Tried tft touchscreen and MCUFRIEND graphics test and enabling drivers in MCUFRIEND library and didn't work Tried running tft.begin with different HEX, 0x9341 did not work either

  1. Delete any manually installed library(s)
  2. Install those libraries properly via IDE Library Manager.
  3. Plug Shield into Uno. All the male pins should engage with the corresponding female header sockets.
  4. Run graphictest_kbv from examples
  5. Copy-paste the Serial Terminal

Please answer each numbered step. e.g. Y/N Describe anything unusual or unexpected problem.

reg(0x00D3) 00 00 93 41 ILI9341, ILI9488

Your readreg report looks 100% for an Ilitek ILI9341V controller. ID should be reported as 0x9341

all libraries atm is installed via IDE library manager, the ' ' for include is for the previous students working on it Shield is plugged properly Graphics test doesn't work one arduino gave ID= 0x2121 Another gave ID=0x101

the ' ' for include is for the previous students working on it I do not understand.

I expect you to use an unchanged library. And a regular Shield. Please post a link to the actual shield that you have bought. Or post a photo of front and back of the shield. Or at least say what colour the pcb is. And the part numbers printed on the visible integrated circuits.

David.
