Goodix provides a custom Device Synchronization Profile (DSP) example that enables synchronization of timing sequences between devices through parameter modification on a mobile App (GRToolbox). This means that a group of devices can operate in synchronous mode under one timing source.
This document introduces how to use and verify the DSP example in a GR551x Software Development Kit (SDK).
