How to Use MicroView with Programmer: Examples, Pinouts, and Specs

The MicroView is an innovative Arduino-compatible module that integrates a small OLED display with a microcontroller development board. This unique combination allows users to create projects with built-in visual feedback without the need for external display modules. Common applications include simple games, status displays for sensors, and educational tools for learning electronics and programming.

• Microcontroller: ATmega328P
• Operating Voltage: 5V
• Input Voltage (recommended): 3.3-5V
• Digital I/O Pins: 12 (of which 3 provide PWM output)
• Analog Input Pins: 6
• DC Current per I/O Pin: 40 mA
• Flash Memory: 32 KB (ATmega328P) of which 0.5 KB used by bootloader
• SRAM: 2 KB (ATmega328P)
• EEPROM: 1 KB (ATmega328P)
• Clock Speed: 16 MHz
• OLED Display: 64x48 pixels monochrome

1. Powering the MicroView: Connect the VIN pin to a 3.3-5V power supply, or use the USB connection provided by the programmer.
2. Programming the MicroView: Connect the MicroView to your computer using the included programmer. The programmer interfaces with the Arduino IDE for easy code uploading.
3. Using the I/O Pins: Connect sensors, actuators, or other peripherals to the digital and analog pins as required by your project.

• Always disconnect the MicroView from power sources before making or altering connections.
• Use current-limiting resistors with LEDs and other sensitive components to prevent damage.
• Avoid exposing the OLED display to direct sunlight for extended periods to prevent damage.

#include <MicroView.h>

// Initialize the MicroView object
MicroView uView;

void setup() {
  uView.begin(); // Initialize the OLED display
  uView.clear(PAGE); // Clear the screen
  uView.print("Hello, World!"); // Print a message to the screen
  uView.display(); // Refresh the display to show the message
}

void loop() {
  // Main loop code goes here
}

• Display Not Working: Ensure that the MicroView is correctly seated in the programmer and that the programmer is properly connected to your computer.
• Sketch Not Uploading: Check the Arduino IDE's selected board and port. Make sure drivers are installed if necessary.
• Garbled Display: This can happen if the display is not properly initialized. Ensure that uView.begin(); is called in the setup() function.

Q: Can I use the MicroView with a battery? A: Yes, the MicroView can be powered by a battery connected to the VIN pin, as long as the voltage is within the recommended range.

Q: Is the OLED display replaceable? A: The OLED display is not designed to be user-replaceable. Handle the display with care to avoid damage.

Q: How do I clear the display? A: Use uView.clear(PAGE); to clear the display. Remember to call uView.display(); to refresh the screen after clearing.
