Hi there, I'm trying the new version.

My CYD 2.8" ESP32-2432S028 works with WiFi, and the new serial version only on ttyUSB0.

But can't connect to the ttyS1 port that was of the previoud Nextion/TJC monitor.

The CYD has both an USB port and a port with a jst1.25 4 way with label 5v, RX, TX, GND.

I've to say that I've full control of my printer with a fresh Armbian based on Ubuntu Noble on a SKIPR mainboard. ttyS0 is the THR connected by UART. And I saw previous display was a ttyS1. There's also ttyS2 but I've tried both.

Cabling is correct and I've tried both directions of TX and RX.

Some other user reported that the cyd 2.8" contains a design defect that leaves RX disconnected #100 (comment)

To be able to use that port, I manually recompiled the library and swapped TX/RX in the initialization of the serial.
