Hi guys,
I need to control a couple of servos using my Raspberry Pi 3a so I installed Periphery via luarocks. The GPIO code for standard in and outputs works fine however I cant get the PWM system to work. If I add the require as in the code below all is fine until I add Open PWM which gives me an error.
"Opening PWM: "export": No such file or directory [errno 2]"
OS is Raspbian Buster (updated)
Coding with Geany
Thanks for any help in advance.
Regards Taz
[CODE title="PWM periphery" highlight="4"]
local PWM = require('periphery').PWM
-- Open PWM chip 0, channel 10
local pwm = PWM(0, 10)
-- Set frequency to 1 kHz
pwm.frequency = 1e3
-- Set duty cycle to 75%
pwm.duty_cycle = 0.75
-- Enable PWM output
pwm:enable()
pwm:close()[/CODE]
