Някой който се е борил с STM32 и TFT LCD случайно да знае как може да се завърти изображението на дисплея. Всичко се изобразява само вертикално. Никъде в никакви документации, библиотеки или хелпове не открих да се споменава нещо подобно.
STM32F103VET6 и диплея е 2,4" / ILI9341 вързан по SPI. Всичко дотук работи без грешка, (ползвам Keil), но не предполагах, че тази ориентация ще се окаже "подводен камък". Два дни не мога да открия какво ми убягва
