MSS Components Used
 ARM® Cortex™-M3 processor
 Clock conditioning circuitry (CCC)
 General purpose input/output (GPIO)
 UART_0
 ACE
Target Board
Smart Fusion Evaluation Kit Board (A2F-EVAL-KIT) or SmartFusion Development Kit Board (A2F-DEV-KIT).
Objective
The objective of this tutorial is to instruct how to configure the SmartFusion analog channels and ACE, used
to monitor the voltage across the potentiometer. The UART is used to send the ADC results to a terminal
program.
Design Steps
Following are the major steps to be executed for this tutorial:
 Create a Libero SoC v10.0 project and use the SmartFusion cSoC MSS configurator to configure ACE,
adding a voltage monitor with flags.
 Generate the SmartFusion cSoC MSS component.
 Perform synthesis and layout, and generate a programming file to program the SmartFusion cSoC device.
 Program the SmartFusionA2F200M3F or A2F500M3F cSoC device.
 Open the software project in IAR Embedded Workbench IDE and write application code.
Run an application to monitor the voltage across the POT on the SmartFusion Evaluation Kit Board or
Development Kit Board.
The hardware configuration has four flags:
 Over 1.0 V
 Over 1.5 V
 Over 2.0 V
 Over 2.5 V
The design monitors voltage across a potentiometer (POT) and the four flags are included for the voltage
monitoring. These flags are used to drive the four LEDs on the board.

Step 7 - Configuring the Serial Terminal Emulation Program
Prior to running the application program, you need to configure the terminal emulator program
(HyperTerminal, included with Windows®) on your PC. Perform the following steps to use the SmartFusion
Evaluation Kit Board or the SmartFusion Development Kit Board:
1.
Connect a second mini USB cable between the USB connector on the SmartFusion Evaluation Kit
Board or the SmartFusion Development Kit Board and a USB port of your computer. If Windows
prompts you to connect to Windows Update, select No, not at this time and click Next.
2.
If the SFE USB to RS232 Controller drivers are automatically detected (this can be verified in Device
Manager), as shown in Figure 43 · , proceed to next step; otherwise follow the Step 8 - Installing Drivers
for the USB to RS232 Bridge.

Use the following steps to install drivers for the USB to RS232 Bridge:
1.
Unzip the USB_Drivers.zip file and browse to the USB Drivers folder. Refer to the instructions in the
readme.txt file contained in the zip file.
2.
Double click (run) PreInstaller.exe.
3.
Accept the default installation location and click Install.
4.
Click Continue Anyway if prompted.
5.
When the installation is complete, click OK. The Ports (COM & LPT) section of the Device Manager lists
SFE USB to RS232 Controller under the Ports section of the Device Manager.
Step 9 - Debugging the Application Project Using IAR
Follow the steps given below to debug the application project using IAR:
1.
