TDM Header Writer C API: Newer version available?

[Henrik82]

Hello support team,

we are using in our software the library "nilibddc.dll" for importing TDM data. The library "niTdmHW1_0.dll" is used to export data into the TDM data format. Now, our requirement is to support text channels. The library "niTdmHW1_0.dll" does not support the "STRING" data type but various numeric data types and cyclic channels (implicit). On the other hand, the library "nilibddc.dll" supports the data type "STRING" but only a few numeric data types (UINT8, INT16, INT32, FLOAT and DOUBLE).

Our export must support the following data types:

• INT8
• INT16
• INT32
• INT64
• UINT8
• UINT16
• UINT32
• UINT64
• FLOAT
• DOUBLE
• STRING
• Impilict channel

What is the best way to solve our problem? Maybe, it exists a newer version of the library "niTdmHW1_0.dll" which supports creating text channels?!

Thank you very much for your help.

Best regards,

Henrik

Hi Henrik,

can you please explain a bit what kind of text channel you envision to use:

1. General purpose text channel
   Each value of the text channel can be different (random)
2. Assignment / enumeration (text) channel
   The possible channel values are limited and aligned with a numeric (channel) value

What kind of string channels do you want to add?

Are they really free or more like enumerations.

[Henrik82]

No, the values are not limited. The value count is free and each value of the channel can differ. The character count can be either fixed or non fixed.

For example:

0s -> "Test1"

1,5s -> "Test2"

5s -> "Hello"

...

The text channel should be some kind of a marker channel (event-oriented).  Its appropriate time channel is not cyclic.

Does anybody have any suggestions about this issue?

I would really appreciate an answer.

Thanks for your help!!!
