Jumper JP1 is used to enable/disable resetting the micro-controller when a terminal connection is made to the FTDI breakout board. The 5V supplied by the FTDI breakout board on pin 3 provide power to the micro-controller. In order to transfer data to the FTDI breakout board, pin 2 of the micro-controller is connected to the TX pin of the FTDI breakout board. This configuration uses the internal 8 MHZ clock to drive the micro-controller. Figure 2, contains the schematic diagram of the minimum configuration needed to run an ATTiny85. Let’s begin by configuring the development board. Figure 1, contains a list of supported micro-controllers.įigure 1 – List of Supported Libraries and micro-controllers Hardware Configuration

An ATTiny85 assembled on a breadboard or from a development board such as the one provided by Tinkerlog.Īlthough, I will use an ATTiny85, the instructions applies to any of the ATTiny micro-controller for which ATE provides a compiled Arduino core library.

If you are creative and do not have access to a FTDI Breakout board, you can remove the ATMega328 chip from an Uno board and use the serial communication capabilities already included in the board as a substitute for the FTDI Breakout board. I will use FTDI Basic Breakout from SparkFun to allow the ATTiny85 to send serial information to a terminal. FTDI Breakout Board – The FTDI Basic Breakout from SparkFun or the FTDI Friend + extras from Adafruit will do the job.If you have an Arduino based ATTiny programmer, that is also fine.

An ISP programmer – I will use AVRISP-MKII and AVR Dragon to demonstrate deploying code with either programmer.

Arduino Template Express (ATE) 1.0.2 or greater.

In order to follow this tutorial, you will need the following:

This post will show you how to setup a development board with the ATTiny85 micro-controller and enable it with serial communication capabilities and the ability to use the Arduino Core libraries. The goal of this post is to demonstrate how to use Arduino Template Express (ATE) to deploy the Arduino Core libraries to the ATTiny family of micro-controllers. Simple projects can take advantage of the ATTiny family of micro-controllers. The Arduino core libraries provide a well defined structure for developing code with the different micro-contollers it supports, but not every project requires the power provided by the ATMega 328 or 2560 chips.
