Hi Ben

I use a touchscreen with a FT6336U controller and it's working if I use Touch Index Range 0.
The touchscreen give the coordinate back, but for x max 24 and for y max 22 if i set to 360 pixel touchscreen.

If I set the touch index range to 1 it' give back always 0

I can very easy use the touchscreen with index range 0 but is this the way?

I did not found a information about Touch Index Range in the help.

Hi Stefan,

The touchscreen should be able to detect up to two simultaneous touches to allow for things like pinch gestures, the first touch being in index 0 and the second being at index 1. So index 1 should have data but only when you have two fingers on the display.

Hi Ben

Ah it's like this.
One more little question. I have a 320*240 display and the touchscreen set to the same values. The touchscreen gives me 24 for x and 15 for y as the maximum touch coordinates.
This is very useful for evaluating a key, but is that ok?

Hi Stefan,

That seems a bit low, what if you change the single ended/double ended property to see if this improves things at all.

Hi Ben
Single/double made no change
I2C hardware/software and speed made no change (always working)
But if I double the number of x,y pixels, the result also doubles.
If I use 30000x,y pixel the maximal result is about 2336,2048

just like the display: Is it possible to expose the "send/get reg and send/get data macros"?
I like to try if gesture is working in a way

gesture

Hi Stefan,

I've now exposed the Read and Write bytes macros for you that allows you to read and write the register values.

Hi Ben

Thanks a lot.
I've read the gesture register but this is always 00. I've googled and many have problems with it. I keep looking.
I also read the X position and this is a maximum of 320 pixels and independent of the component x size propertie.

Stefan
