I spent hours and hours tracking it down and found the answer here GUI_BMP_Draw() emWin5.36 works but GUI_BMP_Draw() emWin5.46 not I suppose the good news is that I did go learn a bunch about Bitmap BMP files.

  • In the emWin documentation it says that GUICC_565 = BGR GUICC_M565 = RGB In the IL9341 documentation it says Memory Access Control 36h bit D3 is BGR... and D3 = 0 = RGB Color Filter Panel D3 = 1 = BGR Color Filter Panel. I can see that when I initialize the screen that emWin sends 0x36 0x20 .. .in other words it sends D3=0=RGB Then I can send Read MADCTRL 0b and I get 0x20 So the emWin write appears to have worked. Given all of that it seems like it would be correct to pDevice = GUI_DEVICE_Creat…
