Programmable LED Panel

The Programmable LED Panel Board is a simple 10x14 LED matrix panel. The individual LEDs from the matrix can be controlled either with a Raspberry Pi RP2040 MCU or a Lattice ICE40UP5K FPGA. The LED sequences displayed by the matrix can be synchronized with an external triggering signal. The LED Panel Board can then be used for measuring latency in vision systems. The custom patterns displayed by the LED Panel Board can also be used for training and evaluation of extended reality systems (XR goggles, mobile robots and any other device that uses machine vision for environment mapping).

Video Latency Testing Probe

The Video Latency Testing Probe is a small-sized probe that can be used for performing latency testing in video systems that combine cameras, displays and light sources. The probe includes two light-sensing elements and an accelerometer combined with an RP2040 MCU. The MCU can be programmed with firmware that reacts to the light pulses detected by the light-sensing elements, measures the time elapsed between pulses, collects the readouts and passes them to the PC or drives triggering signals for external equipment. By combining the IMU readouts, the probe can be used on a platform that moves with respect to the light sources. The mechanical outline for the probe has been optimized so that the probe can also be installed in extended reality (XR) glasses for measuring the XR display latency responses.
