I'm trying to get working code from STM32CubeMX on STM32F746G-DISCO board. I'm using LwIP TCP/IP stack (which works fine - obtains IP address over DHCP) and STemWIN GUI library and there is the problem. LTDC has been properly configured but when I try to use any of STemWIN functions nothing happens - getting black screen. I'm using latest version of STM32CubeMX and SW4STM32. Maybe someone has working demo project with stemwin and lwip? Or someone know what is wrong with automatically generated project?
