Last time I touched Basic programming language was in the late 70's. There is not enough neurons left today ( I am 74 YY ) to retain a four pair of dozens assembler instructions! Some one told me try " mel pic basic ". I went through the intruction of the Mel Pic Basic and thought I would give it a try to develop some simple Amateur Radio applications as the instruction are still understood and remaining in my old brain...but YOU PEOPLE FRIGHTENED ME a bit reading this thread.... So, shall I go on, buy the STANDARD version and proceed. Need rs232 protocol to communicate with other Ham programmes on PC who run under VISTA...! A lcd screen prefered to show part of configuration of the interface, and showing for some functions what it is doing in real time. Thanks for a shout, and as I request often, dont tell Shakespeare about my bad English, Willy would'nt appresciate.
