OPEN-SMART HX8352B with ESP32 and MCUFRIEND_kbv

Other Hardware Displays
1

Hi guys..
i have a new display, an OPEN-SMART HX8352B, that works fine with a MEGA2560 and original library, attached here.

but it is too slow and i need a reactive display. esp32 is the right choose i think..

waiting to use esp32 with this display, i tested it with MEGA2560 and MCUFRIEND_kbv library.

LCD_ID_readreg with MEGA2560 give me this response:

Read Registers on MCUFRIEND UNO shield
controllers either read as single 16-bit
e.g. the ID is at readReg(0)
or as a sequence of 8-bit values
in special locations (first is dummy)

The current Release of MCUFRIEND_kbv does not work properly with OPENSMART HX8352B
The Beta on GitHub does work. I intend to issue a new Release soon.

I have not any intention of supporting OPENSMART boards on a ESP32.
If you want speed with OPENSMART, buy a Uno.

I strongly suggest that you remove the OPENSMART_TFT folder. It contains a hacked copy of an obsolete MCUFRIEND_kbv library. I would not mind if they had chosen a different class name. Arduino will be confused if you have two different versions of MCUFRIEND_kbv
