Hi all.
I have an exhaust valve controller project I am currently doing. I have the controller which came with the valves but I want to make my own controller from an ATmega328p (Custom Arduino) with extra options like geofencing and time-based functions.
What I am trying to do is replicate the PWM signal from the valve controller and write it to an Arduino. I have never used a scope before and not sure if I understand the measurements. From what I think I can understand is, the signal is at 2.4khz and at a duty cycle of 50% but the OFF and ON signals look slightly different.
Is there anyone who could understand the signals and educate me on them, please?
Here is a link to the Hantek WAF Files, If you have a Hantek or a scope that can open WAF files: https://drive.google.com/drive/folders/12d0EpRkXBP3IsG-vZXz2ClF0c1DnEWgl?usp=sharing
I have put the controller on the scope and have come up with the following.
When the OFF button on the remote is pressed the valve gets closed and the controller outputs this wave:
and when the ON button is pressed the valve opens and the controller outputs this wave:
Mike.
