This demo will use EVAL-ADICUP3029, EVAL_AD5940BIOZ and Impedance-Test board to carry out BIA measurements.
This example project is designed to carry out body impedance analysis (BIA) measurements. The Impedance Test board is provided with the hardware which models body impedance. It 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.
The following is a list of items required to carry out the measurement.
The source code and include files for the project can be found on Git
Add link to Git
To compile and run the example open the project in either Keil or IAR.
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
The data on the terminal consists of the Frequency of the excitation signal, the magnitude of the impedance and the phase of the impedance in degrees as in below screenshot.
