Issue: 2 bars on LCD screen
Detail:I am using window PC. I bought the Ramps 1.4 kit and LCD form vicious1.
I flashed it with MPCNC511_GLCD, changed the single line of code in the firmware configuration.h. and added u8glib for Arduino.
I have attached the front and back view of the LCD and how it connected to Ramps. I have tired turning the contrast and switching cables but they wont work. No error during flashing. Is there anything I missed ?

Can you post pictures of the cables connected to the lcd? There have been a couple that had the connectors soldered to the board incorrectly.June 7, 2017 at 1:14 pm #35399
There are the photos. There is a problem on uploading picture.Sorry about that. Thanks

I don’t think that is the full graphic LCD, but just the smart controller. I think you need to uncomment REPRAP_DISCOUNT_SMART_CONTROLLER for that one.June 7, 2017 at 1:39 pm #35408
Thank you, Mike and Barry. It is a low-level mistake. Now it works great.

No worries! I’m a newb myself, in the process of printing parts, but have made it through testing of ramps, lcd and steppers, so I knew just barely enough to comment.June 8, 2017 at 7:17 am #35436
LOL. It took me two days to get it working. I guess kind of long…… I mostly learn from try and error.
