RS485 Command & Status Program with XBee
Budget: €18 – €36 EUR
I'm looking for a simple program that enables a sender to dispatch control commands over RS485 to receivers via XBee radio links. The sender will be an ESP32S3 equipped with a 7" LVGL display, while the receivers will be standard ESP32s.
Key Features:
- The sender should be able to send control commands.
- The receivers should report their operational status back to the sender.
- Communication between the display and the ESP32S3 should be via UART.
Ideal Skills:
- Proficiency in programming with ESP32S3 and ESP32.
- Experience with RS485 and XBee radio links.
- Knowledge of UART communication protocol.
- Familiarity with LVGL display programming.
