Product details
Overview
IRSLIDER2EK from Silicon Laboratories is a ready-to-run infrared touchless slider demonstration kit built around the Si1142 optical sensor and C8051F800 microcontroller. It delivers real-time left-right position estimation (X in mm), ambient light (VIS/IR) and proximity (PS1/PS2) measurements, and supports pause/swipe gesture detection using dual OSRAM SFH4056 IR emitters. It is used for rapid evaluation of touchless human interface solutions in consumer electronics.
For engineers reviewing the IRSLIDER2EK datasheet, IRSLIDER2EK pinout, IRSLIDER2EK application, or IRSLIDER2EK equivalent, this page provides verified hardware configuration, firmware capabilities, USB-based software tool integration (Performance Analysis Tool, Programmer's Toolkit, IDE), and gesture algorithm behavior confirmed in the official Si1142 IRSLIDER2EK DEMO KIT USER'S GUIDE Rev. 0.3.
Technical Context
The IRSLIDER2EK implements a fixed-function embedded system where the C8051F800 MCU executes pre-loaded firmware that sequences two IR emitters (DS1, DS2), reads raw 16-bit proximity outputs from the Si1142, computes X-position in millimeters, and drives eight blue signal LEDs accordingly. Ambient light sensing uses dual photodiodes (visible + IR channels) with auto-ranging to maintain linearity across lighting conditions.
Gesture recognition runs on-device: "Pause" is detected via sustained proximity amplitude stability over ~750 ms; "Swipe Left/Right" is determined by temporal correlation and directional slope of PS1/PS2 signal pairs. All processing-including baseline subtraction, mode switching, and coordinate estimation-is performed onboard without host CPU dependency.

FAQ
What is the primary function of the IRSLIDER2EK?
The IRSLIDER2EK is a fully assembled demonstration kit that implements a touchless infrared slider using the Si1142 sensor and C8051F800 MCU. It detects hand position above the board (X in mm), recognizes pause and swipe gestures, and illuminates corresponding LEDs - all without physical contact. The IRSLIDER2EK enables immediate hands-on evaluation of Silicon Labs' optical sensing stack before custom hardware design.
Does the IRSLIDER2EK require additional hardware to operate?
No - the IRSLIDER2EK operates standalone when connected to a PC via the included USB cable. Power, communication, and firmware execution are self-contained: the USB interface powers the board (5 VIN), provides I²C-over-USB connectivity for software tools, and allows in-system programming of the C8051F800. No external sensors, power supplies, or debug probes are needed for basic slider or gesture evaluation.
Which software tools are compatible with the IRSLIDER2EK?
The IRSLIDER2EK is natively supported by three Silicon Labs software tools: the Si114x Performance Analysis Tool (for real-time graphical visualization of proximity, ambient light, and gesture events), the Si114x Programmer's Toolkit API (for PC-based C development with I²C emulation), and the Silicon Labs IDE (for full C8051F800 firmware development, debugging, and HEX image download). These tools cannot run simultaneously - only one may connect to the IRSLIDER2EK at a time.
How does the IRSLIDER2EK compute hand position?
The IRSLIDER2EK firmware activates each of the two OSRAM SFH4056 IR emitters (DS1 and DS2) sequentially, reads the corresponding 16-bit proximity values (PS1 and PS2) from the Si1142, and calculates a normalized X-coordinate in millimeters using a calibrated linear interpolation model. This position value directly maps to one of eight blue LEDs, providing visual feedback without host-side computation - the entire algorithm runs onboard the IRSLIDER2EK.
Is the IRSLIDER2EK suitable for new designs?
No - the IRSLIDER2EK is explicitly marked "Not Recommended for New Designs" in its official documentation (Rev. 0.3). It remains fully functional for evaluation and learning, but Silicon Labs intends it as a legacy reference platform. For new projects, designers should consult current-generation optical sensor kits such as those based on the Si117x or Si130x families, which offer enhanced performance, updated firmware, and active lifecycle support. The IRSLIDER2EK is retained for backward compatibility and educational use.
