AKD4160-A Datasheet, PDF (4/37 Pages) Asahi Kasei Microsystems – Evaluation board Rev.0 for AK4160

[AKD4160-A]
■ Evaluation mode
When evaluating the functions of the AK4160, it is necessary to connect a touch pad board with the PORT4.
Regarding pin assignment of PORT4, refer to Figure 4 or circuit diagrams in this manual. As for the
AK4160’s register definitions, refer to the datasheet of the AK4160.
(1) 16-channel Touch Switch <Default>
Capacitive touch sensors up to 16 channels are available for touch switch.
Connect the touch pad board “16PAD” with the PORT4.
Set up the registers of AK4160 with the “akd4160-a.exe” by loading the register file “ak4160_16ch Touch
Switch.akr” which is included in the CD. (Refer to Page 8)
(2) 8-channel Touch Switch and 8-channel LED Display
Maximum 8 channels out of the 16-channel capacitive touch sensors can be configured to LED drives.
GPIOn (n=0ʙ7) outputs the status of terminal CSn. (Table 2)
Connect the touch pad board “8PAD+8LED” with the PORT4.
Set up the registers of AK4160 with the “akd4160-a.exe” by loading the register file “ak4160_8ch Touch Switch
& 8ch LED Display.akr” which is included in the CD. (Refer to Page 8)
