Hi, I'm trying to finish my hardware CCPs and I have all buttons working except the zoom (+ & -) and Mem 1,2 & 3 buttons. Using the dataref tool I can see that these are classed as non writable and all other buttons are writable so I presuming this is why I cannot operate them. Q1. Will this be the reason? Q2. Is there a way round it? Q3. Could they be made writable? (if indeed this is the issue?)
Any help or guidance appreciated.
