Cathodion Posted August 14, 2012 at 05:25 PM Share Posted August 14, 2012 at 05:25 PM Hey folks, I'm having trouble with my LCD20x4 after upgrading the master brick firmware to the latest version today. After a certain amount of time the backlight is somehow disabled, and the LCD no longer responds to any commands send from brickv or my Java program. The buttons are still functional thought! I can see brickv reporting "pressed" and "released" when i press the 3 buttons. There are no errors reported by either brickv or the running Java program. When i look closely to the LCD I can still see the text that it was showing last, altough its hard so see with the backlight off. The master brick (1.1) is running version 1.2.4 of its firmware, and the LCD bricklet has firmware version 1.1.0. 3 other bricklets connected to the same master brick still function like they should, so it looks like an isolated LCD problem. When I hit the reset button in brickv the master brick restarts and the LCD work again, only to freeze again after a seemingly random period of time. I hope this description is informative enough to locate the problem. I'm trying to create a reproducible scenario that triggers the problem. Kind regards, Geert Schuring.
