PwmOut_HelloWorld Example for WIZwiki-W7500

Dependencies:   mbed-src

Fork of PwmOut_HelloWorld by Mbed

Prerequisite

This example is for PWM test using digital I/O. To implement this function, you need a Platform board.

Below are what we used.

  • WIZwiki-W7500 from WIZnet (Platform board)

Hardware Configuration

WIZwiki-W7500 Pin map

pin map

Software

Init GPIO

    PwmOut led(LED1);

Set PWM

    led.period(4.0f);      // 4 second period
    led.write(0.50f);      // 50% duty cycle, relative to period
