In this exercise we will write code for a clock displayed on the LCD screen in the following structure:

$$ First line in the display HH:MM:SS $($hours$,$ minutes, seconds$)$

$$ Second line clock running $23$:$59$:$59$

$$ The one second delay must be created using timer $0$ or timer $1$

which are scheduled according to an internal clock

$$ An initial value of the clock is obtained through a matrix of buttons. assembly programming with PIC$16$F$877$ microprocessor $,$i work in MPLAB IDE v$8\mathrm{.}92$
