Hi. I'm using the previous version of the GD02 G15 driver and planning on using the hardware Serial 1 (Tx1 and Rx1) of the Arduino Mega which is pin 18 & 19, if I want to use the hardware serial instead of software serial since Arduino Mega consists of 4 pairs of hardware serial. What are the necessary changes in the libraries that will allow me to use hardware serial pin 18 & 19 of the Arduino MEGA.
Thank you.
