sonarO = 1; //
5uS delay// or whatever u want to keep
sonarO = 0;// pulse complete L-H-L
//no delay required, prepare your controller for calculating time..
sonarO = 1;//make it i/p pin to read the pulse width

hello! newbie here. i am kind of a guy who hates using ready - made existing libraries, so this helped a lot as i was trying to control and write to a character lcd display. however, i can't figure out how to set the cursor position. for example, i want to set it to the 5th column in the first row, so position 5. so according to the table, i am sending 10000101 on the 8 data lines of the lcd (register select pulled low). the cursor does not move there however. and i cant move the cursor left or right too. is it something wrong that i am doing? thank you.
