if possible please support ili9486 in 8 bit mode

RobertoBenjami commented

Please try the ili9488 driver. According to the datasheet, they are very similar.

thank you sir!
it works!
but colors is inverted and can see some vertical and horizontal lines

Upload the project here to watch it.
Increase the delay in the IO driver header

hi dear roberto
please check your email

I checked, it's interesting. Does the display include a touch screen? If so, how many ohms can be measured between LCD_WR and LCD_D7? What kind of microcontroller and what settings is it running? What length of wire is connected? I checked the datasheet of ili9486, it should work fine.

1.Does the display include a touch screen?
NO
2.If so, how many ohms can be measured between LCD_WR and LCD_D7?
NOP
3.What kind of microcontroller?
STM32F103RE
4.what settings is it running?
my lcd has part namber Z350IT002
datasheet
http://aitendo3.sakura.ne.jp/aitendo_data/product_img/lcd/tft2/Z350IT002/Z350IT002_aitendo.pdf
i have set r8 instead of r16 base on end of page 7 on this datasheet(hardware set) using google translate

pin setting:
CS C10
RS C11
WR C09
RD C08
RST C12
D0---D07 C00---C07
D08---D15 > GND

5.What length of wire is connected?
LESS THAN 20CM

i tryed another driver based on stm32duino
https://github.com/prenticedavid/MCUFRIEND_kbv
i sent picture quality please check your email

and found another bug
in ili9488.h file
#define ILI9488_ORIENTATION 1
there is no difference between 1 and 3
also there is no difference between 2 and 4

thanks for the time you spent for a beginner
