Re: What is the default, and maximum PWM frequencies on the Galileo?

Greetings joaocandre

The fastest frequency we were able to get was 13.97kHz with this commands:

echo -n "3" > /sys/class/pwm/pwmchip0/export
echo -n "1" > /sys/class/pwm/pwmchip0/pwm3/enable
echo -n "62500" > /sys/class/pwm/pwmchip0/pwm3/period

echo -n "31250" > /sys/class/pwm/pwmchip0/pwm3/duty_cycle

Remember you can also use this commands in the IDE with the function system(), in case you prefer using the Arduino side. The usage of this function would be like this, for example

system("echo 3 >/sys/class/pwm/pwmchip0/export");
