“Simple FM Radio with a beautiful retro look linear scale.
This time I will present you how to make a simple FM Radio with a beautiful retro look linear scale. The idea for the project was taken from the Volos Projects channel, where is presented the code that was specially made for the LilyGO T-Embed device, which has a TFT screen with a resolution of 320 x 170 pixels.
I just adapted the code for the ILI9341 TFT Display which has a resolution of 320×240 pixels powered by an ESP32 dev kit module. The radio interface is the same, and in the remaining part of the screen I added a small clock that shows the time. Actually, as a beginner in programming, I did a little practice drawing figures and placing text on the Display. The way the scale moves is especially effective for me as a big fan of retro radios. For the FM radio part, the TEA5767 radio module is used, which is characterized by good features and a relatively low price. “
