This project controls the RTC6705 that is used in many 5.8GHz FPV Transmitters. Connection diagrams are described in the .ino project.
You need an I2C 2×16 LCD, a rotary encoder, and an Arduino nano.
Swap between Freq1 and Freq2 by pressing the rotary.
Frequency changes are not instant as the RTC6705 has the most ugly behavior ever. So updates are committed after 1.5 seconds. You’ll see when you run the code 🙂
New posts will follow showing connections to actual FPV transmitters. Keep watching this space!
