Hello AAG,

Did you answer your own question?  You marked your reply as the solution rather than Christian's.  Yet it still sounds like you have more questions.

Also, please use full words in your message such as "Can you please" rather than "Can u pls".  You don't need to "text message" here.  Use your entire keyboard.

Are you the same person as Memy in this thread?

No need to wait for the future. You can do it by clicking on the "options" menu on the top right corner of that post and select unmark. 🙂

Hi,

This link doesn't tell what are these frame and channel API....

Hai,

Visit the link www.renesasinteractive.com that gives a guided tour on CAN.

Channel API is nothing but higher level of vi's for all users.  For using these API's you need *.dbc or *.ncd file.  These API's are like High level vi's in DAQ.

Frame API or lower level vi's for advanced users but all the functionalities that channel API does can be acheived through Frame API.  When Frame API is involved you will be directly dealing with can frames where as Channel API is bit more sophisticated.  It uses the input file (*.dbc or *.ncd) -> acquires the frames-> scales the can data bits with respect to scaling information in the dbc file and gives the output directly
