#Multitouch monitor test serial

The problem is that it dont prints the XY Values correct. Tft.print('Hello') // just to see to the alignment / rotation Tft.setTextColor(WHITE, BLACK ) tft.setTextSize(4) Tft.fillRect(p.x, p.y, 2, 2, YELLOW) // draws 2 pixel rectangle TouchScreen ts = TouchScreen(XP, YP, XM, YM, 300) TSPoint p = ts.getPoint() //Get touch point TouchScreen ts = TouchScreen(XP, YP, XM, YM, 300) // Resistance between D8 and A2

const int TS_LEFT=918,TS_RT=98,TS_TOP=75,TS_BOT=901 Īdafruit_TFTLCD tft(LCD_CS, LCD_CD, LCD_WR, LCD_RD, LCD_RESET) This is Sketch I wrote to test the accuracy of the touchscreen: #include I ordered a new display just to check if there is an fabrication failure. I´m still a few Pixels off but a bit closer than last time.

I ran the calibration and the paint sketch again and adjusted the values in my Sketch, that I get from the Serial Monitor. Is this a fault on my own where I don´t hit the corners accurate enough, or are there Issues known thats just a simple production failure? If you need any pictures or the sketch I use, I can upload those too.įirst off all, thanks for the reply. About a year ago I made a UI with an 2.4' Touchscreen and never had any of this problems. I calibrated the Touchscreen a few times with the test from MCUfriend and the one from Adafruit. Therefor on the Top of the Display the Screen reacts to the stylus, although the border of the LCD is about 3mm underneath from that point. I also noticed that the last 2mm above the bottom from Display don´t react to the stylus. My problem is that I have a offset of about 6-8 Pixels in the Y-Direction and about 2 in the X-Direction. I wrote a Sketch that just draws a little rectangle whereever the Screen gets touched. I`ve got it hook up on an original Arduino Uno. displaying the image at the size specified by the input signal.I´m struggling around with the 2.8' Touchscreen I ordered last week. For information about EIZO’s pixel policy see our Warranty page.Ģ Gamma can be confirmed with dot-by-dot display only. Start EIZO Monitor Testġ Pixel warranty varies by manufacturer. You should also clean the display prior to testing, since reflected light could cause dust particles to look like defective pixels. In order to ensure meaningful test results, your monitor should already be warmed up prior to testing (ideally for 30 minutes). This allows you to precisely assess even dark image areas. It is recommended that you carry out the monitor test in a dark room. For this reason, please note the manufacturer specifications (especially for the defective pixel test). You should therefore always assess your monitor within the context of its respective device category. For example, gaming monitors are distinguished by particularly short response times, whereas graphic monitors impress with a particularly homogenous image display and smooth gradients. The EIZO monitor test consists of various test scenarios that your monitor can handle to a greater or lesser extent, depending on the model. You can check your monitor for defective pixels and get a sense of its viewing angle stability. You can carry out 13 individual tests to check how uniform the image display is across the entire monitor, for example, or if the text is displayed sharply. The EIZO monitor test lets you quickly and easily assess your monitor’s image quality.
