LXTerminal will display the time clocked by PCF8563 which may be different from
the Raspbian)
5)
Enter LXTerminal, and input:
hwclock -w (Write the time of the Raspbian into PCF8563)

Configuring Pin A0 to Pin AD
1)
Please make sure you have installed relative libraries (refer to the Section 2.2:
Installing relative libraries).
2)
Set the jumpers to select reference voltage:
Connect REF to 5V, which means the AD conversion reference voltage is 5V
(connecting to 5V is a default setting).
Connect REF to 3V3, which means the AD conversion reference voltage is
3.3V.
Notices: REF can only be connected to one reference voltage at a time.

3)
Copy the file program/AD_TLC1543 in to Raspbian. Then, enter the folder
AD_TLC1543, and execute the following code under the terminal:
sudo make
sudo ./tlc1543
