GC9A01 and Arduino Mega

[czelek]

Hello, first of all thanks for this lib! Can I use it with GC9A01 and Arduino Mega?
So far I can see only backlight.

I tried combinations:
First one:

VCC -> 3.3V
GND -> GND
DIN -> D11
CLK -> D13
CS -> D10
DC -> D7
RST -> D8
BL -> D9

Second one:

Vin -> Vcc
GND -> GND
GPIO 9 -> CS
GPIO 7 -> RST
GPIO 8 -> DC
GPIO 11 -> DIN
GPIO 13 ->CLK
GPIO 6 -> BL

I tried with and without 2.2 resistors.
I have some warnings during compilation also:

GFX_Library_for_Arduino/src/Arduino_GFX.h:49:0: warning: "PINK" redefined
define PINK 0xFC18 ///< 255, 130, 198

Thank you!

same as ili9341, you need some resistors

I used 2.2k. For 6 pins (not for vcc and gnd). Is it working with Arduino Mega? Could you write which setting of wires is Ok? Thank you!

I am using 3.3k: https://www.instructables.com/ArduinoGFX/

Ok. I will try that! Thank you

Unfortunately it isn’t working. With 3.3 k rasistors i can see only backlight same as without it. Could you write what wires connections i should use?
