We are using Colibri VF50/VF61, Iris carrier board, oe-core with qt application and 7 inch display with resistive touch panel. We have got the display part (18-bit interface) working but the resistive touch panel does not detect touch signal. We have crosschecked the connections. Also we are getting the analog signals changing on X19 connector on Iris board when screen is touched.
We tried calling ts_calibrate to calibrate the touch screen but the touch is not detected on any part of screen. We tried ts_test, ts_print_raw but no output is received on command line.
We tried replacing the touch panel but no response on screen only analog signals are observed on scope. We have tested the touch panel on other system and found to be working.
Is there any way or command to check the adc count for the touch signals.
Please suggest solution to make touch panel work.
