This example describes how to use the controller Local Area Network (CAN) Class standard for LoopBack communication and how to set the CAN filter.
In this example, Main clock is from PLL clock and it is configured at 96MHz. The PLL clock is based on 8MHz HSE. APB1 clock is the 2 frequency division of the Main clock, APB2 clock is from Main clock.
The CAN peripheral is configured in Class communication mode.
Filter configurations of CAN peripherals are as follows:
The communication speed of CAN peripherals is 1Mbps, Filters CAN extend frames through all CAN
In order to make the program work, you must do the following :
