Fixed ghost input tft screen by second rules #18

Closed lucableve closed 8 months ago

lucableve commented 9 months ago

I and others have experienced ghost input issues when changing the original flat cable with a longer one, causing interference with ghost inputs that lead to significant problems during printing.

The reference to the issue is here: https://github.com/bigtreetech/TFT35-SPI/issues/15

I have updated the driver, now managing the RT calculation using the second formula, which involves the use of the Y plate, implemented similarly to the X plate.

After a week of testing and various fixes, the result is stable and functional. Occasionally, ghost inputs still occur, but addressing them would likely require hardware intervention or using the penirq, also documented in the touchscreen datasheet.

I stand corrected. @OstroMa points out that he is using the original cable
