Cannot set brightness dynamically? #7

Closed ThePureCC closed 8 months ago

ThePureCC commented 1 year ago

I have a bunch of codes that looks like this to change the brightness:

} else if (strcmp(message.data().c_str(), "brightness30") == 0) { strip.setBrightness(30); delay(10); strip.show(); } else if (strcmp(message.data().c_str(), "brightness50") == 0) { strip.setBrightness(50); delay(10); strip.show();

however it doesn't seem to change the brightness at all.

Is the brightness setting only able to be set at start? Would it be possible to change brightness dynamically?

The method of use is correct. Maybe there is no entry if.

strip.setBrightness(bright); //This function did not trigger any action. strip.setAllLedsColorData(255, 255, 255); //This function is needed to trigger the setup. strip.show();

/***** Function code ****/ void Freenove_ESP32_WS2812::setBrightness(u8 brightness) { br = constrain(brightness, 0, 255); }

esp_err_t Freenove_ESP32_WS2812::setLedColorData(int index, u8 r, u8 g, u8 b) { u8 p[3]; p[rOffset] = r br / 255; p[gOffset] = g br / 255; p[bOffset] = b * br / 255; return set_pixel(index, p[0], p[1], p[2]); }
