I'm very new to the ARDUINO environment.
Programming in general,
Sorry if my questions are beginner's questions (my desire to be one of the experts here)
I'm after a successful sketch of power buttons on a 2.4-inch display panel
2.4 "TFTLCD SHIELD (ili9340) mcufriend library
Runs on UNO board. Excellent
Runs on the Open Smart UNO R3 Air board. Excellent
Now I thought to myself that it is possible to run on a 4 "TFT touch screen
(4 "TFT SPI 480x320 V1 / 0 RED)
But fails, it is clear to me that I do not understand and can not define what each PIN its name, what each PIN role (who is PIN DATA?) What is the function of resistance of a screen? Who PIN analog? Who is PIN Digital?
I can understand that a 4 "screen works on 3 or 4 PIN DATA, but it is not defined who are out of 6 available (available - D2, D3, D4, D5, D8, D9 - on a 2.4" screen) Who are the four who transfer DATA to CHIP ST7796S? (From ARDUINO to a 2.4 "screen I can use for a 4" TFT?
Is it SDI (MOSI), is it PIN READ? Or WRITE?
Who are 2 PIN Digital (touch screen voltage?)
Just too complicated, I do not want to give up on it - I am drawn in like a swamp and can not let go until success.
Please help with my project. Thanks for any kind of help.
