I have a 7" tft with SSD1963 chip, see ScreenBack.jpg, and would like to get it working on a Mega. I found a post that gives a connecting diagram, see diagram.jpg, but not all names of pins correspond to the diagram. More specific my screen has pins like LED_A, T_DIN, T_CS, T_CLK, etc, see Connector.jpg
I understand the 5V pin is for backlight, but when I apply 5V to that pin from an external source, and ground to ground of course, there is no backlight. I suppose that has to do with a jumper that I need to solder, see backlight.jpg.
My questions are:
How to wire this screen (directly) to the Mega?
Can this screen work with the MCUfriend_kbv library from David Prentice? This because I have my project currently running with a mcufriend 3.5" screen, that works very well with Prentice’s library, and I would be happy if I would not need to rewrite the entire code to correspond to another library.
If yes, how do I initialize the screen in the code?
If no, what library to use, and how to initialize the screen in the code?
How do I get the backlight working with PWM? I suppose I apply 5V to the 5V pin, ground to ground, but where to apply the PWM signal? And how to solder the jumpers as on backlight.jpg?
If anyone could help, that would be very much appreciated.
