Support for ILI9325/9328 and HX8357D

[dumtux]

I could use this library for 3.5 inch TFT LCDs with ILI9381 driver.

I also want to use 2.8 inch Arduino TFT LCD Shields. I bought two different shield.

• TFT Shield with HX8347D
• TFT Shield with ILI9325/9328

I am seeing those driver ICs are not supported by TFT_eSPI yet.

As these TFT LCD shields are very cheap, I'd like if this library works with those displays.
Any plan to support these?

It is possible to add new drivers to the library buit without a display to test them on this tends to be a rather troublesome activity for me to do. Maybe someone else can help.

For a temporal solution till TFT_eSPI supports those driver chips, MCUFRIEND_kbv can be used.
It supports all those above (HX8347D, ILI9325/9328).

But it's slower than TFT_espi.
And the worse thing for me was that I couldn't make MCUFRIEND_kbv work with LVGL.

@Bodmer how can I send you a TFT 8347i, for help you to help another people?

[dumtux]

I also have HX8347 and ILI9328 displays unused.
After a lot of tries, I decided to use ILI9341 LCD and already designed my product with it.
If possible, I also would like to ship my HX8347 and ILI9328 LCDs to your address. (Of course if @Bodmer has time to work with those)

@Bodmer I don't know to program in low level, with many dificulties i try to learn how to program, I want to help the community, please let know if we can send you this screens, or who can receive it for make better the TFT_eSPI library.

Thanks for sharing your knowledge, your pattience, your time, your strength and your affords.

Somehow it works for me with ILI9328 LCD driver (as detected by adafruit LCD library on uno), on NodeMCU 32s i tried a lot of things but finally the below two changes made it work: 1) using 3.3v instead of 5v 2) Uncommenting the first "#define TFT_PARALLEL_8_BIT" line number 33 also

default ILI9341_DRIVER was used .. parallel connection
If anything, do ask as i am working on it now ..

In my experiments, ILI9328 LCDs did not work with ILI9341 drivers.
Could you share a close picture of your LCD module?

[amitgithub1]

There doesn't seem to be any 5 to 3.3v ic behind the screen pcb.
Any suggestion where i should send the pic for reference?

A couple examples are working except touch based, which i am not able to run seems parallel lcd do not have touch support here.

Hey, I am very sorry, there seem to be an confusion at my side, i had ordered two LCD together, again rechecking i find that both are different driver. Will update if anything works.
