The only additional connection is to the F_CS chip select pin on the display. Peter, would putting a 25Q on these panels then allow an "in-built" touch calibration to be made permanently available, say on page 1, rather than having to re-calibrate when e.g. firmware is updated, libraries erased, processors changed etc. Greg
