How to Toggle RGB Modes with Rotary Encoder?

[pabile]

hello gh, i have my custom keyboard with 40 WS2812B leds and 2 ec11 rotary encoders. i am running QMK and the keyboard is working great. i can toggle rgb modes using key combinations but what i wanted is to toggle rgb modes and/or colors using the 2 rotary encoders installed. so, my question is, how do i do this?

what i want for my keymap.c but does not work:

Code: [Select]

void encoder_update_user(uint8_t index, bool clockwise) {
    if (index == 0) { /* First encoder */
        if (clockwise) {
            tap_code(RGB_MOD);
        } else {
            tap_code(RGB_RMOD);
        }
    } else if (index == 1) { /* Second encoder */
        if (clockwise) {
            tap_code(RGB_HUI);
        } else {
            tap_code(RGB_HUD);
        }
    }
} 

when i use the above keymap, i am getting this error:

Code: [Select]

i arrived to this after a help from a local guru:

Code: [Select]

void encoder_update_user(uint8_t index, bool clockwise) {
    if (index == 0) { /* First encoder */
        if (clockwise) {
            rgblight_step();
        } else {
           rgblight_step_reverse();
        }
    } ...

i am yet to finish reading this document sent to me but i guess possibilities are truly limitless with QMK

if you find yourself stuck with trying to implement something in qmk again, the qmk docs is your friend

thanks! i am indeed going back and fort to the docs trying to find the right settings for the promicro and rgb. my keyboard is acting up and could not seem to properly power my leds
