Once you have the library installed, restart the IDE. Now from the examples->Adafruit_FT6206

menu select CapTouchPaint and upload it to your Arduino.

FT6206 Library Reference

Getting data from the touchscreen is fairly straight forward. Start by creating the touchscreen object

with

Adafruit_FT6206 ts = Adafruit_FT6206();

We're using hardware I2C which is fixed in hardware so no pins are defined.

Then you can start the touchscreen with

ts.begin()

Check to make sure this returns a True value, which means the driver was found. You can also call

begin(threshvalue) wish a number from 0-255 to set the touch threshhold. The default works

pretty well but if you're having too much sensitivity (or not enought) you can try tweaking it

Now you can call

if (ts.touched())

to check if the display is being touched, if so call:

TS_Point p = ts.getPoint();

To get the touch point from the controller. TS_Point has .x and .y data points. The x and y points

range from 0 to 240 and 0 to 320 respectively. This corresponds to each pixel on the display. The

FT6206 does not need to be 'calibrated' but it also doesn't know about rotation. So if you want to

rotate the screen you'll need to manually rotate the x/y points!

The touch screen is made of a thin glass sheet, and its very fragile - a small crack or break will

make the entire touch screen unusable. Don't drop or roughly handle the TFT and be

especially careful of the corners and edges. When pressing on the touchscreen, remember

you cannot use a fingernail, it must be a fingerpad. Do not press harder and harder until the

screen cracks!
