LEDCFade not stoppable, workarount to a assign a new fade-target

[BerndN]

ARDUINO ESP-Board 2.0.18

I have a callback-routine which is called when the led switches ON or OFF or a new brightness (a slider in the Alexa-App is moved around. The

bool ledcFade(uint8_t pin, uint32_t start_duty, uint32_t target_duty, int max_fade_time_ms);

stucks if it is called again before the fade ends.

Code: Select all

callback(newbrightness)
{
	ledcFade(port_LED_l1, ledcRead(port_LED_l1), newbrightness, FADETIME_MS);       // fade 3 secs
}

the workaround is calling a ledcWrite() with the actual duty cycle always before new ledcFade()

Code: Select all

callback(newbrightness)
{
	ledcWrite(port_LED_l1, ledcRead(port_LED_l1));     // init, if a fade is running it helps not to get stuck
	ledcFade(port_LED_l1, ledcRead(port_LED_l1), newbrightness, FADETIME_MS);       // fade 3 secs
}
