There is a possibility of the trouble of the contact of the relay connector (plat 8pin-8-wire female dip converter)
that connects the touch panel. Please open JP3, 4, 5, and 6 on the evaluation board, measure panel seat resistance
(XP-XN, YP-YN), and check the resistance. Generally, the panel seat resistance is hundreds of Ω. There is a
possibility that the touch panel is not correctly connected if the resistance is over thousands of kΩ. Please
connect the relay connector and check the resistance value again.
