Thank you very much.
I will try to synchronize hardware first.

Accessing two data acquisition modules in one computer.
Currently, I am using BCI2000 software for neural recording data acquisition. The data come from USB cable. Is it possible to run two different BCI2000 softwares in one computer by connecting two USB calbes from two different hardwares. I can easily use two computers for two hardwares. However, in t...

Re: Relation between sampling rate and recording length (Mem
So the result is that it runs for some time, and then goes into suspended state? Does it always record the same amount of data, or a different amount each time? Which Signal Processing and Application modules are you using? Yes, it always record the same amount of data. However, interestingly the am...

Re: Relation between sampling rate and recording length (Mem
Thank you very much for your suggestion. I did not understand your assumption fully yet, but it seems very reasonable. I deleted postBuf because it is not necessary for this version, and tried your suggested code, buf=(BYTE *) malloc (sizeof(int) * alen); instead of buf=(BYTE *) malloc (sizeof(BYTE)...

Re: Relation between sampling rate and recording length (Mem
Thank you very much. After some period of time, recording automatically finishes without any specific error. 'Suspend' changes automatically to 'Resume' and recording stops. For BCI2000 viewer, the error message is 'External exception EEFFACE.'. I attached my data acquisition module important code. ...

Relation between sampling rate and recording length (Memory)
Previously, I have a difficulty in increasing recording time on my system. The hardware we designed has a sampling rate of 540 k sample per second (540 kSps) consisting of 36 channels. Therefore, each channel has a sampling rate of 15 kSps. When I press 'Start' button in operate module in order to r...

Re: How to increase maximum recording points?
I could not find DummyApplication Module.
Where can I get this module?
Thank you.

How to increase maximum recording points?
I am working on developing neural recording system. The hardware we designed has a sampling rate of 540 k sample per second (540 kSps) consisting of 36 channels. Therefore, each channel has a sampling rate of 15 kSps. I made a source module in order to accept the data from our hardware. It works fin...

It works! Thank you very much. How did you come up with the specific numbers, 512 and 64? By the way, the hardware I am using is the custom designed receiver. Through wireless link, neural signals are received, demodulated, and send to FPGA board. FPGA converts the demodulated analog data to digital...
