A hamradio station remote control is usually done by an application installed on a dedicated machine, this application being often developed according to an operating system (Windows, Unix, …). This video shows a FT-857D remote control using an application developed on a web browser and therefore independent of the system. The web server is an ESP32 TTGO micro-controller board connected to the FT-857D.
The developments are based on those described in the article on FT-857D parameters display on an ESP32 board.
The video presents the developments functional aspects.
The video is in French but is subtitled in English.
The work was to port the FT-857D CAT library and the corresponding display application on the ESP32 T-Display. This software was originally developed on an Arduino Nano (see article) The goal was to have a platform of the same size as the Arduino Nano but with in addition to the serial link, an on-board WiFi and Bluetooth.
This application: – displays an image and then a timed sequence of screens of different colors (red, blue, green), – displays the power voltage on short-pressed GPIO 35 button, – puts the ESP32 to sleep on the GPIO 35 button long press, – launches a WiFi scan on short press of the GPIO 0 button and displays the result.
