Get I2C bytes ready.
This method checks the number of bytes that are ready to be read on the specified port. If the last operation on this port was a successful I2CWrite call that requested response data from the device then the return value will be the number of bytes in the internal read buffer.
|port||The port to which the I2C device is attached. See the Input port constants group. You may use a constant or a variable. Constants should be used where possible to avoid blocking access to I2C devices on other ports by code running on other threads. |
- The number of bytes available to be read from the internal I2C buffer. The maximum number of bytes that can be read is 16.
