#NuttX RTOS is bundled with #LVGL 7.3.0 ... But latest version of LVGL is 8.2.0 ... And LVGL 8 is NOT backward compatible with LVGL 7 🤔

#LVGL Demo runs OK with ST7789 Display on Apache #NuttX RTOS! 🎉

#NuttX's #LVGL Demo App inits the ST7789 Display, renders some widgets and handles LVGL Events

Let's test the #LVGL Library and Demo App bundled with Apache #NuttX RTOS

ST7789 Display Driver feels laggy on #BL602 #NuttX ... Hope to fix this with SPI DMA

Why is AAAA pink? Because ST7789 Display encodes colours as RGB565 ... 5 bits of Red, 6 bits of Green, 5 bits of Blue

#BL602 only talks SPI Mode 3 to ST7789 Display ... Wonder why 🤔
