stm32f1 and spfd5408 dont work, only white screen

[DanikVodopianov]

Hi. can you help me with your lib, i run your examples, but it doesnt work, only white screen, i checked pins, all connected right

It's to know the model number of the chip used for your TFT module that you should do first.

Arduino
https://github.com/prenticedavid/MCUFRIEND_kbv/blob/master/examples/LCD_ID_readreg/LCD_ID_readreg.ino

Raspberry Pi
https://github.com/nopnop2002/lcd_id

It's the same outward appearance, but mcufriend has a lot of variations.

And Sailor's information makes a mistake in most cases.

i had this output

e.g. the ID is at readReg(0)
or as a sequence of 8-bit values

so i have ili9327 driver?

but then i tried sketch from another issue and the output is

TFT size is 240x320
identifier=49344
Unknown LCD driver chip: C0C0

[nopnop2002]

This is real pfd5408.

Your LCD is the one I don't know.

Your TFT may be ILI9340.

reg(0x00D3) 00 00 93 40 ILI9341, ILI9488

But it's not support.
