All, I have been searching for an algorithm that will tell me which byte in memory to write to, and which bit to turn on or off, to display my data in graphical form on an LCD panel. I used to have one that might have worked, but I'll be danged if I can find it. Does anyone here have anything that I can use? I want to plot my incoming data to the lcd sort of like an oscope. I'm not asking for software to do this function. I really want the algorithm so I can write my own software specifically for the purpose. If anyone has anything I can use, please let me know. My email address is jim@jpes.com Thanks and Regards, Jim -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
