WIZnet / Servo_HelloWorld-WIZwiki-W7500

Servo_HelloWorld Example for WIZwiki-W7500

Dependencies:   Servo mbed-src

Fork of Servo_HelloWorld by Simon Ford

Prerequisite

This example is for servo motor test using digital I/O(PWM).

To implement this function, you need a Platform board, network Interface board.

  • WIZwiki-W7500 from WIZnet (Platform board and Ethernet I/F board)

Software

Init GPIO

Servo myservo(D14);

Set data to Servo

    for(float p=0; p<1.0; p += 0.1) {
        myservo = p;
        wait(0.2);
    }

Caution

When wiring, be careful (GND, VCC)
