How to read multiple parameters via XCP?

Hello Community,

I am developing a App Designer app for XCP commuication. I need a function which reads all parameters which are defined in the A2L (or separate list) at one. Because "value = readCharacteristic(chanObj,characteristic)" reads only one value. A loop with this function is very slow. Anybody an idea ? Or @Mathworks would you enhance this function?

Hello Walter,

I understand that you intend to read all the parameter which are defined in A2L list at once. You can first import the A2L file and then utilize a dynamic DAQ list to efficiently read multiple items simultaneously, rather than accessing them individually.

You may refer to this documentation to know about A2L files:

Please refer to this documentation for information on how to read XCP measurements with dynamic DAQ lists:

Hope this helps!
