HOW TO USE
1. Connection of connector pin.
Solder attached connector pin (8pin) at the
position pictured in Figure 3.
2. Connect the LC717A10ARGPEVB to a board
with a designed switch pattern. When designing
a switch pattern, please refer to the Application
and Design Note on the
ON Semiconductor Touch
Sensor Homepage
.
3. Connect LC717A10ARGPGEVB to PC through
an USB-to-Serial conversion module. Supply the
power, and verify the Power LED is turned on.
4. Install evaluation software to PC. The evaluation
software is available from the ON Semiconductor
Homepage , and selecting “LC717A10 software”.
Double-click on the icon “LC717A10App.exe”
from the installed folder and start it.
5. Press RESET Switch when evaluation board is
acting strange.
6. Please note: If the user directly touches the LSI on
the evaluation board or patterns with their finger, it
may cause malfunction or breakdown.
