Interfacing is the process of connecting devices together so that they can exchange the information and that proves to be easier to write the programs. Here we are using keyboard and LCD display as input and output devices along with the micro-controller.

However to perform the operation we need an input device to enter the data and in turn output device displays the results of the operation. Interfacing is one of the important concepts in micro-controller 8051 because the micro-controller is a CPU that can perform some operation on a data and gives the output. Printf("\n 8051 unsigned int size : %d",sizeof(unsigned int)) Printf("\n 8051 int size : %d",sizeof(int)) Printf("\n 8051 unchar size : %d",sizeof(unsigned char)) Printf("\n 8051 char size : %d",sizeof(char)) What will be printed as the result of the operation below Writing the subroutine for the timer for time required and clear timer value TRx at the end of subroutine. Setting the timer run bit to start the timer. Enabling the IE registers and corresponding timer bit in it. Choosing and loading the initial values of TLx and THx for appropriate modes. Timer 0 and Timer 1 interrupts are generated by the timer register bits TF0 and TF1 Selecting the timer by configuring TMOD register and its mode of operation. Its mainly using for choosing timer and counter.It has Two 16 bit registers namely TH0, TL0 and TH1, TL1.First, you need IAR version 10.30 download from the link.
