MSS Components Used
 ARM® Cortex™-M3 processor
 Clock conditioning circuitry (CCC)
 General purpose input/output (GPIO)
 UART_0
 Analog compute engine (ACE)
Target Board
SmartFusion 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 SmartFusion analog channels and ACE that is
used to monitor the voltage across the potentiometer (POT). The UART is used to send the analog-to-digital
converter (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 for SmartFusion cSoC.
 Configure the SmartFusion cSoC peripherals.
 Generate the SmartFusion cSoC MSS component.
 Perform synthesis and layout, and generate a programming file to program the SmartFusion cSoC device.
 Program the SmartFusion A2F200M3F or A2F500M3F cSoC device.
 Open the software project in µVision®4 IDE and write the application program.
 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 the voltage across a POT and four flags are included for the voltage monitoring. These
flags are used to drive the four LEDs on the board.
