Break the problem down into easy bits. Create a routine that will drive the 154 by looking carefully at the datasheet and seeing which lines need to ber pulled where. Same for the display. Steve Hi Steve, Perhaps I should better explain my problem. I am able to get the data from the MAX154 and convert it to what I need. I am also able to write to the LCD module. The problem is try to get BASIC-31 to allow me to write the converted data to the display. I have tried the $(0) command with no success. It only allows me to enter a set value. Not a variable. XBY(0ff81h)=ASC(A) just outputs the letter "A" also. I have used a technique where I have it GOSUB a lookup table. But that involves looking up one decimal position at a time and get rather crazy and long. Not to mention slow. Any help would be greatly appreciated. Thanks! |
