I have taken a program for the basic hadyboard analog port and converted
it over to us the expasion board analog ports. The only problem is it
only read the first port. I have tried it on three of my handyboard with
the same result.
I have recheck the lib_hb.lst file to make sure it included everthing
and I beleive it does. I built all three board at the same time so there
could be some bad components but port 16 works. So I believe it is the
code.
Any help would be greatly appreciated.
void main()
{
int i,j,dark,dark1,light[7],t;
i=16;/*used to get values from port 16 and above*/
while(!start_button() + !stop_button())
{
printf("press start button\n");
while(!start_button());
while(start_button());
while(!stop_button())
{
/*printf("press stop button \n");*/
for(j=0;j<7;j++){
for(t=0;t<900;t++){} /*used for debugging values*/
light[j]=_exp_analog(i);
printf("%d %d %d \n",j,light[j],i);
i=i+1;
}
i=16;
dark=0;
dark1=3;
for(j=0;j<7;j++){
if(light[j]>dark){
dark=light[j];
dark1=j;
}
}
printf("%d %d %d\n",dark1,light[dark1],i); /*output the hiest
value*/
}
}
}
