1Introduction
This document introduces software environment and development recommendations for the ABOV 8-
bit Touch/LED-Driver MCU starter kit. It offers an easy way to develop the Home Appliance Touch.
1. The starter kit board contains a debugger called “OCD”, which eliminates the need for
additional devices for MCU programming and debugging.
2. In this Quick Start Guide, we’ll discuss how to operate A96T418GDN Shield Board, as an
example, step by step

3.1 Prepare the Starter kit & Shield Board
Hardware components of the Starter Kit
1. The starter kit board is comprised of a device board and an OCD board. The two boards can
be separated if necessary.
2. Device board configuration
A. ABOV 8-bit MCU
B. Pin Headers connected to MCU
C. LED, switch and jumper to check input/output, reset, and debugger pins
3. OCD board configuration
A. OCD for programming and debugging with ABOV 8-bit MCU(connected to USB port of
PC)
B. Supports OCD Disconnection Mode (In this mode, OCD DSCL and DSDA port can be
used as UART TX and UART RX, respectively)

3.3 Connect the Starter Kit to your PC
PC connection via USB on the Starter Kit
Connect the USB 2.0 (micro-B type) cable to the Starter Kit as shown in Figure 10.
1. If the PC is properly connected, the USB Power LED will be turned on. -①
2. If the power switch is moved in the direction shown below, the OCD detects the IC (A96T418)
and the LED is turned on. -②

1. #define LED_DRV_EN X
: If you are using lib_leddriver.LIB, set X=1, otherwise set X=0.
2. #define DBG_MSG_EN X
: If you are using lib_debug.LIB, set X=1, otherwise set X=0.
3. #define TS_LED_TIME_DIV 1
: Touch operation is performed during the stable VDD section (LED-OFF section). Therefore
touch data variation is relatively small, LED brightness is relatively dark.
