 [[File:ks0213-1.png|500px|frameless|thumb]] 

==Introduction==
There's no AD/DA function on the Raspberry Pi GPIO interface, this may trouble you in the Pi development. However, it won't be a problem anymore. The RPI GPIO-PCF8591 Shield allows you to add high-precision AD/DA functions to the Raspberry Pi. 
The PCF8591 features four-8-bit analog to digital converters and a single 8-bit digital to analog converter.This will operate through the I2C interface on the Raspberry Pi. 

==Connection Diagram ==
Plug it directly into Raspberry Pi to start your works as shown in below figure.
 [[File:ks0213-2.png|500px|frameless|thumb]] 

==Sample Code==
<pre>
DA(Digital to Analog) Source Code：
#include <wiringPi.h>
#include <pcf8591.h>
#include <stdio.h>

#define Address 0x48
#define BASE 64 //DA Output
#define A0 BASE+0
#define A1 BASE+1
#define A2 BASE+2
#define A3 BASE+3

int main(void)
{
unsigned char value;
wiringPiSetup();
pcf8591Setup(BASE,Address); //configuration pcf8591

while(1)
{
analogWrite(BASE,value); //write the value output on AOUT interface
printf("AOUT:%d\n",value); //print that value
delay(50);
}
}

AD(Analog to Digital) Source Code：
#include <wiringPi.h>
#include <pcf8591.h>
#include <stdio.h>

#define Address 0x48 //pcf8591 address
#define BASE 64
#define A0 BASE+0 //A0 input
#define A1 BASE+1 //A1 input
#define A2 BASE+2 //A2 input
#define A3 BASE+3 //A3 input
int main(void)
{
unsigned char value;
wiringPiSetup();
pcf8591Setup(BASE,Address); //configurationpcf8591

while(1)
{
value=analogRead(A0); // read A0 value
printf("A0:%d\n",value); // print A0 value
delay(100);
}
}
</pre>

==Program Writing==
===1.Install Wiringpi Library===
Wiring Pi is a library. WiringPi supports analog reading and writing, and while there is no native analog hardware on a Pi by default, modules are provided so other A/D and D/A devices can be implemented relatively easily. We will provide a Wiringpi installation package or click on this
URL: https://projects.drogon.net/raspberry-pi/wiringpi/download-and-install/ (it should open in a new page) to download the latest version. This will download a .tar file with a name like wiringPi-b0a60c3.tar. Then copy the file and put it into the raspberry pi file as shown in below figure:
 [[File:ks0213-3.png|500px|frameless|thumb]] 

Type in this command to unzip the source code and install: 
tar xfz wiringPi-98bcb20.tar.gz 
cd wiringPi-98bcb20 
./build 
Note that the actual file name will be different (may not be 98bcb20) – you will have to check the name and adjust accordingly. Here is the interface after installing WiringPi as shown in below figure. 
 [[File:ks0213-4.png|500px|frameless|thumb]] 

WirtingPi includes a set of gpio commands to control the GPIO pins of the Raspberry Pi. Type in the command to check the installation:
gpio -v 
gpio readall 
The interface as shown in below figure means complete installation.
 [[File:ks0213-5.png|500px|frameless|thumb]] 

===2.Enable I2C Utility==
The I2C bus allows multiple devices to be connected to your Raspberry Pi. Before using I2C it needs to be configured. Run this command: sudo raspi-config and follow the prompts to install I2C. Now complete the following steps : 
Select “9 Advanced Options” 
Select “A6 I2C” 
The screen will ask if you want the ARM I2C interface to be enabled : 
Select “Yes” 
Select “Ok” 
Select “Finish” to return to the command line 
When you next reboot the I2C module will be loaded. 

===3.Programming==
Copy the file pcf8591 provided by us and put it into your pi directory through winSCP. Next , type this command: cd pcf8591 to go inside the pcf8591 folder. Then type this command: make to make an executable file. This means this is the file we run to launch the program. 
Finally type this: sudo ./TTP229 to launch the program. 

==Result==
DA source code makes AOUT interface output 0-5V voltage; the pi will prints digital value among 0-255 on the terminal after reading out voltage set by AD source code.
