Bit Rate Calculation Tool

Calculation of Register Values for CAN and CAN FD Bit Rates

Description

The Bit Rate Calculation Tool determines the register values of the CAN controller for the desired CAN and CAN FD bit rates.

Various parameters such as clock frequencies and sample points can be selected to further narrow down the list of results. An optional tolerance of up to 5 % can be defined to include nearby results in the evaluation. The bit timing values contained in the results (BRP, TSEG1, TSEG2, and SJW) can be stored and loaded for viewing across platforms. In the Android and iOS versions, it is also possible to forward the results directly from the app via e-mail. Furthermore, in the Windows application, individual lines can be copied from the result list to the clipboard to use their bitrate values in the PCAN-Basic API and applications based on it.

The transmission rate calculation supports engineers in planning and optimizing classical CAN and modern CAN FD networks. The Bit Rate Calculation Tool is available free of charge for Android, iOS, and Windows.
