Note:

This is an ongoing project and errors will occur just to spite you. Currently, a few exist that basically mean nothing and are nearly unreplicatable. For VSCODE, The current language mode is incompatible is a favorite, and it effects a grand total of... nothing. Just disable it.

Setup for windows

After 50-60 hours and over a dozen individual attempts to get thing working on windows this is the only video that works

Here is the summary:

1. Download:

   • The GCC 10.3.1 ARM EABI compiler
   • Visual Studio tools
   • Python 3.9+
   • CMake
   • Git

2. Git Download the pico-sdk

3. Go to your computer paths and create a path named PICO_SDK_PATH to where the pico-sdk was downloaded. E.G., mine is E:/PiPico/pico-sdk

4. Search for Developer command prompt for VS2019 in the search bar, open it as administrator, and then type in code to open VSCode

5. Once in VSCode, install the CMake Tools and C/C++ plugins, go to the CMake Tools settings and set the CMake Generator to NMake Makefiles

6. Verify that CMake: Configure Environment is already set to PICO_SDK_PATH which should be the path to your pico-sdk folder

7. Close out of VSCode, and reopen it by typing code back into the terminal

8. Once VSCode opens back up, setup your project in the src/config.h file, set your compiler in the bottom left of VSCode to GCC 10.3.1 arm-none-eabi if not already set, and then click on Build right next to it.

9. Once built, take your Pi Pico, hold down the BOOTSEL button while plugging it into your computer and you should see it pop up as a storage device. Now go into the /build folder and simply drag over the j_cassette.uf2 file into the Pico's "drive" and it should start working

10. Screw around with it and have fun

NOTE!!! To compile this ever again you need to open Developer command prompt for VS2019 as an administrator and type code for this to work
