Very good David, thanks for your answer.
I had read a lot of posts very useful from you, thanks again !!
You confirm that "ili9488" & "r61581" controllers run with UTFT library & MCUFRIEND_kbv library on a MEGA2560.
I could use either one or other with both librairies on both shields
In the UTFT Supported display modules infos, I do not find the "ili9488".
I was a little bit confused with the MCUFRIEND_kbv library because you said somewhere "It will work on a MEGA2560 but not very fast" and it was confirmed later in a previous post. Maybe this library (from you Hi...) is running better now.
With the LCD shield for uno, digital pins 2,3,4,5,6,7,8,9 should be used with the mega2560
With the LCD shield for mega2560, I don't know which pins are used. Is it still a 8 bits parallel or 16bits ? or via serial SPI ??
How the the same library can work with 2 different shields connected differently ?
Where I have to indicate the pins used for the differents LCD Shield in the library ?
I found contol pins definition A0->A4 for LCD_rs, LCD_rd ....... but not the others for LCD_d0..., LCD_d7.
So, I think it will be useful to have the microSD efficient with a TFT if possible
Moreover, in the next step of my project I would like to add my ethernet shield.
I already have this shield (wz5100) and works fine alone with the mega2560.
The ethernet shield uses the SPI pins (50 to 53) via the ISCP connector and pins 4 & 10 for chip select (SDcard or ethernet).
Maybe, I will have to use a couple of external wires if I can not connect them together with the pins
Could you confirm the both shield (LCD + Ethernet) are compatible on a MEGA2560.
Sorry for all these questions but I try to find the best way before to go head and buy the right LCD TFT TouchScreen compatible with the Mega2560
My final project is to be able to send some data (from different probes) to internet and to have a dashboard on a LCD
My sketch with the probes is ok.
Data from probes come via RF433 module. This sketch is ok.
My sketch with the ethernet shield is ok.
I'm able to send all data to the network.
If I can mix every things, I will be happy.
