Control a RigExpert AA-30 ZERO from a Nextion 2.8" HMI LCD using an Arduino
Upload this to your Arduino Uno. All it does it move data from the AA-30 to serial and back. Same thing as shown in the "Getting Started" on RigExert's site.
A Python script that listens for input from the Nextion on the serial port and causes the AA-30 ZERO to analyze the specified Amateur Radio band frequency's SWR rating given the connected antenna and measure its reactance.
Make the LCD work
Output commands from the LCD over serial
Interpret those commands in the Python scipt, send the coresponding command to the AA-30
Inpterpret and plot the return data from the AA-30 on a Waveform on the LCD
Possibly integrate https://github.com/vsergeev/rigexpert-tool rather than "re-invent the wheel"
