Thanks Paul for you replies.

I was working with the EX1 sensor, and I was getting the values with my own data acquisition software. I want to ask, do we need to do any calculations with the value we get to get the true value of EX1 sensor :?: except the 256 division to get the 32 bit value.

I ...

Hi
I am having quite same problem but with numbers larger than 20 some thousands.

I am getting the data for GSR with my own data acquisition program. The value that I get from the ring buffer-the original value without any multiplication- is varying from 8 digit number to 9 digit number e.g ...

Hi
Thanks Paul
Sorry, you are right. I just got used to ask all questions from you ,
Thanks a lot man

Hi Paul

I know tried also with dividing by 256, yet its not quite comparable to actiview and normal rates what I wrote there was the example I was trying at that time. I also mentioned the units are in s(siemens) not s for seconds.

Oh and about the packet number, ignore that, i was saving to the ...

Hei Paul

Thanks for helping
I have a problem with the data I get. A normal GSR value is about 20,000 s(siemens)
or 625,000 ns or 625 µs. While, I am comparing the GSR values of my Data acquisition program and actiview, I see that I get the value around 800 ns from activew!!!! I was surprised, I ...

Hi Paul

Thanks for the help. Its working, its amazing :D . I really have no idea how far could I get without ur help. I am making an API for it, so its gonna like convert or somehow translate the data. I noticed lots of stuff I didn care in my codes such as checking synch channel checking whether ...

Thanks Paul,

I did what you said, I made a loop for calling the READ_POINTER, counting to 10 and I got the following numbers.

0
0
0
262144
262144
524288
593920
742400
890880
1039360

there is a Sleep(50) in this counter which 50ms is less than the sample rate, so that is why i am getting the same ...

Thanks Paul for all helps
I am getting integers from READ_POINTER

I made a loop to call this function, but the numbers increment haphazardly. However as you said all of them are multiples of 4.

here are the few first numbers

0
262144
524288
593920
742400

So, first I wanted ...

Thanks a lot Paul.

Sorry I have to ask some more question. I read that topic, but some parts I do not understand, let me specify this.
I have an array of data: CHAR data[64]
I made a ring buffer like this: PUCHAR ringbuffer;
and I allocated memory: ringbuffer = (PUCHAR)VirtualAlloc(NULL ...

now I got the READ_POINTER to work, the output is a pointer to an integer. I dont know what is this integer. I guess we used an array of 64 zero bytes data to save the data of all sockets, if it is correct then what is the mapping of sockets to array index? and why there is only a pointer to an ...

Hi
I am a student who is new to biosemi and not expert in programming. I am designing a data acquisition program for biosemi. I can enable the handshake and communicate with the usb. but I have problem in READ_POINTER function. I do not exactly understand how to work with this function to receive ...
