Connecting 2.8" TFT through RAMPS 1.4

Using Arduino Displays
1

Hello,

I recently have bought Adafruit 2.8" TFT, and would like to connect to Arduino through RAMPS 1.4.
Considering the speed, I am trying to do it with 8bit interface.
I succeeded in connecting and using it when I directly wired to Arduino, but I failed when I wired TFT to RAMPS 1.4.

I have referred the pin numbers and mapping of RAMPS 1.4 and tested with same pins for each case.
I do not understand why I cannot use same code for both cases, since I wired to pins in RAMPS 1.4 which are exactly the same of Arduino. Do I need to do something additionally?
Is there anybody who has succeeded in using TFT through RAMPS 1.4?

Thank you.

I have solved it. :slight_smile:
It was related to how the soldering was done.
In addition, the pins for RD, WR, CS, CD do not have to be analog. It can be digital.
