UC3C Scope Meter And Filtering Application for uc3c_ek Documentation

Introduction

This is the documentation for UC3C-EK Scope Meter and Filtering demo running on the UC3C_EK development kit.

• Step 1: Connect J34 (1-2), J35 (1-2) and J38 (3-4) headers. Turn potentiometer P1 to have the arrow vertical (It is the trigger level).
• Step 2: Plug a USB cable from the USB_VC connector (J27) to one of the PC's USB ports. This provide power and USB serial communications port.
• Step 3: Load and run this application.
• Step 4: A sine wave is generated (takes part of the DAC task generation).
• Step 5: This signal is acquired (takes part of the ADC task acquisition).
• Step 6: A digital noise noise (controller by the push buttons PB0 and PB1) is then added to the signal
• Step 7: This noise is then filtered using a FIR filter in floating and fixed point format (takes part of the FILTER task).
• Step 8: All the signals are displayed on the LCD (takes part of the GUI task acquisition)
• Step 9: All the signals are sent to PC application (takes part of the REMOTE Task) Operating mode: The description and the installation of the PC application, the connection of the UC3C-EK to the PC are explained in AVR32831 application note. This application note is available on www.atmel.com.
