 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Hi folks, I've never had call for it before but thought I better check the that the Bintendo PCB was correctly wired up for the ILI9341 touch interface ... I think it is. However my older ILI9341 module is reluctant to calibrate, e.g. > gui calibrate Warning: Inaccurate calibration Deviation X = -2147483648, Y = -63 (pixels) > gui calibrate Warning: Inaccurate calibration Deviation X = -2147483648, Y = 134 (pixels) > gui calibrate Warning: Inaccurate calibration Deviation X = 450, Y = 143 (pixels) > gui calibrate Warning: Inaccurate calibration Deviation X = 198, Y = 552 (pixels) > gui calibrate Warning: Inaccurate calibration Deviation X = 41, Y = -15 (pixels) > gui calibrate Warning: Inaccurate calibration Deviation X = 153, Y = 370 (pixels) > gui calibrate Warning: Inaccurate calibration Deviation X = -2147483648, Y = 388 (pixels) > gui calibrate Warning: Inaccurate calibration Deviation X = 11, Y = 140 (pixels) > gui calibrate Error : Touch hardware failure > gui calibrate Warning: Inaccurate calibration Deviation X = 272, Y = 5 (pixels) > gui calibrate Done. No errors Deviation X = 0, Y = 4 (pixels) > gui test touch And even when it does GUI TEST TOUCH either does nothing, or plots points in a vertical line down the left hand side of the screen. I have another ILI9341 straight out of the anti-static bag that seems to be fine. Is this likely to just be a case of a (partially) dead ILI9341 ... or more strictly the XPT2046 touch controller ?

maybe the touch 5 wire ribbon cable on the right is not making good contact.try touching it and pressing the display connectors down. there is a gap on mine that closes. if it fixes it, glue it. |
