+/**
+ * Changes :
+ * (1) ra8876lite.begin() -> ra8876lite.begin(&CEA_1280x720p_60Hz) for less heat from HDMI encoder.
+ * Instead of using onboard boot ROM with ra8876lite.begin(), an argument &CEA_1280x720p_60Hz is now used for initialization.
+ * Resolution is the same at 1280*720 60Hz output from RA8876 for both methods. With boot ROM, it is possible to fetch EDID information
+ * from a TV/monitor. With explicit argument &CEA_1280x720p_60Hz no EDID is available.
+ * This change is to avoid overheat from CH7035 HDMI encoder leading to overloading of 5V supply from USB cable. 
+ * (2) New function HDMI_Tx.init(VIDEO_in_1280x720_out_HDMI_1080p_60Hz) after HDMI_Tx.begin() to initialize CH7035B for
+ * 1280*720 video input -> 1080p 60Hz HDMI output. 
+ * Date: 29th Jan 2019
