==Learn==
*If it's the first time for you to use Raspberry Pi, please make sure the I2C interface is enabled,the following steps will show you how to enable I2C interface
*Type in [sudo raspi-config] set up raspberry pi and prepare to enable i2c interface
<br>[[Image:RTC_tech02.png|700px]]
*select Advanced Options
<br>[[Image:RTC_tech03.png|700px]]
*select I2c
<br>[[Image:RTC_tech04.png|700px]]
*select yes enable I2C
<br>[[Image:RTC_tech05.png|700px]]
*type in [sudo vim.tiny /etc/modules] to open file modules
<br>[[Image:RTC_tech06.png|700px]]
*add i2c-dev device like picture below
<br>[[Image:RTC_tech07.png|700px]]
*install i2c-tools ,type in [sudo apt-get install i2c-tools]
<br>[[Image:RTC_tech08.png|700px]]
*type in [sudo reboot] wait the raspberry pi restart ,Then type in [sudo i2cdetect –y -a 1], if AD-DA Module works ,it should be like picture below
<br>[[Image:Adda tech01.png|700px]]
*Now you can use some command to test this module .Type <code>gpio -x pcf8591:120:0x48 awrite 120 12</code> to lightening the LED. notice: the Jumper cap should be mounted on the port

<br>[[Image:Adda tech02.png|700px]]
*the command<code>gpio -x pcf8591:120:0x48 aread 120</code>can read the ADC input
