Overview

IteaduinoTiny.jpg

Iteaduino Tiny is a mini development board based on Attiny85-20 master, which is cheap, compact and easy to use with low power consumption. The mainboard is a derivative board with reference to digispark design, and it supports use of specific Arduino IDE and uses Arduino syntax for programming which is quite convenient.

Software

Let’s take Windows7 operating system as an example, before we use Iteaduino Tiny, we need to install driver for it. First, download the modified Arduino IDE offered by Digispart in the following address: http://sourceforge.net/projects/digistump/files/.

We included Digispart USB driver files in the document, so we can execute the driver file (DigisparkArduino-Win32->DigisparkWindowsDriver->InstallDriver.exe)to install the driver in the system. Keep clicking "Next" till installation of the USB device is completed.

When Iteaduino Tiny is connected to a computer via USB at the first time, the system will find the new device and display installing Digispart bootloader,

Next, you can run DigisparkArduino-Win32Digispark-Arduino-1.0.4arduino.exe, open the modified Arduino IDE, where we can write and compile our codes. During downloading, you need to select the board type, browse and select Tool> Board> Digispark (Tiny Core) in sequence. Then choose Tools> programmer> Digispark.

Because there is no reset pin on Tinny85, before pressing the "upload" button to download codes onto Iteaduino Tiny, you need to unplug the USB cable on Iteaduino Tiny first to disconnect the USB connection. Then, press the "upload" button, after ‘Plug in device now…’ is displayed on IDE window, reconnect the USB cable, and then IDE will download the compiled data onto Iteaduino Tiny. For details about operating procedures, please refer to user manual for Iteaduino Tiny.
