There's a touch screen on there too, and an SD slot.
All useless so far and the arduino nano is way too slow to do a real game, it's like programming an old 8-bit again, it takes a couple of seconds to draw a full 230x240 screen.

The game is from here - https://vilaca.eu/handheld-arduino-color-console/

With a few teaks as it didn't work with my screen, nor was it expecting a nunchuck.

I don't suppose someone can explain to me what the hell c++ expect me to do here...





It very much IS declared!!!

The "..in this scope" bit suggests that joystick isn't accessing the variables of the main file.
Did c++ do all that "Public/Private" stuff? I honestly can't remember which language is which anymore!!

Try setting the "Wii" stuff to Public, and see if that fixes it.

Current avenue...

joystick.cpp


joystick.cpp is included in a couple of other files, however surely that "WiiClassicControl Wii;" is doupble protected with the #ifndef's so surely can NEVER be defined more than once, but I still get...


One of the reasons I HATE the 'very portable' C based languages.

As a general rule, if you're including files in C / C++, you should only include header (.h, .hpp) files. When you compile your program, the compiler will compile every .c / .cpp file separately, then link them all together to create the final executable. So if one your files includes another .cpp file, you have defined the contents of that .cpp file twice - once in the original version, and once in the file you included it into.

|edit| To clarify slightly, the cause of your 'not in scope' error is that Wii is in scope in the code snippet you have posted, so that compiles just fine. However, when the compiler then compiles joystick.cpp, Wii hasn't been defined in that file! Hence the error. |edit|

i static'd the variable, fixed it right up.
just needs some sort of plastic boxy tning now.

I mean, that will technically make it work. Though I'd still be inclined to caution that including those CPP files will come back to bite you again later!

(renaming them to .hpp would have solved it without the static)

Right, currently got working -

tft screen
touch screen
wii classic controller

can I hell get the sd card to work! I managed to find a forum post some place where a couple of people were attempting to get screen+touch+sd working on this device, but their code links are dead, so I check the guys git hub where he posted them, they were deleted for being 'old' ... !!

Why would you do that?!!

Just going to drop this here before I loose it...



Note - I can get the sd card to work if the tft screen is configured wrong, that is, not working. Might have to look into interrupts or something to switch off the tft when reading the card or something.

That was my thinking - there's perhaps not enough power - CPU and electricity, to run the screen AND the SD card reader a the same time.
