The Micro USB RobotDYN compatible development board is an Attiny167 Pro MCU Board that is comparable to the Arduino UNO but is less expensive, more portable, and slightly less powerful. With the aid of a micro USB cable and the Arduino programming software, the board may be programmed. RobotDYN offers a customized version of the Arduino IDE complete with all necessary drivers for Arduino programming. It has 13 digital pins onboard, 11 of which work as ADC pins, I2C, SPI, and what the RobotDYN boards usually lack, which is the UART on the 6, and 7 pins, not to mention the Native USB on the chip, which allows the board to function as a keyboard, mouse, or any HID

Description:

The RobotDYN Pro Micro USB development board is compatible with the Digispark ATTiny167.  you can use the Micro USB cable to connect to the USB interface directly, avoiding the need for a USB to serial interface module. It has 14 digital IO connectors and 10 analog ADC interfaces. The ATTiny167 board is an ultra-small, low-cost, open source, Arduino compatible, USB development platform that is better than an ATtiny85 digispark board in terms of pins, program space, features, and reliability. It supports the entire existing 25+ shield RobotDYN Digispark platform and adds Wi-Fi, Bluetooth, BLE shields, and more, and it has a Micro USB that is ready for all your projects.

Principle of Work:

RobotDYN just like Arduino is Free hardware, anything whose blueprints and specs are available for anybody to copy. This means that RobotDYN which works on the Arduino platform is the framework that any other individual or business can design their own boards, each of which can be unique yet function well when built upon the same framework. Free software is a computer program whose source code is available to anybody, allowing them to use and alter it as they see fit. In order to allow anyone to create apps for boards and Arduino IDE with a variety of utilities, Arduino IDEs the Arduino IDE (Integrated Development Environment) platform. which you can use to program and upload your code (sketch) and do this using an embedded software USB Functionality using the V-BUS library with the help of an embedded bootloader, the uses libraries that can be downloaded online and gives you the ability to program a significant number of sensors and module without even knowing how they really work.

Pinout of the Module:

 

Digital I/O

RobotDYN has 13 digital input/output pins. These pins can be configured as digital input pins to read the logic value (0 or 1). Or used as a digital output pin to drive different modules like LED, relay, etc.

PWM Pins

6 pins can be used as PWM outputs

Analog Pins

The Onboard has 8 analog inputs

GND

Ground pins

AREF

The reference voltage (0-5V) for analog inputs. Used with analogReference(). Configures the reference voltage used for analog input (i.e. the value used as the top of the input range).

I2C Protocol

SDA IIC communication pin

SCL IIC communication pin

UART

on the 6, and 7 pins

USB Connection

The board has a USB interface with software USB functionality based on the V-BUS library which emulates the USB Port even though there is no Serial converter on the board. For connecting to the PC, you need to install the driver

OnBoard LED

There is a built-in LED driven by digital pin 1. When the pin is HIGH value, the LED is on, when the pin is LOW, it's off.

Voltage Regulator

Convert an external input DC7-12V voltage into DC 5V, then switch DC 5V to the processor and other components.

Power Pin 5V

ProvArduino IDEs 5V output voltage

Vin

You can supply an external power input DC7-12V through this pin to the board.

Power LED Indicator

Powering the LED on means that your circuit board is correctly powered on. If LED is off, the connection is wrong.

Applications:

• Industrial machinery controlling systems
• Solar applications
• IOT based applications
• Power supply and charger-based applications
• Weather sensor systems
• Wireless communication applications
• Security based applications
• Medical & health equipment
• Automobile related applications

Circuit:

We will not need any circuit, in this testing code, we will rely on the built-in LED on the 1 pin.

Connecting with First Time

1. Open Arduino IDE

If you haven’t done so already, download Arduino IDE from the software page. 

• Arduino IDE Download

2. Connect the board to your computer

Adding Additional Boards Manager URLs

• From the top menu of the Arduino IDE application, select File → Preferences to open the Preferences dialog box.
• Paste the following in the Additional Boards Manager URLs: box of the Preferences dialog box. If you have multiple URLs then separate them with commas.

http://digistump.com/package_digistump_index.json

• Click the OK button.

 Installing RobotDYN Board Support Package

• In the Arduino IDE, navigate to Tools → Board → Boards Manager… to open the Boards Manager window.
• Type RobotDYN  into the search field at the top of the Boards Manager dialog box window.
• After filtering, Digistump AVR Boards is displayed in the Boards Manager then click on the Install button of the Digistump item in the dialog box, as shown in the image below.
• After clicking the Install button, the package will start installing.
• When the installation completes, click the Close button.

Install the RobotDYN Windows 10 Drivers

• Download the RobotDYN Digistump Drivers for Windows.
• Extract the Digistump.Drivers.zip which we just downloaded.
• Double-click either DPinst64.exe on a 64-bit Windows computer or DPinst.exe on a 32-bit Windows computer to install the RobotDYN drivers.
• Click on the install button when prompted.

• If a dialog box pops up that displays Windows can’t verify the publisher of this driver software, click the Install this driver software anyway button.

3. Select Board

The RobotDYN works a bit differently than some Arduino-compatible products. The RobotDYN programs with a different procedure.

First, from the Tools menu select Board→RobotDYN pro(16Mhz)

(The Tools→Programmer & Tools→Port selection does not matter)

4. Upload a sketch

• Now write some code or open a RobotDYN example. Then click on the upload button (do not connect the Digspark to your PC)
• Hit the upload button. The bottom status box will now ask you to plug in your RobotDYN – at this point, you need to plug it in, or if already plugged then unplug and replug it.

• You’ll see the upload progress and then it will immediately run your code on RobotDYN .

If you unplug the RobotDYN and plug it back in or attach it to another power source there will be a delay of 5 seconds before the code you programmed will run. This 5-second delay is the RobotDYN checking to see if you are trying to program it.

Code:

void setup() {
 pinMode(1, OUTPUT); // On board LED terhubung dengan port 1 attiny167
}
void loop() {
 digitalWrite(1, HIGH);
 delay(200);
 digitalWrite(1, LOW);
 delay(200);
}

Comparisons:

There is no hardware USB module included with the ATtiny167. The V-USB specialized library, however, is what allows it to imitate the USB1.1 protocol. It is really simple to create USB-connected devices such a keyboard, mouse, joystick, and virtual COM port. The RobotDYN also features an LDO regulator that powers the board when a voltage between 7 and 12 V is applied to the VIN pin. The RobotDYN 167 pro features 13 pins as opposed to the RobotDYN 85's 6 pins, making it a more viable option for any project. It also has extra PWM and analog pins accessible. Another reason for RobotDYN 's popularity is that it works with Arduino. but still we can not recommend this board for beginners.
