Loboris, Thanks for writing this library. Its pretty nice.. I am using ST7735R with esp32. My issue is, all the chars are printed reversed. I am using your demo and TFT_print() to print the string on the screen. I am not sure what is wrong with my setup. Thanks.

I'm having the same issue with the wrover kit v3 with the ILI9341 display.

jjfretired commented 6 years ago

The ILI9341 expects big endian and the esp32 board is little endian. Their may have to be a conversion to the file/image before it is sent to the displayed. I have no solution at this time.

I changed #Define TFT_INVERT_ROTATION1 = 1 to 0 in tftspi.h and it printer correctly.

@jjfretired It works for me too. I was tried changing the endianess in commands but did not work. Thank you for letting me know.
