Story

Spresense is a compact development board based on Sony’s power-efficient multicore microprocessor CXD5602 with built-in GPS and high-resolution audio capabilities. It allows developers to create IoT applications in a very short time and is supported by the Arduino IDE as well as the more advanced NuttX based SDK.

This is a simple project using Arduino IDE to start with Spresense development board. By the end of this project, you will be able to use Spresense Arduino Library Getting Started Guide to achieve:

Install the USB to serial drivers to connect the Dev board to your computer
Install Spresense board package into the Arduino IDE
Install Spresense loader and libraries
Build and upload the LED sketch ( copy and paste the example code from below)
Flash the Onboard LEDs on Spresense board
Finish your first program on Spresense dev board!

Note: You might need to press the Reset switch in order to start the execution.

The Spresense main board has 4 LEDs: LED0, LED1, LED2, and LED3. To control the LEDs, configure the LED as an output using pinMode()and call digitalWrite(). Please refer to sample code below.

For more information on the Spresense, see the following:

void setup() {
    pinMode(LED0, OUTPUT);
    pinMode(LED1, OUTPUT);
    pinMode(LED2, OUTPUT);
    pinMode(LED3, OUTPUT);
}

void loop() {
    digitalWrite(LED0, HIGH);
    delay(100);
    digitalWrite(LED1, HIGH);
    delay(100);
    digitalWrite(LED2, HIGH);
    delay(100);
    digitalWrite(LED3, HIGH);
    delay(1000);

    digitalWrite(LED0, LOW);
    delay(100);
    digitalWrite(LED1, LOW);
    delay(100);
    digitalWrite(LED2, LOW);
    delay(100);
    digitalWrite(LED3, LOW);
    delay(1000);
}
