Setting AD reference voltage
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
4. Terminal will display relative AD conversion value. By default, the displayed conversion value
is come from Pin AD0 on TLC1543 ﴾Pin T_A0 on ARPI600﴿.
5. Connect the jumpers T_A0 to A0, then the Pin A0 on Arduino interface can sever as an AD
conversion pin, as shows.

Configuring as other AD pins
1. If you want to display the conversion value from other AD pins on TLC1543, please enter the
terminal and edit the file tlc1543.c:
sudonanotlc1543.c
Find out the following line:
re=ADCSelChannel(0);
Modify the “0” in the line into the number corresponding to other AD pin ﴾For
