interfacing ultrasonic distance sensor ascii pic microcontroller

LCD initializations in 8051 C programming words What is the logic behind the serial communication As in, how long should the SIG send out pulses and what should the delay be These statements are used to tell the compiler that a 16X2 LCD is connected to the above defined pins and the LCD display is accessed using Lcd_ etc functions . Please go to this link to do this in 8051 using keil c RB is used instead

of PORT register and TRIS itself a register. TRIS register is used to set the direction of each pins of that port while PORT register is used to set the status of each pin of that port . Compiler needs these registers during Building process, since LCD can be connected to any of the pins of the microcontroller. Please try it yourself. arduino has all the required built in libraries so just replace the functions used in this program. to arduino functions. it will work. I already have ultrasonic sensor with echo and trigger pins instead of SIG pin. Can i know how micropic program should be changed according to echo and trigger pins. I think. when you provide trigger signal it sends an ultrasonic burst and gives echo signal when the ultrasonic burst receives back . So to calculate distance you should use the equation Distance = time * velocity where velocity is a constant. how does the sensor send the data. i mean in what format. say the distance is 123. 4 cm, then ll it send the ASCII of 123. 4 separately. like ASCII of 4, then. `, then ASCII of 3 etc.
