RGB Underglow not working

Sanic commented 5 years ago

Hi!

First things first: Thank you very much for this nice project. I built a wired redox over the couple last weeks and i'm close to finishing this project. The keyboard functionality itself does work on both halves, but i have problems getting the RGB underflow (6 LEDs per half) working. I've flashed both halves with the same firmware using the following config.h:

/* Use I2C or Serial, not both */
#define USE_SERIAL
// #define USE_I2C

/* Select hand configuration */
#define MASTER_LEFT
//#define MASTER_RIGHT
// #define EE_HANDS

#undef RGBLED_NUM
#define RGBLIGHT_ANIMATIONS
#define RGBLED_NUM 12
#define RGBLIGHT_HUE_STEP 8
#define RGBLIGHT_SAT_STEP 8
#define RGBLIGHT_VAL_STEP 8

I didn't write the EEPROM content. This isn't needed when i'm not using EE_HANDS, right?

Right after flashing, the RGB underflow didn't work. Should it light up per default? After checking the current keymap in the qmk repo, i saw that the light can be toggled on the ADJUST layer with RGB_TOG. I've tried that but it didn't help. Other keys (such as F3, F4) are sent fine, so i think that i'm on the right layer. The rules.mk is still on the default values:

BOOTMAGIC_ENABLE = no      # Virtual DIP switch configuration(+1000)
MOUSEKEY_ENABLE = yes       # Mouse keys(+4700)
EXTRAKEY_ENABLE = yes       # Audio control and System control(+450)
CONSOLE_ENABLE = no         # Console for debug(+400)
COMMAND_ENABLE = yes        # Commands for debug and configuration
# Do not enable SLEEP_LED_ENABLE. it uses the same timer as BACKLIGHT_ENABLE
SLEEP_LED_ENABLE = no       # Breathing sleep LED during USB suspend
# if this doesn't work, see here: https://github.com/tmk/tmk_keyboard/wiki/FAQ#nkro-doesnt-work
NKRO_ENABLE = no            # USB Nkey Rollover
BACKLIGHT_ENABLE = no       # Enable keyboard backlight functionality on B7 by default
MIDI_ENABLE = no            # MIDI support (+2400 to 4200, depending on config)
UNICODE_ENABLE = no         # Unicode
BLUETOOTH_ENABLE = no       # Enable Bluetooth with the Adafruit EZ-Key HID
AUDIO_ENABLE = no           # Audio output on port C6
FAUXCLICKY_ENABLE = no      # Use buzzer to emulate clicky switches
RGBLIGHT_ENABLE = yes       # Enable WS2812 RGB underlight. 

SPLIT_KEYBOARD = yes

DEFAULT_FOLDER = redox/rev1

The rules.mk in the default keymap is also still on the default and enables RGBLIGHT_ENABLE

Hardware-wise, i checked that the RGB strips have +5 Power and i also checked that TX0 on the left hand master is connected to the DIN of the RGB strip in the left hand.

Do you have any suggestions how i can debug this further?

Hi, you seem to have everything set correctly.

I didn't write the EEPROM content. This isn't needed when i'm not using EE_HANDS, right?

You're correct, it isn't needed.

I have two suggestions:

As of the latest pull request the RGB backlighing is supported by default. Compiling and unloading the default keymap without any modifications should lights the LEDs up.
Here you can find a precompiled hex with rgb support to double check if it is a software problem.

I neither of the above work it should be a hardware problem.

Hi,

thank you for the clarification. This helped me to track the error down. I've used an RGB colorstrip that worked fine when using the supplied connector, but for putting it into the keyboard i desoldered the cable. I guess the pcb didn't like that. Cut off the first LED and now it works fine! Thanks!

Great! Glad I was able to help :smile:
