Hi,
my main goal is to install a fan and control it's speed. I have a Noctua fan with PWM support. I've tested the functionality on a raspberry pi 3B+ with the GPIO.18 pin that generates PWM.
I have a bunch of questions about how to replicate this on a Nanopi M4. I'm not experienced in electronics, so please don't get mad if I say something stupid, I'm just trying to learn.
- Is there a GPIO pin on a NonoPI that generates a PWM signal? I saw that there is one on the 24-pin header, but I don't know how to use it.
- Can I set the PWM with Wiringpi? This is the main library that I use so script something with GPIO. According to http://wiki.friendlyarm.com/wiki/index. ... t_value.29 I should be able to set a pin mode to PWM_OUTPUT, but it gives me a warning: pinMode : Unknown Mode 3
- I would be very thankful for any other recommendations as my nanopi overheats very fast without a fan and it's a bit too noisy to have the fan running at 100% all the time
