AM335X: Beaglebone Black touchscreen calibration issue

Naseer Nazar

Hi,

I have install a new sdk with the am335x-boneblack.dts updated for a 4dcape-43T lcd display with touchscreen. The 5 point calibrations results are here and matrix gui pops up. However the touchscreen only appears to work in the bottom screen. Please have a look at the coordinates, they seem ok to me.

Calibrating touchscreen (first time only)xres = 480, yres = 272
Took 70 samples...
Top left : X = 539 Y = 963
Took 44 samples...
Top right : X = 3545 Y = 928
Took 58 samples...
Bot right : X = 3535 Y = 3184
Took 57 samples...
Bot left : X = 525 Y = 3204
Took 61 samples...
Center : X = 2036 Y = 2045
-18.611328 0.126336 0.000674
-23.362000 0.000699 0.076491
Calibration constants: -1219712 8279 44 -1531052 45 5012 65536

I tested a second screen and the results were erratic, ie some pointer steps missed and only 2/3 points calibrated.

Any ideas would be helpful

best regards

I have attached my am335x-boneblack.dts with 4dcape-43T support with touchscreen and backlight on gpio.

Hi,

Does this behavior occur in both cases: on bootup & when you run the ts_calibrate from the serial console?

Have you tried recalibrating your touch screen, after the board boots up:

Hi Yordan,

Yes, I have tried bootup from sd card and manually running ts_calibrate with its environment variable set.

I have tested with compiled build and pre-compiled image.

All cases Matrix touch screen still not working correctly.

Secondary points

calibration using ones finger is not jumpy unike a stylus.

Mouse is working fine

I have also run evtest for the touchscreen, again coordinates system looks ok. I have attached the test with some comments.

Is there another gui application I can try?

Hi Naseer,

Naseer Nazar said:

Not that I know of.

I see you use the same panel parameters (display timings & panel info) as in AM335x EVMSK device tree. Can you double check if these match the display you use?

Best Regards,
Yordan

TI__Guru**** 161600 points

Also, I see that you reserve channels 4, 5, 6 & 7 for adc only, which means that only channels 0, 1,2 & 3 are used by tsc. Can you try adopting the approach used in am335x-evmsk.dts & change the tscadc device tree node to:
&tscadc {
status = "okay";
tsc {
ti,wires = <4>;
ti,x-plate-resistance = <200>;
ti,coordinate-readouts = <5>;
ti,wire-config = <0x00 0x11 0x22 0x33>;
ti,charge-delay = <0xb000>;
};
};

Yi Yordan,

I have tried your suggestions, updated the timings from datasheet. No change to the touchscreen response. The dts file is attached. I used the pre-configured image with this dts file.

am335x-boneblack (2).zip

Hi Yordan,

Here is the ts_calibrate results for the updated dts file

Calibration constants: -2431956 8414 297 -782144 -176 4857 65536

The coordinates appear to be fine, yet matrix gui touch not fine.

Can the calibration constants be checked, are they calculating correctly?

Hi Naseer,
i would like to jump on this thread and ask you a question.
i have also a beaglebone black with a 4dcape-43t display and tried the following:

prebuilt binaries from the ti sdk 2.0.00
copied the am335x-boneblack.dts from your am335x-boneblack (2).zip archive to :
<TI_SDK_HOME>/board-support/u-boot-2015.07+gitAUTOINC+d49aa5effa/arch/arm/dts
<TI_SDK_HOME>board-support/linux-4.1.6+gitAUTOINC+52c4aa7cdb-g52c4aa7/arch/arm/boot/dts
make && make install
copied the new devicetree-zImage*.* , zImage and u-boot.ing on their appropriate partitions / directories on the sdcard.

The beaglebone boots, shows tux upper left , proceeds with the TI log and the progress bar.
But then it does not continue with the matrix application, something like a cursor is shown on the upper left.

Can you give me an advice what i'm missing ?

Thank you in advance and for your dts file from above

Regards
Erich

0 Naseer Nazar over 8 years ago in reply to Erich Bachl

Hi Eric,

I've not tried version 2.00.00 sdk, I didn't know it was out!. The dts file is bare bones, sets up the display timing, touch screen and a simple backlight. Your display seems to be working as is mine. The problem your having as well me I think is elsewhere. A pre-built binary should work with a hdmi display and matrix gui should popup. If you're compiling then "make install" should compile the sgx module for gui to display. Without that it won't display. You get a cursor or login screen only.

So a very small step

I first create the pre-built image on the sd card

I then compile a modified am335x-boneblack.dts file with make linux-dtbs, then copy the generated dtb file onto the sd card rootfs/boot folder.

I will try 2.00.00 sdk, see if it solves the touchscreen problem.

best regards

Naseer

Ps. there is an error in my dts file. The lcd_pins_sleep gpmc_ad8 to ad15 should be removed.

0 Erich Bachl over 8 years ago in reply to Naseer Nazar

Intellectual 420 points

Hi Naseer,
thanks for your answer.
what i found out is that qt applications run with option -platform linuxfb on the command line otherwise it gives an "egl display could not be initialized" error
touch calibration does not work, coordinates have big offsets
i will remove the entries you mentioned i look further

Best regards
Erich

0 Erich Bachl over 8 years ago in reply to Erich Bachl

Hi Naseer,
meanwhile the only problems which are left:
wrong color representation and the calibration is still not working

Have made any progress ?

Best regards
Erich

Hi Yordan,

We have not made any progress on the touchscreen calibration.

Can this issue be escalated please?

best regards

Naseer

0 Erich Bachl over 8 years ago in reply to Naseer Nazar

Hi Naseer,

we have to change the wiring of the adc channels.

See my modified am335x-boneblack.dts. It is not complete but it should point into the right direction

Best regards

Erich

Hi,
another funny thing:
with my dts file in my previous post all ts_test, ts_calibrate, ts_print(_raw) utilities works prettty well as expected but whenever i start a Qt or the Matrix Application the touch coordinates are interpreted the other way around, which means touch top left, the application receives bottom right etc...
My wiring ( adc channels <-> touch wiring ) has been checked accordingly and compared the schematics of a am335x evaluation module.
Please help solving this issue.

@Naseer
we should have the same hardware configuration, so could you reproduce my findings?

Best regards
Erich

PS
Interestingly the am335x evalution module seems to have an option on board for the color issue where blue and red is reversed

Hi Yordan,

Any progress from development team?

I tried different wire combinations as per Erich wiring

/* touch screen */
&tscadc {
       status = "okay";
       tsc {
                ti,wires = <4>;
                ti,x-plate-resistance = <200>;
                ti,coordinate-readouts = <5>;
                ti,wire-config = <0x00 0x11 0x22 0x33>;
                //ti,wire-config = <0x01 0x10 0x23 0x32>;                  << this one
                //ti,wire-config = <0x10 0x01 0x32 0x23>;                   << this one
       };

   };

Only two above combinations seem to give coordinates. However still not fixed.

What else can we try?

I've not received feedback. I will ping them again, but response will be most likely be delayed due to holidays in the US.

"What else can we try?"

Can you try matching/compared the dts settings with the ones for BBB LCD cape?
