@Sugarbearscode Thank you for your kind words. However, I do not post pre-built binaries.
You do not need C++ experience to build this code. You only need to install the pico-sdk according to the getting started guide and then follow the build instructions in this project's README.md file. If building any Raspberry Pi Pico C code is more than you want to learn how to do, perhaps you may find the Arduino version of this project easier to build. The Raspberry Pi support forums may also be helpful.
If you do decide to have a go at building the .UF2 file yourself and find it is not working, I am willing to help, but only if you describe what computer operating system you are using (Windows, Linux, MacOS), what steps you took to build the code, and attach output to show where things went wrong.

Ok. So I have got to the point of building the file but I get this error.
I think the instructions are wrong for building on the pico (I dont have a linux machine) but I get an error on "make"when I use these instructions on the Raspberry PI 4
this doesn't work on the Pico (foo is changed to PICO on the raspberry pi 4).
export PICO_SDK_PATH=$HOME/foo/pico-sdk/
cd $HOME/foo/midi2usbhost
mkdir build
cd build
cmake ..
make
I think it should be this which is the standard . The midi2usbhost directory is the same level as the pico-examples directory.
export PICO_SDK_PATH=$HOME/pico/pico-sdk/
cd $HOME/pico/midi2usbhost/C-Code/
mkdir build
cd build
cmake ..
make
If I use this then I get as far as make, which works ok until it gets to Building C Object CMakeFiles/midi2usbhost.dir/midi2usbhost.c.obj
This is the output from make.

Can you suggest what is wrong?

If I try to use CMAKE .." using the example in the README I get this error on the raspberry pi 4

@Sugarbearscode Thank you for posting this information. Clearly I need to update the instructions and I will do so shortly.
@DatanoiseTV I am not sure that the versions of TinyUSB that have the bsp/board.h file support Application USB Host drivers. I need to investigate.

@rppicomidi not sure what I did, but it seems to be fixed now.
I went back over the steps of updating the TInysub library and it did have a reboot overnight, maybe a fresh pair of eyes have fixed it but it all compiled without any issues today.
When I get time I will do everything from scratch again and see if I get the same issues.
Thanks

@Sugarbearscode Wow. Thank you. Nevertheless, I am going to reopen this until I fix the documentation. @DatanoiseTV USB Host Application drivers were introduced August 15, 2023 and the file bsp/board.h was renamed to bsp/board_api.h August 3, 2023, so while I thank you for your suggestion, I am going to omit it.
