Hi everyone,
I'm building a custom keyboard, and for the programming part I just followed matt3o's guide:
http://deskthority.net/workshop-f7/how-to-build-your-very-own-keyboard-firmware-t7177.html

I have no knowledge whatsoever in programming, so the guide helped me a lot!
My keyboard is nearly ...

You may have the LED wired the other way, i.e. pin --- LED --- resistor --- 5V, rather than pin --- LED --- resistor --- GND (as assumed for the above code). If that's the case, you need to change the first branch of the if statement to

DDRD |= (1<<6);
PORTD &= ~(1<<6);

Other than this, I can't ...

Modified from gh60 to use pin D6:

void led_set(uint8_t usb_led)
{
if (usb_led & (1<<USB_LED_CAPS_LOCK)) {
// output high
DDRD |= (1<<6);
PORTD |= (1<<6);
} else {
// Hi-Z
DDRD &= ~(1<<6);
PORTD &= ~(1<<6);
}
}


Tried using this function but it didn't work when I turned on the caps lock ...

Caps lock led is normally set in led.c, in the led_set function, just like in other keyboards (see e.g. gh60 example).

The point is that the "toggled" led indicators (caps, num, scroll locks) are dealt with in the led_set function, while the "layer" leds in the led_layer_set function.

I tried ...

In C, each function has to have a unique name - your code defines 2 functions with the same name. So, you'll need to combine the two LEDs into one function:

void led_layer_set(uint32_t state) {
DDRC |= (1<<7);
DDRD |= (1<<5);

/* Led for Layer 1 */
if ((1<<1 & state) != 0) {
PORTC |= (1<<7 ...

Here's another way (there's a pull request about this on github: https://github.com/tmk/tmk_keyboard/pull/198 )
Namely: edit tmk_core/common/action_layer.c like this:
- line 6, add #include "led.h"
- line 66 (between 'layer_state = state;' and 'layer_debug(); dprintln();') add led_layer_set ...

After a few days of programming and re-soldering what apparently was a non-functioning diode, the keyboard works perfectly!
Thanks again for the help.
Now I need to figure out how to program toggle LEDs on my two toggle function keys and on my CAPS lock key.

Halvar wrote: F0 in your first layer is an undefined keycode. Maybe you mean FN0?

You can look up the available codes in the file /common/keycode.h

Yes!!!
That was my mistake - I wrote my function keys as "Fx" instead of "FNx"!

Thank you, Halvar!

Is that with the unchenged source?

The error message

keymap_poker.c:8: error: 'KC_F0' undeclared here (not in a function)

looks like a pretty normal error in your keymap_poker.c file. If this is your code and you don't find the error, post your poker.c file.

Hey Halvar, thanks for your quick ...

Hi Tomer, welcome to DT!

Yes, that's a known problem. Solution is here:

Hi Halvar, thank you for your welcome!
I tried the fix, and this is what I got:

Hey, I keep getting these errors on the cmd when I compile, even when I try to compile the gh60 right from the source.
