Choose a display... (GLCD/colour) with touch?

[MJU20]

I'm looking for a (cheap) display to show some results of a measurement.

Now I'm using a (cheap) SSD1306 monochrome 0.96" display and this nearly can show everything I want.
But I want to upgrade Colour! YEAH!
And slightly larger then 128*64 pixels.

But there are some questions before I ask China to send me some.
- I'm thinking of using an ILI9341 display is this the same as ST7735? Displays on Ali..ss mention this the same with "ILI9225 ILI9341"
- How can I with, for instance the ILI9341 macro use multiple colours on the display? I see only parameters in the component macro for foreground/background colours. How can I print several things in different colours?
- Is there a simple (cheap) display recommended with touch capability that will work with a ESP32?
- What component can I use to use the touchscreen?

More questions to come...

Hi MJU20

Here a info about the color. Its working also in the simulation

Just set the front color before you print a text, line or circle.

Hi MJU20!

"Better late than never"

Hereby as promised. The "Standard " examble is one I use as startup when I make a new project, then I know the display working correctly and config and connection is ok. When this is done I begin to build up the project and rename the new project.
In the comment in the beginning you can see how I have connect the display. If you enable or disable the macro touchtest. When enable the display show the X and Y coordinate when you press on the display. And of course you need to have a display with touch.

The "KoreCompStort Disp" Is a project I have made to help me everyday. In my work I drive a lot so I have to registre my driving time, km and working time. I use it every day.
Please, I am sure someone will say this could be done easyer, so don´t laugh
Hope this can help you a little in your project and maybe you find the "ligth" and you can copy. Remember first time you compile, it take a while. These display work well with ESP32 and FC9.
