Hi for quite long time I worked with IDE1.6.5 Beta version. I have noticed 1.6.5 is not supported anymore so I installed the released 1.6.11. Here the problems came. All old programs do not run. So far experience 2 problems:
Warning problem: " fail to open sketch:"c:xxx\ filename.ino"
Problems with the: "LiquidCrystal_I2C" , only partial information displayed on the LCD 16x2
I replaced boards and boards type, lcd's I tried to load new program with the 1.6.11 and copy the downgraded files with no help....
does anybody experience such problems (xxx.ino and lcd libraries compatibility?) Thanks
