do you have the full spec? If not fotget it! You will need quite some info (what is the required command sequence, which touch controller is used and how does it communicate, ..), so without a spec you wont be able to know.Hello,
working on project and need to use a Touch screen.
Never used one on a RPI.
I found one that fits requirements (dimensions mostly 150-180mm x 30-60mm), has the following specs:
3.99 inch LCD screen 40PIN resolution 400 * 960 with capacitive TP long strip screen RGB interface
Product name: TFT touch screen
Product size: 3.99 inches
Resolution: 400 * 960
Perspective direction: full view
Driver chip: ST7701S
Interface type: RGB
Physical size: 42.5 * 102.08 * 1.9 (mm)
Display area: 39.18 * 94.032 (mm)
Number of pins: plug in 40PIN
Working voltage: 3.3V
Working temperature: -20~+60 ° C

Not sure if this would be supported by the RPI (working on RPI4 and getting RPI5).
I know that via HDMI would be easier but since it's an industrial project is not possible eventually.
Any idea or even suggestions for a different touch screen? Dimensions must be similar to above, maybe a bit larger too.
Thanks
That screen uses SPI interface and RGB. You will need a driver for the ST7701S which uses the SPI for commands and DPI for display data. Sorry, don't know if the driver which is in the tree allows for that, so will leave it with you to check.
What's your level of experience?
