I have finally got round to changing my LCD control software to 4bit operation so as to use fewer port pins and in doing so it occured red to me that it would me very daft to have an LCD display and not use it for the main function menu (I was planning on having a bunch of LEDs give out a binary number and a control knob to select the mode but on reflection that’s just stupid!!). So once again is back to the coding/drawing board. Mind you had I thought about it before maybe I wouldn’t keep having theses little drawbacks….
