Hi Fist this is unbelievable, Thank you for this library. Please, i need help to make this work. 2 problems.

I have to put "lv_xg.h" i same folder with lv_test_label_1 and then it compiles.
I have RA8875 and couple different ESP32 boards, WEMOS LOLIN32 and Adafruit ESP32 Feather, i'm having hard time to connect RA8875 with any of this boards, lv_test_label_1 compiles fine, uploads fine, but noting is happening. I thing this the pins are
define XG_PIN_DC 16

define XG_PIN_LCD_RESET 17 //34

define XG_PIN_SD_CS 4

define XG_PIN_TP_CS 33

define XG_PIN_TP_IRQ 27

define XG_PIN_LCD_CS 5

define XG_PIN_MOSI 23

define XG_PIN_MISO 19

define XG_PIN_SCK 18

but when i'm checking the pins with oscilloscope, noting comes out of my ESP32 boards, so i don't know what to do. Please help me. Thank you in advance.

patrickpollet1966 commented 4 years ago

Hello,

Did you install the library in your Arduino IDE ?

I ask this question because i did not have to copy lv_xg.h in the same folder as the .ino and it is perhaps a point indicating that something is goes wrong.

On the other point, the pins involved are XG_PIN_LCD_RESET, XG_PIN_LCD_CS, XG_PIN_MOSI, XG_PIN_MISO, XG_PIN_SCK (which are default pin for SPI in ESP32-ARDUINO). If you use this it should works.

momosh13 commented 4 years ago

Thank you for reply. So, After lot off test's i make it "work", The library works only on DOIT ESP32 DEVKIT VI board and this is the wiring pins

define XG_PIN_BL (2)

#define XG_PIN_LCD_RESET (4)
#define XG_PIN_TP_CS (15)
#define XG_PIN_LCD_CS 5
#define XG_PIN_MOSI 23
#define XG_PIN_MISO 19
#define XG_PIN_SCK 18

And now i have this problem, the colors are wrong, please see the attached pictures

Please help me to fix this. Thank you

patrickpollet1966 commented 4 years ago

It's easy to fix.

Edit lv_conf.h and modify LV_COLOR_16_SWAP to 1 like this

define LV_COLOR_16_SWAP 1

momosh13 commented 4 years ago

Thank you, it's fixed ! One more question, if i can? Is there a chance, to run this, on Teensy 4.0? If yes? Help me whit that too. Thank you

patrickpollet1966 commented 4 years ago

There's no code for Teensy 4.0 in the source but it's not difficult to add it. You have to modify XGLCD.h and add defines and specific SPI code for the Teensy. (There's currently code for esp32, arduino, mkr, ...)

Hi Patrick, thank you for your reply. I think I have a power issue. Can you say something about powering of the display?

patrickpollet1966 commented 4 years ago

As i remember it needs almost 1 A to works.

Hi, you must connect all power pins to the board. Regards Patrik

Hello,

I am afraid it's not possible to supply the screen with the 3V3 from the ESP32 board (the internal regulator will not provide enough current). Furthermore I am wondering if the screen does not need 5V in fact. Please check in the screen datasheet.

I just checked my own board (it's a 7" display but it's the same). J8 is open an i provide the supply (5V) from an external power supply as USB may be too weak for the 7", perhaps it may works for the 5".

My TFT 5inch 's J8 status now is short (3.3V). If I remove lead solder at the J8 to open for 5V like
