Hello Experts,

I have a board (with some opamps) which is connected to BBB (P8_13), and 
want to get 0-10V from that board.

With this code, I'm getting 7V DC from my external board, so how can I 
write these values '*duty_cycle'* and '*period*' ??
*b.analogWrite('P8_13', 0.7, 2000.0, printStatus);*

>From this entry, I have '*duty_cycle'* and '*period*' , now what value I 
need to write here for the above analogWrite code ?
*/sys/class/pwm/pwmchip4/pwm1*
