#113739 - 8052 with Polaroid Ultrasonic Sensor |
Hello everyone again! I just wanted to know if this setup is possible. I have an INIT line from the sensor that sends out the signal then when there is a reply, the echo line goes high... i tried to write a simple program in assembly that basically just takes the time it takes on a timer and display it on P1. Im not fully done with the code becuase i know in order to find the distance measured i must take in consideration that im using a 4MHZ crystal so each instruction is 3 micro seconds. The sensor travels at 1.78 m/s per foot, so im going to take the hex number i get from a timer and multiply it by 3/1.78 and that will give me the answer it feet. Anyway, i just wanted to know becuase my program isnt running proprtly.

| Problem? | 01/01/70 00:00 | |
| That's a fast sensor! | 01/01/70 00:00 | |
| Copy paste it in notepad | 01/01/70 00:00 | |
| sry wrong code | 01/01/70 00:00 | |
| And then formatted | 01/01/70 00:00 | |
| At first glance... | 01/01/70 00:00 | |
| im going to switch P3 and P1 | 01/01/70 00:00 | |
| Won't make any difference | 01/01/70 00:00 | |
