TDMS Library

Library for generating TDMS file format.

Library Features

• Support for Little-Endian systems
• Support for integer, float, double, Boolean and string raw data
• Converting normal time and date to NI LabVIEW format

How To Use

1. Add library files to your project.
2. Config TDMS_config.h.
3. Define File, Channel Group and Channel object structures. For example:

TDMS_File_t  FileTDMS;
TDMS_Group_t  Group1;
TDMS_Channel_t  Channel1Group1;

4. Create File, Channel Group and Channel objects. For example:

if (TDMS_InitFile(&FileTDMS) != TDMS_OK)
    printf("Create file failed!");

if (TDMS_AddGroupToFile(&Group1,
                        &FileTDMS,
                        "Group 1 name") != TDMS_OK)
    printf("Add Group failed!");

if (TDMS_AddChannelToGroup(&Channel1Group1,
                           &Group1,
                           "Channel 1 name",
                           TDMS_DataType_U8) != TDMS_OK)
    printf("Add Channel 1 failed!");

5. Generate first part of file with TDMS_GenFirstPart and save the out buffer on disk.
6. Add properties to File, Channel Group or Channel with TDMS_AddPropertyToFile, TDMS_AddPropertyToGroup or TDMS_AddPropertyToChannel then save the out buffer on disk.
7. Add data to Channels with TDMS_SetChannelDataValues or add data to all Channels of a Channel Group with TDMS_SetGroupDataValues then save the out buffer on disk.

Example

To run the basic example, follow these steps:

1. Clone the repository

git clone https://github.com/MahdaSystem/TDMS.git

2. Go to the example directory

cd ./TDMS/example/basic

3. Run the make command

make all

4. Run the example

./build/output.elf

5. The .tdms file will be generated in the build directory
