If CAN receive buffer is'nt cleared before a new message arrives,will it over-write the earlier data?

Akshay Immanuel over 10 years ago

I am writing an application where a number of devices send messages to a common CAN processor in LPC1778 via CAN bus.

FYI-i dont need to use Acceptance Filter because all messages have to be allowed.

My question is that,if Device A sends a message and after Device A finishes sending a frame of data,if Device B sends a data frame,if i have not yet released the receive buffer in CAN in LPC1778,will it over-write the data or will it retry automatically when the receive buffer is released.
