analog inputs on the NI SPEEDY 33

[davedavidson]

I am working on the DSP module NI speedy 33. I would like to know if the analog inputs can be used to connect a rotative button which can give an analog signal, and then

be used in the VI. Maybe it sounds like a silly question, but when i read some documentations, in the analog inputs paragraph, they always mention only  that you can, through analog input,

connect some daughter modules, that's it. So, i am a bit confused about it. Anybody can help me on it ?

Hi Dave,

Really good question.  I am currently working on beefing up the documentation for the SPEEDY-33.  The Daughter Module is a separate board (eyeballing it is about 3 inchesx 1.5 inches) that increases the functionality of the SPEEDY-33.  The Daughter Module plugs into the 20-pin expansion header and the standard analog expansion I/O connectors.  On the Daughter Module it has 4 Drive Motor Outputs, 4 servo motor outputs, 4 analog  controller inputs, and an external power supply connector. 

Its main purpose is robotics applications.  I personally have used the daughter module to hook up bump sensors (could be digital, but the analog was more interesting).

Hi. About the 10bit (J4) and 20bit (J6) connectors of the Speedy-33 (the standard expansion analog I/O connectors). I need to use more analog ports that just the stereo jacks that comes with the Speedy-33. The manual says that J4 and J6 connector are analog ones but the LapView 7.1 doesn't have a way to accessing them or is there??? LapView has one 2 analog ports but those are bound to the stero jacks. Mainly, can I use the J4 and J6 analog ports with LapView 7.1 Embedded Ed. without the daughter module? How do I access them from LapView 7.1 Embedded Ed?

Thanks a lot.

Reading from the manual found here http://www.ni.com/pdf/manuals/371577b.pdf, on page 21 of 43 it talks about the J4 and J6.

"A set of two connectors, J4 and J6, make up the standard expansion analog I/O connectors, that can be used for optional daughter modules. The daughter modules can be used for applications requiring different A/D and/or D/A functionality than that provided by the standard 16-bit stereo CODEC normally found on the NI SPEEDY-33."

That makes me think that using bare J4 or J6 is not possible.  Anyone else ever find a way around this?

Hello friends,
          I am working on a project on NI Speedy 33 Module,  I need the pin configurations of the analog expansion slot provided ,  Is there any possibility to obtain it ...?   and i would also like to have details regarding the labview version that supports this dsp module.  I have installed all the components but still i dont get even the basic components which people have used on the net for describing things in their examples.  can anyone help me in this regard ..?

Hi. I work the Speedy-33 with Lapview 7.1 Embedded Edition. Have in mind that you have to tell Lapview which target you intend to use, either the speedy or the PC (among others). You can select the target in the Tools > Change current target menu (if my memory serves me).
If you manage to obtain the configuration for the analog pins of the expansion ports, please let me know.
Regards.
