Anyone had problems the MPLAB Sim with the user data memory variables not getting changed. I worked at first. Actually got the simulator running including WDT and Sleep! I used a watch windows and things were fine, I saw my variables changing. Breakpoints stopped and the output window acknowledged the WDT timed out. I was a happy boy for about an hour! Then they quit getting up-dated along the way? Something went South! Even at the beginning, in initializing there values, they don't change in the watch window? I wonder if I can delete the watch window a start a new one? The addresses show up at the correct Cblock places. I started at 0x08 on the 16F505. The values just down change when you load them? Also, in this part, the user ram is split into 4 banks of 15 plus the small block above 0x08-0x1f I got errors trying to use the upper banks? Is there something I have to do the the FSR to get to locations at 30 or 50 h? Bits 5&6 are suppost to select these banks? I didn't figure that out either. I think I may have to start a whole new project file? Maybe the watch window is botched? I am giving up for now, I already don't like this processor. And I thought is was going to be easy!
