4-Software Setup – Pi Pico – 1 Library

Software Setup

Once the wiring is done and everything is hooked up to your game system and computer, now for the easy part.

1. Make sure the the USB cable between your Arduino and PC is connected and if you are not going to program your own board you can now skip to Step 10.
2. Open the Arduino software that you installed above and go to the Tools menu and set:

   Option	Value
   Board	Raspberry Pi Pico
   Flash Size	2MB (no FS)
   Optimize	Optimize Even More (-O3)
   CPU Speed	250 MHz (Overclock)
   RTTI	Disabled
   Stack Protection	Disabled
   C++ Exceptions	Disabled
   Debug Port	Disabled
   Debug Level	None
   USB Stack	Pico SDK
   IP/Bluetooth Stack	IPv4 Only
   Upload Method	Default (UF2)

3. You should now see something along the lines of “Raspberry Pi Pico…on COMX” at the bottom right corner if everything is working. If not, you may need to restart and/or replug the USB connector.
   
5. Open common.h in the RetroSpy installation directory (by default this is C:\Program Files (x86)\RetroSpy\firmware) with any available text editor and uncomment the line to enable the use of the library in the RetroSpy firmware.
6. In the Arduino software select File->Open from the menubar and open the firmware.ino file from the firmware folder of the installed RetroSpy release (by default this is C:\Program Files (x86)\RetroSpy\firmware).
7. Now uncomment the option for MODE_SNES. Note that MODE_SNES is uncommented in this image.
   
8. Hit the upload button (right pointing arrow) located just under the ‘Edit’ menu, this will upload and run the software on the Teensy. You will very likely need to push the button on the board in order to program it. It should look like the following image. Once successfully uploaded, you won’t have to upload software again to the Teensy again unless you want to change controller modes.
   
9. Power on your console.
10. Run RetroSpy.exe.
11. The selection here should be pretty straightforward, select the ‘COMX’ port that the Teensy is on, select the controller you are using, select a skin, and hit ‘Go’. If everything is hooked up correctly you should see your controller and inputs displaying.
