EB076 Touchscreen not working

[technobit]

Does anybody here have experience with the touchscreen of the EB076 board? I get nothing back from the touchscreen, even the testfiles do not work. the display works fine, also the card reader.

Hi

Heres a link to one of my programs using the touch screen

Try this one see if you can get going. You dont need the motor board to actually test the touch operation.

Also try this one

Thank you for help. It seems that the touchscreen is not working.... I bought it 3 weeks ago and it never worked, so this must be under warranty. Now I have to wait for a new one.

Hi
I recommend you pm Benj at Matrix for advice.

Hello
I've done some work with the EB076 touchscreen and I have seen some with faulty touchscreens. They either send the same touch coordinates regardless where you touch or they send nothing. Do you have the USB programming cable so you can run the 4D configuration software for the display?

If you run the software that you will find on the 4D website or on the Tigal site, it will give you a lot more info about what the display is doing and you can also test and calibrate the touch screen.

Hello,

Have you tried the test routine?

Do you have the 16F877A chip to test it on?

[technobit]

This test routine doesn´t work on my system.

Here the error messages:
EB076.c: 965 : error: Unknown or missing component: Custom20.EnableTouchscreenPicaso
EB076.c: 974 : error: Unknown or missing component: Custom20.GetTouchCoordinatesPicaso
EB076.c: 983 : error: Unknown or missing component: Custom20.ReadTouchCoordinatesPicaso
EB076.c: 987 : error: Unknown or missing component: Custom20.ReadTouchCoordinatesPicaso
EB076.c: 991 : error: Unknown or missing component: Custom20.DrawCircle

Now I have the situation that I need very quick a working hard- and software environment for my further projects, my boss is already getting angry, because he thinks I made the wrong decicion to develope with flowcode.....

Hello,

The test routine has been rewritten could you try the one from here:

It is the 16F877A not the 16F887A < this was a typo sorry.

[technobit]

Hello,

I tried (of course with 16F877A). The LEDs are blinking and display changed to yellow, but it doesn´t show any reaction when touching the screen.

Hi Technobit,

Can you please confirm that you are using the latest release of Flowcode PIC which is v5.4? I believe I remember finding a bug which was fixed for this release.

If the display is turning yellow then the PIC is correctly initialising the display and telling it to clear itself with the background colour. This means your connections and baud should all be ok. You can prove this by altering the background colour in the gLCD component properties and testing to make sure the hardware does the same.

I have 5.4.00, Release 03.08.2012
