MicroPython Bootloader Setup

1. Upload the firmware :

   Press and hold the BOOTSEL button on the Raspberry Pi Pico board while connecting to the computer via a micro USB cable. After the Raspberry Pi Pico is recognized by the computer (connected), then immediately release the BOOTSEL button. When successfully connected, a new drive called RPI-RP2 will open. Drag -> Drop or Copy -> Paste the MicroPython UF2 firmware file into the RPI-RP2 drive.

   
   

2. After the process is successful, the RPI-RP2 drive will automatically close.
   
   

3. In general, the firmware upload only needs to be done once when you first use the Raspberry Pi Pico board.

Thonny IDE Setup

1. Open Thonny IDE first.
   
   

2. Click Tools -> then select Options... -> then select :
   
   

   • Interpreter Menu, then change the part :

   Interpreter -> MicroPython (Raspberry Pi Pico) Port -> Board CDC @ COM... Restart interpreter before running a script -> uncheck

   • Editor Menu, then check all the options except: Indent with tab characters.
   
   

3. If the file view does not exist in Thonny IDE, then please click the View -> section and select Files to display it.
   
   

4. Then look for a file called main.py in directory: LED-Musik-Reaktif-Berbasis-Raspberry-Pi-Pico/Src.
   
   

5. Right click on the file -> select Upload to /.
   
   

6. Open the file main.py which is in the Raspberry Pi Pico storage -> then click Run current script (F5).
   
   

7. Program code executed successfully -> sign: %run -c $EDITOR_CONTENT.
   
   

8. If there is still a problem when uploading the program, then try to check the interpreter / port / others section.
