Week #2 – RUP Team Roles / First steps with the controller firmware

RUP Team Roles

Our Team only consists of two member, so our Roles will intersect at some points.

However, according to the RUP Terminology, we have taken on the following roles:

Team Member	Roles
Simon König	Project Manager Requirements Specifier Implementer Tool Specialist
Manuel Piroch	Project Manager Requirements Specifier Designer Test Designer Tool Specialist Implementer

You can find links to our project management and GitHub projects on the right side of this blog page.

First steps with the controller firmware

This week we started testing the individual components of the cube by uploading simple sketches to the Arduino that interfaced the Individual components.
“Sketches” are what the Arduino IDE calls a project you can compile and write to the hardware. it can consist of multiple .ino source files.

After the LEDs, Bluetooth Module and Gyro worked flawlessly we started combining the functions to see how they would work together to get a seamless implementation.

The following sketch controls the color of the LEDs on the cube by numbers sent via a Bluetooth terminal:

/*
   Find the outgoing HC06 COM port in the Bluetooth settings
   connect to the port using putty
   tap 1 and 0 into the console to test LEDs
*/

#include <FastLED.h>
#include <SoftwareSerial.h>

#define LED_PIN    9
#define NUM_LEDS   6
#define BRIGHTNESS 8
#define LED_TYPE   WS2812B
#define COLOR_ORDER GRB

SoftwareSerial BT(5, 6); // RX, TX
int ledpin = 13; // LED on D13 will show blink on / off
int BluetoothData; // the data sent from computer
CRGB leds[NUM_LEDS];

void setup()
{
  FastLED.addLeds<LED_TYPE, LED_PIN, COLOR_ORDER>(leds, NUM_LEDS).setCorrection( TypicalLEDStrip );
  FastLED.setBrightness(  BRIGHTNESS );

  BT.begin(57600);
  BT.println("Bluetooth On please press 1 or 0 blink LED ..");
  pinMode(ledpin, OUTPUT);
}

void loop()
{
  // main loop
  if (BT.available())
  {
    BluetoothData = BT.read();
    CRGB color = CRGB::Black;
    
    switch (BluetoothData)
    {
      case '1':
      color = CRGB::White;
      break;
      case '2':
      color = CRGB::Red;
      break;
      case '3':
      color = CRGB::Green;
      break;
      case '4':
      color = CRGB::Blue;
      break;
    }

    for ( int i = 0; i < NUM_LEDS; i++) {
        leds[i] = color;
      }
      FastLED.show();
    delay(100);// prepare for next data ...
  }
}

We will now continue to extend the firmware to enable two-way communication between the cube and the computer.
This will then serve as our data link for the gyro sensor data and possible player interactions within the game.
