ESP32 Programming: UART bridge to RS485 in ESP-IDF framework
Budget: $15 – $25 AUD
Hi All,
We have a programming job that requires an ESP32 to be programmed as a serial to RS485 bridge.
We want this to be programmed within the ESP-IDF framework to take advantage of the serial buffer interrupts. Code to be programmed in VSCode with the PlatformIO extension.
We require a base code that is a simple uart bridge between serial0 and serial2 RS485.
The rs485 needs to use interrupts for the tx enable pin and not block the code from running.
Details:
Code needs to run on the ES32-WROOM-32
Serial0 @ 115200bps
GPIO1 = TX
GPIO3 = RX
Serial2 RS485 @ 9600bps
GPIO16 = TX
GPIO17 = RX
GPIO18 = RX Enable
GPIO19 = TX Enable
The successful applicant needs to have full understanding of RS485 hardware, ESP-IDF and VScode/PlatformIO.
The code must be interrupt driven for the RS485.
Please see the attached schematic and image of the product.
