LK204-25 Display Locks Up and Freezes
LK204-25 Display Locks Up and Freezes
Hello,
I've got about 20 LK204-25 displays that I know, over time, the couple that I've tried are locking up. The display will freeze with the last information that was sent to it.
-I'm using a Philips Micro LPC935 to drive the display.
-I'm using the I2C.
-Not using the GPO's.
....However, the Micro continues to work and I am able to continue without a problem except that the display stops updating.
I've checked to make sure that the data transmission is still alright going to the LCD display and it is.
Could this be a grounding issue?
Any advice would be great!
Thanks,
Jason

Miles,
I would say it's about 6 to 8 inches from the controller to the display.

It locks up random....anywhere from 2 minutes to at least 1 hour.
A significant drop in voltage may cause a lose of communication...Depending on the hardware involved, I have seen instances were 2.5 Volts on the SCL line will cause havoc, however in other causes it works fine...
Have you played with resistor values...strengthen or weaken the pull ups will affect communication...
