„ Evaluation mode


Applicable Evaluation Mode
(1) Touch-position and touch-pressure measurement.
(2) Keypad scan function.
(3) GPIO control function.
(4) LED dimmer control function.
(1) Touch-position and touch-pressure measurement.



In case of evaluating a Touch Screen function of the AK4184A, it is necessary to connect the Touch Panel with
J1 terminal as shown Table 1. Regarding pin assignment of J1, refer to Table 1 or circuit diagram in this
manual. As for the AK4184A’s register definitions, refer to datasheet of the AK4184A.
4-wire resistive touch screen should be connected to J1.
The pin assignment of J1 is shown on Table 2.
