3 TSC Demo Functions
This chapter introduces TSC demo system usage and functions.
3.1 Demo System Build-up
Program TSC demo code “TSC_LPC_1V0” on MB95200 EV-board and set this EV-board
into “normal run” mode. Then connect EV-board and TSC demo through IDC10 cable.

3.3 Demo System Power-on
Provide power to EV-board will power on the whole TSC demo system. MB95200 EV-board
supports the below 3 power provided method.
4-pcs batteries
9V DC power supplier
USB cable
After power on, LED5 on EV-board is light to indicate power-on status and LED2 on EV-
board winks to indicate TSC demo code running.

3.4 APIS (Adjacent Pattern Interference Suppression) Modes
This demo system can support the three kinds of APIS mode.
APIS mode I: reports the strongest output only.
APIS mode II: reports all outputs to overcome the value of Strength Threshold Register
APIS mode III: reports two strongest outputs for multi-touch application

3.6 Waterproof Key Pad
The system demonstrates waterproof capability of key pad of ATA2508. The below picture is
the reference. If water is dropped on the key pad, ATA 2508 still can work normally and do
the correct key-value detection.
Refer to “ATA2508 Users Manual V1.4 (EN) v01” for the detailed characteristic.

4.2 Tuning System Build-up
Connect DCC DP17 tuning kit and TSC demo board through the special IDC10 cable. Then
connect the kit into PC though USB cable.
In the way, TSC ATA2508 parameter can be tuned and tied on PC software GUI.
Refer to “ATA2508 Users Manual V1.4 (EN) v01” for the detailed tuning method.

Chapter 5 Demo Firmware
5 Demo Firmware
This chapter introduces TSC pad and IC tuning interface and method.
In this solution, TSC ATA2508 is controlled by MCU through I2C. If MCU hasn’t I2C
peripheral just like MB95F204K, I2C communication can be simulated by general IO port. In
this case, Config.h on demo F/W “TSC_LPC_1V0” will be re-defined to realize the S/W I2C.
At the same time, MCU only controls buzzer simply according to four key values. If the
different solution is requested, user can modify MCU application code in Main.c file of demo
F/W project.
