Example Projects
Example Project 1: LCD_Seg_Example1_Battery_Meter
This example project demonstrates the battery charge indicator along with the 14-segment display of
the LCD glass by implementing a battery meter. The battery meter is used to graphically display the
battery charge level; the 14-segment display is used to relay messages related to the battery charge
(full, medium, and low).
Project Description
The potentiometer on the DVK is used to increase and decrease the battery meter on segment LCD.
The four segments (S2, S3, S4, S5, refer
5V) to define the switching on/off of the battery meter. This is accomplished by the Delta-Sigma ADC
count values of PSoC Creator. Based on the battery meter, 'Full', 'Medium', and 'Low' are displayed
on the 14-segment LCD display.
