The EV-Kit consists of 3 parts, the driver board, the touch demo board and the snap demo board. The quick start guide is also included. To visualise raw data from the EV-Kit, the driver board can be interfaced to any personal computer with USB support, and IQS360 software Graphical User Interface (GUI). The purpose of the IQS360EV02 EV-Kit is to help application and development engineers in evaluating the IQS360s 12 channel projected-capacitive proximity and touch sensors. A picture of the evaluation kit is shown below. Figure 1.1 CT210 (sold separately) (left), Driver board (middle left), Touch Demo board (middle right) and Snap Demo board (right) This user guide will help a user to fully use and understand the technology in this evaluation kit. The driver board will be described, followed by the touch demo board and the snap demo board. This will be shown in conjunction with an IQS360 GUI (Graphical User Interface) to simplify explanations. 2 Driver Board and IQS360 IC The IQS360 IC (Integrated Circuit) is located on the driver board. The IQS360 can be used in projected capacitive mode with up to 12 channels. The IQS360 has a configurable PWM controller which is used to drive LEDs and can be used as a general output pin. Figure 2.1 and Figure 2.2 shows the working of the PWM controller. Figure 2.1 shows the switched on LEDs on the driver board. This is achieved by running the IQS360 GUI through following the next steps. Run IQS360 Application Read and Close the Hints & Tips menu Click the Start button Click the Touch/Snap Demo icon in the demos tab. Set the Mode to Const (Constant) and CMP (Compare) value to 31. Click the Send button. The LEDs on the connection board should turn on as shown below.
