PROBLEM - TFT display AND multiple SerialPorts on Uno R4 Wifi

Official Hardware Classic UNO R4 WiFi
1

im having problems with R4 Wifi too,

i can't make the TFT ( touch screen display ) to work : Compilation error: "wiring_private.h: No such file or directory"

But it works on R3 ( but R3 has no wifi )

And then i can't seem to use more than one softwareSerial.
when running PM2.5 sensor and GPS sensor at the same time ;

If i declare pmsSerial.begin(9600) FIRST, the GPS part will not output anything if i declare gpsSerial.begin(9600) FIRST , the PMS(pm2.5) part will not output anything So i applied this https://docs.arduino.cc/tut.../communication/TwoPortReceive/

on arduino Uno R3 and it worked but when i apply it to R4 Wifi , it says

"class SoftwareSerial' has no member named 'listen'. "

Do you think using ESP32 The ProS3 would solve the problem ?
I love arduino as a beginner but im beginning to feel that it has many limitations. I have formal background in programming but not electronics

Hi. thanks for your reply.
Regarding the TFT :
I am using this https://shopee.com.my/LAFVIN-2.4-2.8-3.2-3.5-Inch-TFT-LCD-Touch-Display-Screen-Panel-320x240-SPI-Serial-ILI9341-Compatible-with-Arduino-UNO-R3-Mega2560-i.365942974.21912366903

2.8 inch

Regarding the Software serial, you mean on R4 there are 2 serial ports ?
I just need to connect them to pins 0 and 1 , and then in the coding use Serial1 for pins 0 and 1 ?

Back to the TFT. I'd be glad if you could suggest an easier to use, compatible TFT with R4. Cost is also an issue. I need to do prototypes real fast so it's a balance between Cost and Ease of usage.

Like for example if it's easier and cost effective to use a different dev. board ( maybe ESP32 The ProS3 ? Introducing the ProS3 by Unexpected Maker - i think they have three serial ports )

I'm relatively new to this ( electronics ) but have some formal education in programming.. humbly saying - not that i am good at it :slight_smile:
THANKS
