Garbled LCD screens

[Roxy]

Unfortunately for you.... I don't have an LCD Panel or I would jump in and help you! There are a lot of different modules and communication methods for the different panels. It might make sense to see which panels are 100% reliable and compare their interface code against what you have. If you can get consensus on what the most reliable one is... I'll take a look. It might be they have pushed the timing or something a little bit too far and warming over the interface code makes things better. But that is pure speculation.

But that is pure speculation.

That is a whole lot more than speculation, it is years of hands on experience.

OK.... I believe its real.... But it might not be the interface code... I'm just making stuff up... If there is a stack overflow condition or a bad pointer being de-referenced in a loop, you can make all kinds of data corruption happen.... My guess is they are pushing some I^2C timing or something too hard. What happens a lot of time is people make firmware based timing loops and when the processors speed up, the timing doesn't work any more. I really don't know at this point. The good news is, I don't have an LCD Panel to look at... I can just sit here and speculate! What a sad world!
