Hello! First of all, I want to say hello to everybody since this is my forst post.
I have a problem related to an LCD. I am developing a battery-powered datalogging application, and most of the time, the LCD connected to the device has to be turned off. When a button is pressed, the LCD has to dysplay a message. Therefore, at the time the LCD is powered off, I put the port driving it to High Z Digital, and just before having to display the message, I make the port Strong Drive. However, the LCD does not show the message correctly, or not at all. the program halts here, and semms to remain in one of the LCD functions. When I do not change the GPIO drive mode, everything goes fine.
Does anybody have an idea on what could be wrong?
Thank you!
