In OpenVibe, it looks like you need to interpret the triggers manually. From the V-Amp driver manual:
Has anyone written a box or script that will interpret the level of the V-Amp trigger channel and output stimulations?The V-Amp driver for OpenViBE outputs the status of the trigger line on a dedicated channel. This value is a 32 bit integer: digital inputs (bits 0 - 8) + output (bit 9) state (+ 22 reserved bit). This channel is thus a square signal with different levels, deducing the trigger bit values is then up to the box or script that reads this channel.
For example, receiving on the trigger channel the value 231:
231 = 27 + 26 + 25 + 22 + 2 + 1 231 = 1110 0111 b
The code 231 tells you that the input trigger at index 0, 1, 2, 5, 6, and 7 are activated. The input triggers 3 and 4 are off.
Any suggestions about how to do it would also be helpful. I'm new to OpenVibe. Thanks!
