rotaryEncoder.setEncoderValue() offset by one when value is negative about ai-esp32-rotary-encoder

[kr4fty]

setEncoderValue calls the reset() function, inside AiEsp32RotaryEncoder.cpp

void AiEsp32RotaryEncoder::setEncoderValue(long newValue)
{
	reset(newValue);
}

and inside the reset() function there is a "correction" parameter that sets the offset to 1 to our set value (in this case it is 1, but it depends on the set number of steps).

void AiEsp32RotaryEncoder::reset(long newValue_)
{
	newValue_ = newValue_ * this->encoderSteps;
	this->encoder0Pos = newValue_ + this->correctionOffset;
	this->lastReadEncoder0Pos = this->encoder0Pos;
	if (this->encoder0Pos > this->_maxEncoderValue)
		this->encoder0Pos = this->_circleValues ? this->_minEncoderValue : this->_maxEncoderValue;
	if (this->encoder0Pos < this->_minEncoderValue)
		this->encoder0Pos = this->_circleValues ? this->_maxEncoderValue : this->_minEncoderValue;

	this->lastReadEncoder0Pos = this->readEncoder();
}

If you eliminate that value correction, it would be showing you the real value

- this->encoder0Pos = newValue_ + this->correctionOffset;
+ this->encoder0Pos = newValue_; //+ this->correctionOffset;

correctionOffset is defined within AiEsp32RotaryEncoder.h with value 2.
I don't know very well the reason for this correction, the author will know how to tell us better.

int correctionOffset = 2;
