我想問ㄧ下前輩因為我現在的ad值進來會ㄧ直改變 所以我現在程式第一筆資料要放在A4第二筆後才放在A2裡
*A4=A2;意思就是*A4接收A2舊的資料 新的資料放入A2 我ㄧ直在測試指標部分好像有問題正在研究中!!不知道前輩能否給ㄧ下建言


//******************************************************
// calculate
//********************************************************
void calculate(int A2,int *A4)
{
int b;
int e,a;
a=1;
b=(A2-*A4);

e=b/a;
if(e>205) //10bit 1v=1023/5=205
{
RB1=0;
}
else
{
RB1=1;
}
*A4=A2;
}

//***************************************
//* Program Main ( ) *
//***************************************
void main(void)
{
int A4, temp,A2;
unsigned int j;
Init_IO();
Init_Adc();
while(1)
{

A2D(); // Get 10-bit A/D result from CH1
A4=temp; /temp is AD value
for(j=1;j<65534;j++)
{
A2=temp;

calculate(A2,&A4);
}
}
}
