Quick_Start_Guide_RL78G15_Fast_Prototyping_Board

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 7 and newer.”
      • At the time this Quick Start Guide was created, operation had been confirmed with version “Arduino IDE 1.8.19.”

Launching Arduino IDE

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

Specifying the Board Manager File for the RL78/G15 Fast Prototyping Board

• Select File → Preferences and specify the following for Additional Boards Manager URLs:
  • https://raw.githubusercontent.com/renesas/Arduino/master/hardware/package_index_rl78g15_fpb_p20_bundled.json
    • 

Using Boards Manager to Install Tools

• Select Tools → Boards: “Arduino Uno” → Boards Manager….
  • 
    • In the text entry box to the right of Type All, enter RL78 and perform a search, then click the Install button.
      • 
• The compiler, Arduino library for RL78/G15 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.

• Enter the following source code into the source code editor (sketch_date tab) of Arduino IDE.

void setup() {
  // put your setup code here, to run once:
  pinMode(4,OUTPUT);
}

void loop() {
  // put your main code here, to run repeatedly:
  digitalWrite(4,HIGH);
  delay(1000);
  digitalWrite(4,LOW);
  delay(1000);
}

Hardware Setup

• Connect the PC to the RL78/G15 Fast Prototyping Board using a USB cable.

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

  • 

• Configure the COM port number setting in Arduino IDE.

  • 

• Select the board in Arduino IDE.

  • Select Tools → Boards: “Arduino Uno”→ Renesas RL78/G15 → RL78-G15 Fast Prototyping Board 64Pin.
    • 

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.
