Hello, guys.I'm trying to get started with a TFT LCD.4.7 with the ILI9487 driver.And I have some problems.

First of all, a couldn't find any library for the driver I have.

Next is that I can't find any resources that explain how can I write my own library,

And the last is that there are some libraries that support other drivers like SSD1968 drivers, what's the difference between these drivers and libraries?Can I use for example SSD 1968 libraries instead of my own LCD driver?

Hello after a lot of search and efforts found a library that is designed for an ARMed base Arduino library, but unfortunately, i haven't ever worked with Arduinos..Would you please help me port the library.I just don't know some basically things about the library ive found.

In the file attacthed there is a read me text that talks about the pins.It has mentioned that D0_D7 that are datas are digital and the RD, WR, CS, RS, RST are analog!!!

How can it be possible?We use WR,.... to send the tft a cmd orother digital pulses.Does it mean that i have to initiallize these pins as ADC pins?

On the shield connector they are GPIO pins that are capable of analogue or digital connectivity, the pin on the CPU having an ADC configuration available.

In the case of RD, WR, etc this will be driven as GPIO digital outputs.
