Slider and param.asInt();

Need Help With My Project
1

I want to use a slider set to range 0-10 and want to use that value for a PWM output. Can I do it as I do below to get 0-255 PWM value? I guess there is no param.asByte();

BLYNK_WRITE(V1)
{
PWM1_value = param.asInt();
analogWrite(PWM1, PWM1_value*2.55);
}

you could use the map function:
