made attempt at code and isis
#include <reg52.h>
#define upper 22
#define lower 17
#define ON 1
#define OFF 2
unsigned char a2d_val;
sbit fan = P2^0;
sbit heater = P2^1;
sbit start_con = P3^0;
sbit eoc = P3^7;
void delay_50 (void);
void main (void)
{
eoc = 1;
P1 = 0xFF;
fan = heater = OFF;
while (1)
{
start_con = 1;
start_con = 0;
while (eoc == 0)
{
}
a2d_val = P1;
if (a2d_val > upper)
{
fan = ON;
heater = OFF;
}
else if (a2d_val<lower)
{
fan = OFF;
heater = ON;
}
else
{
fan = heater = OFF;
}
delay_50();
}
}
void delay_50 (void)
{
TMOD = 0x01;
TL0 = 0x60;
TH0 = 0x3c;
TF0 = 0;
TR0 = 1;
while (TF0 == 0)
{
}
TR0 = 0;
}
code worked i think but problems building it
