SI4732 ontvanger
Geplaatst: 25 apr 2021, 20:01
AliExpress adverteert met SI4732 kortegolf ontvangers. Kost zo'n 25 tot 50 Euro afhankelijk of je met of zonder kastje aanschaft. De radio is gebaseerd op een SI473x chip en wordt aangestuurd met een Arduino. De programmatuur is gebaseerd op een bibliotheek ontwikkeld door PU2CLR. Er zijn all verschillende youtube video's online. Ook is er een FaceBook groep actief. Ik heb zelf een versie met kastje aangeschaft. De kwaliteit laat zeker te wensen over, maar het werkt (nog). Omdat ik geen lid van FaceBook wil worden heb ik zelf maar uitgezocht hoe dat apparaat te programmeren is. Nu kan ik zelf het programma (de sketch) aanpassen en verder experimenteren :
ATS 20 radio programming with Raspberry Pi 4 running Ubuntu Mate 20.10
Too cumbersome to find serial drivers for Windows
Start the Pi
Make the user a member of the group dialout to be able to use the serial port for uploading
Administration
Users and Groups
Manage Groups
Select dialout
Mark the user to become a group member
OK
Close Manage Groups
Connect the radio to an USB 2.0 port
Reboot the Pi to activate the user’s dialout membership
Switch on the radio to activate the radio’s serial port
Get the SI4735 repository with specific programs for this radio and other projects
Use a terminal command to clone the repository
>git clone https://github.com/pu2clr/SI4735
Install Arduino IDE manage the built in Arduino
Download Arduino IDE voor Linux ARM 64 bits
https://downloads.arduino.cc/arduino-1. ... h64.tar.xz
Use file manager to extract the files from the container to your home directory
Use file manager to go to the new directory
Use file manager and right click to open install.sh
Set up the Arduino IDE to program the radio
Use file manager to go to: ~/SI4375/examples/SI47XX)KITS/AlieExpress/SI473X_ALL_IN_ONE_OLED_RDS_CHINESE
Use file manager and right click to open with Arduiono IDE
SI473X_ALL_IN_ONE_OLED_RDS_CHINESE.INO
The Arduino IDE opens and the do the following
Tools
Manage Libraries: Install SI4735 library, install Tiny4kOLED library
Set Board to “Arduino Nano” (that’s what was printed on my Arduino)
Set Processor to “ATmega328P (Old Bootloader)”
ATmega328 wat was printed on the chip of the Arduino
Old Bootloader was recommended after an error messages)
Set Port to “/dev/ttyUSB0”
Finally upload the sketch with the IDE
Sketch
Upload
The radio will reboot.
Now you can edit the sketch and repeat the upload to further experiment.
