i can see the 2 pwm are added pwm1:0 , pwm1: 1
using cd pwm1:0 i am assigning the duty cycle , period and enable
if i rebooted the BBB means this configurations are erasing, why i am not
getting??
using config-pin -l P9.14
config-pin P9.14 pwm
i am setting pin for pwm as p9.14
in hardware wise i am connecting 1 external led providing 1 connection from
P9.14 and other end to ground.
but led should glow based on pwm duty-cycle, but here the LED not all
glowing ???
