Introduction
1.1
Purpose
This application note helps users to acquire a quick understand of the structure of TSCMCU
EVB sample project The sample project includes basic initial function of system clock,
system interrupt, TS, LEDs, timer and UART. After initialization function is completed, the
key service is served as a primary function for the implementation of the flow, that is to get
the key value, change the scan display mode, execute relative key operation based on the
current mode, and to execute some operations when mode toggle happens.

Module Drivers
This chapter provides driver function of each module used in system.
6.1
Overview
Driver functions of each module implement data get and sent from target peripherals. There
are 5 kinds of module used in this sample project, including: TS, Timer, UART, LED, BEEP
and Control Switch.
TS as input module processes data automatically and report the touch action to CPU
directly.
Timer as internal module generates time pulse to drive 4 derived software timers.
UART as bidirectional module not only sent out data to PC, but also get commands from PC
for transmission type switch.
LED, use GPIO actually, as output module controls if lighting is performed or not of LEDs.
There are several functions to implement various display effects.
BEEP as output module transmits PWM signal with certain frequency to drive of BEEP. The
frequency and beep period are programmable.
Control Switch as input GPIO controls the toggle between waterproof mode and other
modes
Note that Timer, UART and part of TS driver are implemented by interrupt service routine,
please refer to 9 Interrupt Service Routine for details.

Reading "0" Indicates that the touch pad of touch ch. n is not touched.

Reading "1" Indicates that the touch pad of touch ch. n is touched.
This sample project uses the reversed value of touch bytes as below by considering the
consistency with other keys.
touchByteL &= ~TOUCHL;
touchByteH &= ~TOUCHH;
This is the scan method of getting touch status.

Description
There is hardware beep module, which transmits a certain frequency pulse. The beep
module can be controlled by both software and TS module directly. This function is
designed to use the software control. This frequency determines the sound effect

Control Switch Driver
In jumper disconnect condition, the Control Switch relative GPIO pin value hold 1. After
shorted by jumper, the pin value changes to 0.
However, in this sample project, the short status is defined as default status. This sample
project uses the reversed value of touch bytes as below by considering the consistency with
other keys.
keyValue = ((~CTRL_PIN) << 15) | ((touchByteH << 8) & 0x7F00) | touchByteL;

Middleware
This chapter provides middle ware functions of some modules used in system.
7.1
Overview
Middleware implements several functions based on module driver. It provides buffer function
between API and driver layer. A module always has many middleware. For instance, there
are 7 functions provided for LED module.

Application Program
This chapter introduces the implementation details of application program.
8.1
Overview
Application program implements the design requirement by integration system resources.
There are 2 categories of application program in this sample project: touch key service
application and TS module register value read and send out application.
For touch key service part, provide 4 kinds of demonstrate modes named as sync mode,
function mode, hold mode and waterproof mode. Section 8.2 describes the details of this
part.
For TS register value part, there is a 14 × 40 data matrix act as data buffer. This buffer is
FIFO structure. Section 8.3 introduces this matrix.

Key Service Application
In key service application, it provides a sub system for mode toggle. The condition of mode
toggle is to touch no less than 6 keys and hold at least 2 seconds.
There are 2 concepts: active mode and load mode. Active mode means the current mode
while load mode means the oncoming mode. In normal conditions, active mode and load
mode are equivalent. However, when the mode is switched, load mode becomes the
oncoming mode, which makes it not equivalent to active mode anymore. When the next
program executes within the circle, the function switches the mode automatically once the
above-mentioned difference is captured.
There are 2 concepts in key service part too, which are the current key value and the
previous key value. In normal condition, these 2 values are equivalent. However, when
touch is occurred or released, the current key value changes. In this case, the function
switches to key service automatically in next program execution within the circle.
There are 2 derived timers used: local timer of each mode and common timer for refurbish.
Key service base function flow chart has shown as below:

Sync Mode supports multi point touch. The LED status (light or not) follows the key touch
action, and beep is directly driven by TS module. The below diagram shows the change of
LED status:

Hold Mode
In Hold Mode, beep sound is combined with 2 effects and controlled by software. For LED,
it holds light status until the same key is touched again within a short period of time, or if
there is no touch action of other keys within 3 seconds.

Waterproof Mode
It demonstrates the function of waterproof performance, for details of waterproof design
guide, please refer to MCU-AN-500141-E: TSCMCU-Waterproof_Guideline for more
information.
In waterproof mode, the APISTM mode 1 is used, that means it supports single-point touch.
The touch effect is partially similar with sync mode. It beeps when the touch is detected and
LED keeps turning ON until the touch key is released.

TS Register Value Application
Environment change is reflected in TS module register data. By getting these data, it
enhances the digital signal processing. The relative data includes: Impedance,
Cal_Impedance and Strength. Argument of TSC_GetValueUnit function points out the data
type.
