MicroView Arduino Library - Main Page


MicroView Arduino Library Documentation

Developed by Geek Ammo Pty Ltd based on Arduino and other Open Source libraries.

Description

Arduino library for MicroView.

Required Libraries

  1. Time.h NOTE: Only required when using clock/time functions. For example the MicroViewDemo in the example folder.

Installation

  1. Change directory to Arduino's main directory
  2. cd libraries
  3. mkdir MicroView
  4. cd MicroView
  5. git clone https://github.com/geekammo/MicroView-Arduino-Library.git .
  6. Start Arduino IDE.
  7. MicroView example is located at, File—>Example—>MicroView—>MicroViewDemo

### Example 1 - Hello World!


#include <MicroView.h>
void setup() {
    uView.begin();
}
void loop() {
    uView.print("HelloWorld");
    uView.display();        // display current page buffer
}

### Example 2 - Basic Drawing


#include <MicroView.h>
void setup() {
    uView.begin();
    uView.clear(PAGE);      // clear the page buffer
}
void loop() {
    uView.line(0,0,64,48);
    uView.circle(32,24,10);
    uView.rect(10,10,20,20);
    uView.pixel(50,5);
    uView.setCursor(0,40);
    uView.print(" MicroView");
    uView.display();        // display current page buffer
}

### Example 3 - Widgets


#include <MicroView.h>
MicroViewWidget *widget,*widget2;
void setup() {
    uView.begin();
    uView.clear(PAGE);
    widget= new MicroViewGauge(32,30,0,100);  // draw Gauge widget at x=32,y=30,min=0, max=100
    widget2= new MicroViewSlider(0,0,0,100);  // draw Slider widget at x=0,y=0,min=0, max=100
}
void loop() {
    for(int i=0; i<=100;i++) {
        widget->setValue(i);    // give a value to widget
        widget2->setValue(i);
        uView.display();        // display current page buffer
    }
}

### Example 4 - Communication


#include <MicroView.h>
void setup() {
    uView.begin();
    uView.clear(PAGE);
    Serial.begin(115200);   // user decide the baud rate
}
void loop() {
    uView.checkComm();
}
