The difference with this one is the use of a bigger screen, 3 push buttons and the use of a rotary switch. Therefore, a whole new user interface had to be developed.
Why 3 buttons, because with the bigger LCD, you need one more output (for en2), and since I also wanted to control the LEDs in the pushbuttons, another output was needed.
To control a 4x40 LCD, you need a special library. I had tried different version, but there was only one that was usable with the 4x40 LCD. After an update of my libraries, my program did not work anymore. I had to reïnstall the older version. I did not investigate why, but you need a certain version of an LCD library (included in this project).
This is the backplane of the LCD. It is a PCB with a supply on board for the backlight of the LCD (top) and some components for controlling the contrast (bottom).
With the bigger screen, it is easier to display a lot of information. In this version data from the radio station is displayed. These are RDS-like messages. These are not slight shows or other graphical data (possible with DAB+ transmission). For this kind of data, one needs a DAB+ tuner with dataservice option.
Here is the result:
The function of the tree buttons are:
LEFT: This is just for on or off. It controls the RESET pin of the tuner and the leds of the buttons. In this version, I don't control the backlight.
MID: This is the mode button. You can set the software in different mode to control, for example, the volume or station frequencies.
RIGHT: When set in a certain mode, you must activate this mode. So you can turn on the rotary switch but when mode is not active, nothing is happening. Or, in FM, you can search for next station, you must activate the search with this select button.
ROTARY ENCODER: With this encoder, you can change different setting, like volume, equalizer. But you also tune in (like a analog radio) on a FM station or select another DAB+ station.

// With this software you can use the T3B DAB+ tuner on a UNO
// it is written in a way that everyone could understand the software
//
// hardware : UNO; 4X40 lcd; 3 key's; rotary encoder
//
//The DAB search should be done each time when you use the
// tuner in a new environment.
// The search takes some time.
//
// RESET function : via digitalout 2 (modified interfacd PCB
//
// IMPORTANT NOTICE : the baudrate should be at 57601 (as described in some forums).
