While I was making the video I wondered about covering frequency. It is not possible to set the frequency per channel. But it it is still worth covering. I am working on the script for the Nextion built in PWM and I am going to include frequecy in that video. I will look to do a follow up video on the PCA9685 with that info. Show both internal and External clocking.
good tutorial, can you help me for sending and receiving from tiva c series tm4c to nextion. i will be very thankful to you. stuck in between. not getting data
I describe how I calculate the channel at about the 11:30 point in the video, then at 12:54 on line 53, I send the channel. You don't do this in the Nextion. You do this in the Arduino, This video is using the Nextion to control an Arduino and then using the Arduino to control a PCA9685. The Nextion does have built-in PWM but it does not have I2C so you have to use something to convert the signal from the Nextion to the PCA9685. I used an Arduino but I am sure you could use a different device if you wanted. I hope this helps
great tutorial as always :) Do you know if it's possible to set a different PWM frequency for each channel?

Thank you.
You're welcome!

Are you familiar with running the Nextion IDE in Debug mode?
I don't get where you entered chann and value, I don't have any where to enter it in my version of the Nextion IDE, can you give me a hint? Thanks.
I don't remember that video very well. I will do my best to review it tomorrow and post a follow-up with your answer.
