Can I Set a Buffer Size For My Reads and Writes Using NI-CAN?

Problem:
Can I set a buffer size for my CAN reads and writes using NI-CAN?

Solution:
If you are using the channel API, you can't set the buffer size for CAN reads because all memory management for the channel API is done by the system RAM. However, if you are using the frame API, you can configure the queue length using the "ncConfigCANObj" VI or function. See the link below for some guidelines on setting queue sizes using NI-CAN.
