Hi,

I am new to 8051 microcontroller and have not done any professional course regarding this.

I wanted to make obsatcle avoidance robot for may baby. So i wrote the programme. But it does not calculate the distance correctly. I have posted the codes here. But please i am sorry that i did not mention comment on LCD display.

Later i just wantt to run the robot in 4 PWM speeds according to the obstacle distance.
If you you possible please help on me.
Thanking you.

You might want to look at USComplete. It is defined as "1". It needs to be a bit at some location that is set and cleared. For example: "setb p1.0" sets bit 0 of PORT 1. There does'nt appear to be a location for the bit that is being set, cleared and tested.
