1 Introduction
This manual explains how to use the AS8579-TS_EK_DB hardware in combination with the included
software GUI. Both (HW & SW) are designed to test and evaluate the features of AS8579 capacitive
sensor. The AS8579 is a sensor, which measures the capacitive value by separately measuring the
10-bit Information (accumulated to 14-bit) of I and Q. This 14-bit information provides the capacitance
of the application. The I and Q data can be read over an SPI interface.

2.2 How to Start
Please use the following instructions to get the Demoboard and software running:
1. Open AS8579-TS_EK_DB user manual and read instructions carefully (from USB Stick)
2. Run AS5xxx_EvalSW_USB-I&P-Box_v1-6-0.exe on your PC to install the software (from USB
Stick)
3. Connect USB I&P Box with AS8579 Demoboard
4. Check if Jumper is set to ONBoardCLK (see Figure 3:
Jumper Setting OnBoardCLK)
5. Connect the desired SEN lines of AS8579 Demoboard (use header or test pins) to your
measurement circuit
6. Connect USB I&P Box with PC via Micro USB cable
7. Run USB I&P Box software on your PC and select AS8579 from dropdown menu
8. Select the right SEN line and start testing and evaluating.
