Release notes for RA1792 PIC display interface. V6rc1 = First stable release, works fine with Hitachi HD44780 V6rc2 = Corrected timing issues, all delay routines were being calculated based on a 4Mhz crystal not 20Mhz. V6rc3 = Changed BCD to ASCII routine to improve the way the unit deals with non numeric characters. V6rc4 = Modified the LCD initialisation routine to more closely match data sheet attempting to resolve incompatibility with Samsung S6A0069 display controller. V6rc5 = Further changes to LCD initialisation routine to resolve Samsung issue. Rc7a = Removed spurious LCD_Cmd from the start of the main_loop. This was causing issues with the Samsung S6A0069 display controller. Rc7b = Modified Bandwidth code to remove decimal point if bandwidth is 16Khz Rc7c = Added code to switch off bandwidth and BFO info if SSB is selected and display a fixed message instead. Rc7d = Current release. Fixed bug where channel information was not updated in SSB mode. 19/4/2010 Added display driver HEX and source code for 40x2 display. This is a display driver only and has nothing to do with the RA1792 project. Just thought someone may find it usefull. I have just acquired 100 of 40x2 displays and needed to test them. The driver source code is lifted directly from the RA1792 project but only controls 1x display and does nothing else.
