KD8CEC's uBITX Display Routine for LCD1602 Parrel
1.This is the display code for the default LCD mounted in uBITX.
2.Display related functions of uBITX. Some functions moved from uBITX_Ui.
3.uBITX Idle time Processing
Functions that run at times that do not affect TX, CW, and CAT
It is called in 1/10 time unit.
