Hi,

Start looking board description and select pins for PWM: https://os.mbed.com/platforms/ST-Nucleo-F401RE/ Then look at this PWM example: https://os.mbed.com/docs/mbed-os/v5.14/apis/pwmout.html#pwmout-hello-world The example have PWM output LED1 PwmOut led(LED1); You can use any your board PWM pins (PA_0, PA_1, PB_1 ...) PwmOut pwmout(PA_0);

Regards, Pekka
