I can't change the speed of the fans I am using, which is a Evercool.
The wiring is right, but maybe I've burned something out.
Used a number of EMC2101 but there's no difference. I've used the standard example and the LUT versions, doesn't make a difference, all one high speed.
What makes me very concerned is that when I started I believe the basic code did change the speed. I hope I didn't burn something out. I have different fans to try but I think I've bricked 4 EMC2101

How do you connect and what do you connect the EMC to? What code are you using and can you post pictures? Thanks.

The main processor is the ESP32S3 with screen. There is a multiplexer attached because there is the address conflict with the 2 EMC2101's.
When the power is on for the EMC2101's one of the fans is low and the other is high but they both are spinning at a high speed.
I've also attached the code, besides the pictures.
Thank you for your assistance.

Hi:
Still stuck, can't get the sample CircuitPython code to change the speed of my fans.
I have tested the fans with a knob based module and I can change the speed, so its not the PWM fans.
Must be doing something wrong but can't figure out what it is.

The example code would need to be adapted for use with the I2C muxer.
Try connecting just a single EMC2101 directly the Feather ESP32S3 (don't use the muxer) and then run the example code:
