2. Establish working directory cd ~ mkdir cpu_show
3. Download source code to /home/pi/cpu_show through SFTP
4. Compile source code cd ~ /cpu_show cc -o cpushow pcd8544_rpi.c PCD8544.c -L/usr/local/lib -lwiringPi
5. Final execution and result-check sudo ./cpushow
6. Knowledge on Contrast Modification
7. There are differences in contrast between each LCD, so if your found content displayed is too dark or too light, you'll need to modify contrast variables of source code pcd8544_rpi.c, then recompile the source code and check the final result as well as corresponding changes!
