Experiment 2

part1:Shift Operations
------
ISIS :
RA0:switch with VCC then 10K to gnd
RC0:res=330 with led to gnd
RD0 to RD7 :connect 8 wires to
LED-Bargraph(pin 9&10 out)then to
RESpack(pin 1 to gnd and rest connected)
--------
code :
#include <p18F4520.h>
#include <xc.h>
#pragma config OSC=INTIO67,WDT=OFF,MCLRE=OFF
#include <delays.h>
#define xmitpin PORTCbits.RC0

part2:Receive Serial (in) Bit 0 First
to bring the data serially one bit at a
time via the RB0 pin. Place the byte in
port D. The LSB (D0) should come in first.

ISIS:
RA0:switch with VCC then 10K to gnd
RB0:(led with res=220 with gnd)
parallel with (switch with VCC then 10k to gnd)
RD0 to RD7 :connected with
LED-Bargraph (pin9&10 out)
to RESPACk(pin 1 to gnd)

part 3:Both Transmit and
Receive Systems

ISIS: 2pic
pic1:{transmit}
RA0:switch to VCC then 10K
to gnd and with pic2(RA0).
RC0:res=330 to led to gnd
and to pic2(RB0)
RD0 to RD7 :connect 8 wires to
LED-Bargraph(pin 9&10 out)then to
RESpack(pin 1 to gnd and rest connected)
---
pic2:{recieve}
RA0:above
RB0:above
RD0 to RD7 :connect 8 wires to
LED-Bargraph(pin 9&10 out)then to
RESpack(pin 1 to gnd and rest connected)

part4:7segment dispaly
common cathode

ISIS:
RA0:10K to VCC then switch to gnd
RA1:res=330 to led to gnd
RA2:res=330 to led to gnd
RB0 to RB7 :connected to 8 pins
in (7segment dispaly respictively)
and there is pin in 7 segment dispaly
below it connected to gnd.
