LCD Character Display – I2C-bus Interface

Demonstration setup for LCD character display connected to NI myRIO MXP. The mode jumpers set for I2C-bus serial communications.
In this project, students learn the principles of operation and applications of an LCD screen, as well as the principles of the I2C communication protocol. Students use myRIO and LabVIEW to display the states of the myRIO embedded accelerometer and push button on the LCD screen. In these activities, students follow steps to demonstrate correct operation of the LCD Screen, watch videos involving theory, and participate in a short activity after each video.
