2) First click theWiringOP icon to open the Wiringop App<br><br>

3) Then click the '''PWM_TEST''' button to enter the PWM test interface at the main interface of WiringOP<br><br>

4) The corresponding address corresponding to the PWM15 is '''febf0030'''. The right side of PWMCHIP0 is exactly the '''febf0030.pwm'''. If the displayed base address is wrong, please click the drop -down option to select other PWMCHIP until the '''febf0030''' is displayed on the right.<br><br>

5) Then confirm the PWM cycle. The default configuration is '''50000ns''', and the PWM frequency is '''20KHz'''. You can modify it by yourself.Click on the button to export '''PWM15'''<br><br>

6) Then drag the drag below to change the PWM duty ratio, and then check the enable to output PWM<br><br>
