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
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
