Discussion - EVE / Re: ST7789V and FT81x - startup

Thank you for the reply.
ILI9488 is the other display I would like to try to use, I had not noticed it had a similar setup to enable RGB.
I believe I have all the correct commands to configure ST7789 for RGB, the datasheet covers it nicely. I will order a few test LCDs and breakout boards.
I guess my only remaining question is the use of the EVE DISP pin and the LCD reset pin. I notice on the ME810A-HV35R an OR gate is used, if I am not mistaken you would need to enable the FT81x, turn the DISP pin on, then reset the display and send the RGB commands via the host MCU?
Would there be any drawback to leaving the FT81x DISP pin float, and allowing the MCU to control the LCD reset independently?
