Installing Arduino IDE

• https://www.arduino.cc/en/software
  • Download the version of Arduino IDE that matches the type of PC you are using.
    • The example below describes the procedure for “Windows Win 10 and newer, 64 bits”
      • At the time this Quick Start Guide was created, operation had been confirmed with version “Arduino IDE 2.1.0”

Launching Arduino IDE

• Double-click the icon on the desktop to launch Arduino IDE.

Specifying the Board Manager File for the Fast Prototyping Board

• Select File → Preferences and specify the following for Additional Boards Manager URLs:
  • For RL78/G24 : https://raw.githubusercontent.com/renesas/Arduino/master/hardware/package_renesas_rl78g24_fpb_index.json
  • For RL78/G16 : https://raw.githubusercontent.com/renesas/Arduino/master/hardware/package_renesas_rl78g16_fpb_index.json

Using Boards Manager to Install Tools

• Select Tools → Board → Boards Manager….
  • 
    • In the text entry box, enter RL78 and perform a search, then click the Install button.
      • 
• The compiler, Arduino library for Fast Prototyping Board, and board programming tool are downloaded and installed in Arduino IDE.

Writing a sketch to make an LED flash at 1.0-second intervals.

• Select File → Sketch example → 01.Basics → Blink. The following code is printed.
• 

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);  // turn the LED on (HIGH is the voltage level)
  delay(1000);                      // wait for a second
  digitalWrite(LED_BUILTIN, LOW);   // turn the LED off by making the voltage LOW
  delay(1000);                      // wait for a second
}

Hardware Setup

• Connect the PC to the RL78/G23-64p Fast Prototyping Board using a USB cable.

• Use Device Manager to confirm which COM port number has been recognized.

  • If you don't see the COM port, open-circuit J13 and reconnect USB.

• Configure the COM port number setting in Arduino IDE.

  • 

• Select the board in Arduino IDE.

  • Select Tools → Boards → Select board to use.
    • 

Compiling, Uploading, and Running Sketch

• In Arduino IDE, select Sketch → Upload to compile and upload the sketch.
  • 
• When the upload completes, the sketch runs and the LED flashes at 1.0-second intervals.
