Hi everyone need help.

I take already built bin from github https://github.com/cbm80amiga/ST7735_SDinfo_stm
Connect ST7735 lcd display
But I have only white screen and nothing else.

you need to mention the core and the board that you used
https://github.com/stm32duino/Arduino_Core_STM32/wiki
viewtopic.php?t=3
viewtopic.php?t=301

and normally, simply taking codes from github may not run out of the box
e.g. that you may need to change the pin references for the pins used for SPI and LCD pins etc.
they should normally have symbols of PAxx, PBxx etc

I knew about core . Ioc where I can Manage pins,
Its needed if I do it via cube ide or keil

I take already built. bin

And if look where all project did on stm32duino... That means that we re not needed ioc, only bootloader pc13 and scetch if we do it in arduino ide
