Read serial data from an external device using USB port
Posted: Mon Dec 18, 2023 2:16 am
I have a 3D printer that exposes serial via a USB-C port to send & receive data. Can I connect it to an ESP32 and read the printer's messages? The goal is to run a small program on ESP32 that communicates with the printer via serial / USB and publishes it via MTTQ or HTTP.
