Ergonomic, split and other weird keyboards

Rules

Keep it ergo

Posts must be of/about keyboards that have a clear delineation between the left and right halves of the keyboard, column stagger, or both. This includes one-handed (one half doesn't exist, what clearer delineation is that!?)

i.e. no regular non-split¹ row-stagger and no non-split¹ ortholinear²

¹ split meaning a separation of the halves, whether fixed in place or entirely separate, both are fine.
² ortholinear meaning keys layed out in a grid

Having trouble with QMK firmware (drive.google.com)

I'm having trouble figuring out what's wrong with my files for compiling. the initial errors are pointing to the .h and corresponding part in the keymap.c files but it seems fine to me? i haven't even managed to get to figuring out the joystick part which is where i thought i would start having a bunch of trouble

Unsure the best way to show files but I don't think copy pasting them into the body of this post would be best so I've uploaded here: https://drive.google.com/drive/folders/1WKobV73ZdovPCUUcp0jLBLaX8L6IFEmp?usp=drive_link

The txt file shows the error text I get when trying to compile

Thank you

For the joystick part, do you have JOYSTICK_ENABLE = yes in your rules.mk?

[–] denton@lemm.ee 1 points 1 year ago (1 children)

Yep. QK_BOOT error was resolved after I updated, now it's just left with the joystick error. I've also uploaded rules.mk to the drive link

[–] obosob@feddit.uk 1 points 1 year ago (1 children)

your compilation errors now just seem to be because of mismatched braces. you have an extra closing brace in keymap.c before the xPos = analogReadPin(B4); as well as after the intended close of the matrix_scan_user method.

I've tried to rewrite the joystick code and now am getting different errors:

Also, I'm not sure if I need "#include "config_common.h" in my config.h file? I see it in some other config.h files. When I have that in my config.h file, it gives a fatal error: No such file or directory

[–] obosob@feddit.uk 1 points 1 year ago (1 children)

i don't think you need to include config_common.h, that's just a convention for when there are multiple revisions of a keyboard but most of the stuff is common.

as for the other code, try removing things until you get it to compile and start adding it back. it looks like the problem could be happening inside some macro expansion or something. i think it would help to format your code a bit to make it easier to follow, there's not really a need for the switch statement with only one case, etc. use consistent indentation, and such.

[–] obosob@feddit.uk 1 points 1 year ago (1 children)

so i had a crack at fixing it and got it to compile, obviously unable to test it functionally. I've pushed the code here.

I noticed you're not actually using the joystick features since you're reading the analog pins manually (btw, you should read them once per scan instead of in every if statement). so i just removed all the joystick code and the JOYSTICK_ENABLE = yes. i'm not sure what exactly you're trying to do but what I've got builds and doesn't remove any of the functional code, so see how you go from there. I don't know much about using the joystick feature in QMK so I can't really advise on how to use it instead of what you're doing, but as it stands you seem to not be utilising it anyway.

Good luck. if you're stuck, maybe try going to the QMK discord and explaining what you are trying to achieve and see what people say there. Be careful not to assume the implementation and ask the wrong question, describe what you want to achieve at a high level and see what they advise to implement it (see the XY problem)

I've actually got all the code to work now except the joystick part, which is the biggest (new) part for me for this keeb. I've been on the QMK discord (that's how I knew to update QMK to resolve QK_BOOT haha, although I'm not entirely sure the combo works...) What do you mean read the joystick input pins once per scan instead of in every if statement?

edit: yeah config_common is deprecated according to the QMK discord. very unfortunately I actually have no idea what I'm doing with QMK/C++ code (esp the joystick part) in general and have just been kinda sticking things I've found on the internet in in hopes of something working out but no luck so far
