dfrobot_vl53l0x's Issues

How can I use 2 of this sensor, How to change I2C address?

Hi,

I'm trying to use 2 sensors, how can I change the I2C address so I can use both of them at the same time?

Thanks.

Why a delay after Wire.read() ?

In the file "DFRobot_VL53L0X.cpp", there is a delay(1) after each Wire.read() in the function readData().
The Wire.read() gets a byte from a buffer (a buffer inside the Wire library). The I2C transaction on the bus was already ended before the Wire.requestFrom() returned.

It is similar to this:

int x[4];
int y[4];
y[0] = x[0];
delay(1); // wait until data is copied from one memory location to the other
y[1] = x[1];
delay(1); // wait until data is copied from one memory location to the other

I don't know the processor of the BLE4.1 and which Wire library is used, but the ESP Wire libraries are compatible with the Arduino Wire library and use a buffer. Even when no buffer is used, that delay has no meaning.

Is there maybe a bug in a Wire library that was solved with this bug ?
