I tested the delay with the LED and the delay works. I than added the sonar() function and after 1 second the LED doesnt go back on. So the error has to be in the sonar function.
thanks to mgate and again after re-reading the data sheet I have added a 50 ms delay after it captures the distance data. But it's still not looping.
Again i think it might be that I'm using timer0mode1 gate controlled (for the time counter for the sonar) and now timer1mode1 for the 50 ms...
Ok so I got it working as it should. Only thing is now it's not always reading. I have it in the while(1) loop but every time i want to recapture new distance data I have to hit the reset button on the 8051. In other words it's not always reading data, only when the program starts. attached...
Hi I'm having trouble interfacing a sonar sensor and the 8051. I've searched around online and read the datasheet and have some code. I understand what needs to be done to implement the sensor but having a hard time getting it to work. It's a 3 pin sonar sensor. I have the signal pin connected...
I want to implement a sequential circuit using verilog that functions as a 4-bit universal shift register. The shift register will have two inputs that specifies which function the register will perform: 0 0- No change, 0 1-Shift Right, 1 0- Rotate Left, 1 1- Parallel Load
If the shift...
