fxBargraph

Flexible LCD bargraph library for Arduino

Purpose

Bargraph / progress bar library with a variety of display options. Based on I2C LC displays. Uses custom LCD characters for increased resolution, including a super high-res mode. Dynamic custom character defintion allows a very efficient use of the available characeter compared to similar libraries, leaving enough for other usage. The dual bargraph mode enabled display of two independent graph in a single row, making best use of limited display space.

Simple Example

#include <LiquidCrystal_I2C.h>
#include <fxbargraph.h>

LiquidCrystal_I2C lcd;

// display,x,y,width,id,maxvalue
fxBargraph bar(lcd, 0, 0, 16, 0, 1023);

void setup() {
  pinMode(A0, INPUT);
  lcd.begin();
}

void loop() {
  bar.setValue( analogRead(A0) );
}

Features

• Variety of bar styles
• Left-to-Right and Right-to-Left support
• User-defined character for empty space
• Uses only single custom character per graph
• Dynamic customer character definition
• High resolution graphs utilizing every pixel
• Optimized display redraw
• Variant for 2 independent graphs in single row
