AD5940_BIA

This demo will use EVAL-ADICUP3029, EVAL_AD5940BIOZ and Impedance-Test board to carry out BIA measurements.

Overview

This example project is designed to carry out body impedance analysis. With the nature of body impedance measurements it is difficult to determine if the measurement is correct. Thus, a the Impedance Test board is provided with the hardware which models body impedance. I consists of a range of resistors and capacitors which can be used to model body impedance, contact impedance and electrode impedance.

Alternatively, the custom cables can be connected to the body to measure actual body impedance.

Measurement Requirements

The following is a list of items needed in order to replicate this demo.

  • Hardware
    • EVAL-ADICUP3029
    • EVAL-AD5940BIOZ
    • Z-Test Board
    • Mirco USB to USB cable
    • PC or Laptop with a USB port
    • Custom Cables (Optional)
  • Software
    • AD5940_BIA Example Project (Git Lab)
    • Serial Terminal Program, Such as Putty or RealTerm

Setting up the Hardware

  1. Set switch S2 to USB Arduino function in order to view data over UART. The UART baud rate is 230400
  2. Set S5 to Wall/USB to power the board from the USB cable
  3. Place the EVAL-AD5940BIOZ on top of the EVAL-ADICUP3029.
  4. Make sure the jumpers are correct. (TODO add details)
  5. Plug in the micro USB cable into the (P10) USB port on the EVAL-ADICUP3029, and the other end into the PC or laptop.

Obtaining the Source Code

The source code and include files for the project can be found on Git 

Add link to Git

Configuring the Software

To compile and run the example open the project in either Keil or IAR.

Outputting Data

The measurement results are sent to the PC via UART. To establish connection over UART, connect the Micro-USB cable to the PC and to the EVAL-ADICUP3029 board. A terminal program such as RealTerm or Putty is required to display the results

Following is the UART configuration. 

  Select COM Port
  Baud rate: 230400
  Data: 8 bit
  Parity: none
  Stop: 1 bit
  Flow Control: none
