4.2 Functional Description
4.2.1 Character LCD Module
The kit has a character LCD module, which goes into the character LCD header, P8. The LCD runs
on a 5-V supply and can function regardless of the voltage on which PSoC is powered. There is a
zero-ohm resistor setting available on the LCD section making it possible to convert it to a 3.3-V
LCD. The variable resistor R2 is a contrast potentiometer. It is used to control the LCD contrast.
