Once you get those coordinates what exactly do you do with them?
Thanks for the response Ian I really appreciate it. I have never used this touch controller One other thing when you press the touch wait mS before you read x and y, the ads may do this for you, as the reading settles and changes position.
Hey guys, I could use a bit of help. Calibration is a bit odd. Oh wow, that’s cool.

I have tried to break it apart a bit and understand it: Or do I average the offsets of the center and corners and use that as the “overall” offset? Welcome to our site!
Articles Top Articles Search resources. I’ll try working on it a bit more later today, but your response raised a few questions more questions: Qds7843 Transformer Started by ncag Today at 7: Even when it IS placed properly, this can happen.
I found that the touch panel tilts slightly so linear calibration isn’t the best way to go.

To participate you need to register. I then check to see which map function I should use and if falls within a certain range I use the center offset that I have stored subtracts 40 and 30? Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at From the example I am working off of, I’m a bit confused as to when I actually get the Vatasheet and the Y data and how it works.
Do I just add or subtract in this case the amount it is off by, and for areas close to the center use that offset and for the corners use their respective offsets? It can sometimes be a little crooked as datasheeh My last question mainly deals with the calibration.
Well, I’m stuck with this controller for now, heh. Datasheeh have 4 calibrations 5 point calibration If your touch panel doesn’t tilt you can get away with 3 points Click here to register now.

Ouch, I can see from the above picture how mechanically the touch screen can sometimes not be properly be placed over the LCD screen, thanks for clearing that up as well. If I’m not mistaken, how it works is read datsheet X and Y and using if statements check to see if it falls into a certain range and then use one of the map functions that contains an offset for the corresponding range?
Micro New Member Apr 9, But to make the most of it I calibrate 4 parts instead of one Also, thank you for clearing datashedt the A2-A0, looking wds7843 at the data sheet it makes a bit more sense. I make my own You must log in or register to reply here. The first thing you should be doing is displaying the raw data Readx and Ready Do you use the uC’s builtin ADC to do this?
