Introduction

We continuously contribute to the OpenVibe's Acquisition server. We add additional features and bug fixes. Recently all of them had been integrated in the mainstream version of OpenVibe.

Improvements

• Software Tagging - for more information check here
• An improved driver for Gtec's g.USBamp amplifier which does not lose data chunks compared to the original version provided by OpenVibe. Our driver was developed by guidelines from G.TEC. Threading, asynchronous IO, process priority elevation and a ring buffer were added to improve the data acquisition. This version also supports multiple devices acquiring data synchronously. The different data streams do not shift with time when sync cables are used with this driver. There is no drift, but the data streams can be shifted according to G.TEC with +/-1 sample (not every time). We have a scenario that detects if there is a shift between the data streams coming from the amplifiers
• Fieldtrip driver - memory leak fix [123]
• Numerous other bug fixes
