I am using interrupt for touch sense TFT LCD application, where touching on LCD makes transition (on EINT pin) from high to low ( 3V to 0V ) and touch sense controller is through SPI interface to controller. TSI2046 is controller. Attached img. But initially it's 3V and after touching, instead showing 0V, it's displaying 1.76V reading on DMM. What should be probable causes for this? Please advise if someone came across same situation? Thank you in advance.
