LCD Screen

Display text and numerical value on specified line of LCD screen

  • Library:
  • Simulink Coder Support Package for ARM Cortex-based VEX Microcontroller/LCD

Description

The LCD Screen block displays a static label and a value from the block input on the LCD screen. You can also choose to display only the label and not to display the value.

A maximum of 16 characters are displayed for a label or a combination of label and its value. Any output on the LCD screen more than 16 characters is truncated.

For example, if you select only a label to be displayed, the label can have maximum length of 16 characters. If you select a combination of label and its value, the maximum length of the characters displayed for both is 16.

Using this block, select a line on which you want to display the label and value, and then turn the LCD backlight on or off.
