I have been advised that the code must be terribly corrupt by the number of errors so the person wanted me to delete the EFIS file and re download and install that file. I have done that several times and it gets no better. I will just start over again and try to get the pieces of the sketch to work one at a time. and return for the answer to errors I can not find explanation for. Thanks for the help so for. By the way I do have the display working some of the time and it seems to be with the code being corrupt some times. The resistor that controls the contrast needs to be adjusted when I do a different install too . Strange to me. I have tried to remove and purge all the IDE programs I have downloaded but keep finding remnants of the program from earlier versions. I am using 1.8.5 but find comments about 1.6.21 in the compiles. Is that a common thing?
