How to access LGFX using 3.5 TFT Arduino Shield?

[dnovx]

Hi guys, I've been a LGFX user for quite a while, but I'm now having trouble using a 3.5" TFT LCD Arduino Shield, because I'm looking for an LCD that can support 8-bit parallel lines to get optimal FPS results on the LCD when using LGFX, but now I'm having trouble accessing the 4-wire touchscreen that is accessed via ADC, has anyone used this before?
Is there a solution? Thank you🙏🏽

hi,

please have a look at this user configuration for the parallel part

as for the touch, if it's a XPT2046 there are a few examples, otherwise please provide more info

the LCD TFT 3.5" shield for arduino doesnt have ic controller for the touchscreen, only just using 4-wire analog that connected to the pin that already used for 8-bit parallel connection. but i dont know how to access it using LGFX

The LCD doesnt have XPT2046 controller.

provided none of those 4 pins are shared with another device, you can try to apply this
