JOY-IT® DIGISPARK MICROCONTROLLER
26 x 12 mm sized microcontroller
1. GENERAL INFORMATION
Dear customer,
Thank you for purchasing our product. In the following are information
which you should note before commissiong. Whenever you have unfore-
seeable problems do not hesitate to contact us.

2. PREPARING THE INSTALLATION
If the Arduino-Soware is not installed on your systems, please download
the soware with the following link and install it.
https://www.arduino.cc/en/Main/Soware
As the next step, please download the Digispark drivers here.
For computers with Windows 7 or older:
During the boot process, repeatedly press the key that leads to the BIOS (e.g.
F2, F8, F10 or Del). In the next menu, please choose the option Disable driver
signature enforcement.
For computers with Windows 8 or newer:
Click the On/O button. Keep holding the Shi key and click on restart.
In the next menu, choose Troubleshoot → Advanced Options →
Startup Settings →Restart
Aer restarting, please install the previously downloaded driver.
Next, as seen in the next images, open up the Arduino conguration and
insert the following URL to the Additional Boards Manager URL:
http://digistump.com/package_digistump_index.json

If you haven‘t already installed, please install the Digistump AVR Board
library from the Boardmanager.
Now you need to change your Arduino conguration to the
Digispark (Default—16.5 MHz) board

The Arduino IDE is now ready to use with your Digispark. Please do not
connect your Digispark to your computer until the program is asking you to
connect it. This prompt does not appear until code transmission has been
initiated.
3. CONNECTING THE DEVICE
The Digispark can be easily connected to your computer via USB. For the
casual usage, if you don‘t want to power your Digispark by USB, you can
connect a power supply of 5V to the +5V connection or a power supply of
7-35V to the VIN connection. Further devices or components can be
connected to the integrated PINs.
You can see a detailed overview of the pin assignment in the picture below:
4. PROGRAMMING PIN P5
The Pin P5 of our Digispark is predened as Reset-Pin because it is needed
to initialise the bootloader. Without additional conguration, the Pin P5 is
not useable like the other Pins.
The bootloader is already installed when you receive your Digispark. From
this time, the Reset-Pin is no longer needed and can be overwritten.
You can skip this step if you don‘t need the Pin P5. Otherwise you can
enable the functions of the Pin with the following steps.

Warning! An Arduino Uno is needed to congurate the Pin P5.
Open up your Arduino IDE and open the preinstalled ArduinoISP example
(Files → Examples → ArduinoISP) and transfer it to your Arduino Uno.
Watch out that you, if you have already transfered something to your
Digispark, to choose the right board-conguration.
Aer you transfered the code, note the port where your Arduino is
connected to.
You can see the used port under Tools → Port.
Next, connect an 10uF capacitor to the RESET and the GROUND Pin of your
Arduino Uno. Warning! The capacitor is necessary! Do not skip this step!
Now connect your Digispark to your Arduino Uno as seen in the next image
or in the table.

To edit your Arduino Digispark by command-line, you need the AVRDude
programm. Therefore, please download the WinAV Tool from this website.
https://sourceforge.net/projects/winavr/?source=typ_redirect
Aer you have installed the programm, open up the command prompt
and enter the following commands:
In our case, our Arduino Uno was connected to the port COM3. If your
Arduino Uno is connected to another port, please repleace the specic
port in the commands.
avrdude -P COM3 -b 19200 -c avrisp -p attiny85 -n
avrdude -P COM3 -b 19200 -p attiny85 -c avrisp -U hfuse:w:0x5F:m
This is how the output should look like:
avrdude: please dene PAGEL and BS2 signals in the conguration le for part ATtiny85
avrdude: AVR device initialized and ready to accept instructions

The Pin P5 of your Digispark should now be ready to use.

5. TRANSFER OF EXAMPLE CODE
The following example code is for your rst setup and to test the basic
functionality of the Digispark. The integrated LED will keep switching on and
o.
Please transfer the code to your Digispark. Do not connect your Digispark to
your computer until you are asked to.
void setup() {
//Initialisation of digital PIN
pinMode(0, OUTPUT); //LED on Model B
pinMode(1, OUTPUT); //LED on Model A or Pro
}
void loop() {
digitalWrite(0, HIGH); //turns on LED
digitalWrite(1, HIGH);
delay(1000); //waits a second
digitalWrite(0, LOW); //turns o LED
digitalWrite(1, LOW);
delay(1000); //waits a second
}
