DIY Si4732 LW,MW,SW,SSB Radio with 2.8 inch touch TFT display

Today, after several months of waiting, I received a Si4732 chip. That was the reason for the new video. The previous video( • DIY Si47xx All Band DS... ) describes the same Radio receiver but made with Si4730 Radio module, which due to the limited capabilities of the chip could not receive Shortwave and SSB signals. Now with this chip, the radio is complete.
In short, the radio contains a several components :
- ESP32 microcontroller board
- SI4732 radio chip
- 2.8 inch TFT colour display with Touch screeen
- Small D-Class power amplifier board
- Speaker
- Lithium Battrey 3.7 Volts
- Lithium battery charger
- Upconverter board 3.7 to 5V
- Rotary encoder
- and Potentiometer
Si4732 chip can be purchased on Aliexpress at a price of about US $ 10 for one piece, or US $ 21 for 5 pieces. Now the Radio has new firmware from Gert Baak with more visual and functional improvements.
Immediately after switching on we can see a new graphical interface with rounded 3D buttons.
First of all, a 100 and 10 Hz digit has been added. The radio is now tunable in SSB in steps of 1 Khz, 100 Hz and 10 Hz. The desired digit can be selected on the TFT screen by pressing it. The selected digit is underlined. In line 86 and 87 in the program, you can select the crystal or the clock generator. In our case, due to simpler construction, the clock generator is selected, which is part of the Si4732 IC. On the first screen, the volume can be adjusted by pressing the encoder key first. The volume can now be adjusted by turning the rotary encoder. When the button is pressed again, the regulation is switched off. This can still be done with the VOL button. It is now also possible to control the screen lighting. This can be done on the second screen with the DISPL key. After pressing, the light intensity can be adjusted using the rotary encoder. The volume scale now indicates the setting.
Also on the display, we have only necessary information like Frequency, RSSI value, Signal to Noise ratio, etc. Unfortunately, the video is of poor quality due to the poor camera features. In reality, the content of the screen is crystal clear. Finally, the radio is mounted in a suitable box made of PVC and coated with self-adhesive wallpaper.

Thanks so much for putting so much detail into this video. So often videos assume the viewer has more than beginner's knowledge and it is easy to get lost! I was able to follow this as a newbie and may well try to build one. Please keep these projects coming.

[@MirkoPavleskiMK]

Thanks

[@Evilslayer73]

I managed to upload the sketch i connected the screen all is working so far :) now i need to connect the rest of the schematic loll :) im very happy! i have another question do i need 2 ceramic capacitor like in the schematic or just one ? because in the video i see just one soldered to the crystal?!?

[@riguelnove2564]

I get this error " ledcSetup' was not declared in this scope " can anyone help me?

[@mayxnerde2952]

Thanks for the Video , and a big thanks for Share the schematic diagram and Software links , thats very very helpful for rebuilding / replica

[@mayxnerde2952]

I am again ... ;-)
I have a question:
does the display have to be programmed separately via sd card (like a nextion display) ?
or the display is programmed with the code from the esp32 ?

The display is programmed with the code from the esp32

Thank you.

[@MirkoPavleskiMK]

Do you mean #include

[@MirkoPavleskiMK]

The library "TFT_eSPI" is missing. You need install it

Was this RX'r recently featured in Elektor Magazine?

[@FixTronics]

Beautiful

[@mustang2440]

Wow, amazing build and features! I imagine the performance is also dependent on the antenna used, can you comment on the type of antenna used?

[@renatoalvesdesouza3219]

What a beautiful project, congratulations, One question can use a 2.4 inch TFT color screen with touch screen
IL9341?

[@MirkoPavleskiMK]

Thanks, , yes you can use 2.4 inch TFT with ili9341 without modification in code

[@maksland8099]

ESP32 standard on 32Mbit ?

[@mayxnerde2952]

... super DIY Video , thanks a lot
can you give us a link to buy a right display please , many thanks and greetz from germany
