I am having a Spider mainboard, newest firmware, and the character display (HD44780 module from GHI). Nearly all sockets are full of modules, including T35, J11D and more.
The character display works most of the time, but sometimes it just goes into a bad state, all characters are move to the right, or it goes into a REALLY bad state where everything is messy and does not look like characters.
I have seen other user mess with the driver, and I have tried adjusting the sleeps to be slightly longer, but it does not stabilize it.
Thanks, I learned it the hard way. Making sure the display is only accessed from one thread did the trick. It is a really slow display, so the probability for cross accessing is big.
When is the next generation of the character display due?
