IQ Switch ProxSense Series IQS572EV02 Arduino Shield Module Datasheet Trackpad Arduino Shield PCB using IQS572 1 Overview The IQS572-B000 is a trackpad solution including on-chip gesture recognition, flexible device setup and leading sensitivity management and adjustment. The IQS572EV02 uses an 8x8 diamond sensor pattern to detect user proximity and touch, identify finger position co-ordinates, and generate gesture outputs based on the finger interaction. With effective on-chip sensor co-ordinate filtering, and advanced processing algorithms, the IQS572 provides reliable and stable operational outputs. 2 The sensor reports these outputs via standard I C protocol to the master (in this case the Arduino), and is also fully configurable and programmable via this interface. The IQS572-B000 is a standard IQS5xx-B000 product, and thus the complete IQS5xx-B000 product datasheet can be referenced for all IQS572-B000 trackpad information: Figure 1.1 IQS572EV02 IQ Switch ProxSense Series ATI C (TP) 2 ATI C (ALP) 18 Active Mode report 13 Idle Touch report rate 50 rate Idle Mode report 75 LP1 report rate 60 rate LP2 report rate 120 - - Active Mode timeout 5 Idle Touch timeout 60 Idle Mode timeout 45 LP1 timeout 30 Total multi-touches 5 X & Y resolution 1024 To obtain the full device configuration, simply connect the trackpad module to a CT210 (or DS100), and run it with the IQS5xx-B000 PC GUI software. At start up all GUI parameters are updated to match the on-chip values, and can therefore easily be read in the GUI. 3 Connecting to PC Although the module is designed to be used as a plug-in shield PCB for the Arduino Uno, it can also be connected to the Azoteq PC software for evaluation, visualisation, configuration and programming. 3.1 Hardware connections To connect the IQS572EV02 to the PC, the following needs to be linked between the CT210/DS100 and the module.
