void InitUart()
{
SCON = 0x5a; //8 bit data ,no parity bit
TMOD = 0x20; //T1 as 8-bit auto reload
TH1 = TL1 = -(FOSC/12/32/BAUD); //波特率计算公式晶振/12/32/baud
TR1 = 1; //T1 start running
}
void InitADC()
{
P1ASF = 0xff; //Open 8 channels ADC function
ADC_RES = 0; //Clear previous result
ADC_CONTR = ADC_POWER | ADC_SPEEDLL;
Delay(2); //ADC power-on and delay
}
void SendData(unsigned char dat)
{
while (!TI); //Wait for the previous data is sent
TI = 0; //Clear TI flag
SBUF = dat; //Send current data
}
void Delay(unsigned char n)
{
unsigned char x;
while (n--)
{
x = 5000;
while (x--);
}
}
