Reserve the pins on the Arduino connected to the LCD and used by the library. Reserving prevents other functions from using these pins, giving your library exclusive use of the pins. Send commands, including pin
#Open the Raspberry Pi terminal and run the following commands: wget http://www.airspayce.com/mikem/bcm2835/bcm2835-1.71.tar.gz tar zxvf bcm2835-1.71.tar.gz cd bcm2835-1.71/ sudo ./configure && sudo make && sudo make check && sudo make install # For more information, please refer to...

You can see that all serial port order to control LCD begin with ”$”and end by ”\r\n” when compared with this code,Both of them is corresponding order and parameters,different commands with different parameters. "r" means (the current cursor movement to first line , do not move to...
Depending on the LCD, one of the following commands should be entered: #0.96inch LCD Module sudo ./main 0.96 #1.14inch LCD Module sudo ./main 1.14 #1.28inch LCD Module sudo ./main 1.28 #1.3inch LCD Module sudo ./main 1.3 #1.47inch LCD Module sudo ./main 1.47 #1.54inch LCD Module...

As you see, commands are one-byte values with some parameters. What I did in this library is to convert them into more meaningful functions.Assuming that you have placed the library files in the libraries folder of your Arduino IDE, you can include the header file in your sketch. If you...
