With the 'showBMP_not_Uno' MCUFriend sketch I noted about 8.5 sec to display a full image (24bit bitmap with 320x480 size) on a 3.5" TFT using the emulated SPI interface.
I was happy to see the image, but quite disappointed by the time required.
Someone can confirm that this timing is correct or should I expect something better?
Have you tried Hardware SPI?
No, i'm not intersted in HW SPI. I just wish to know from people using this configuration if the time I get is 'normal' since I have some doubt about the TFT /SD HW.
