The PCBUSB library realizes a CAN to USB user-space driver under macOS for PCAN-USB interfaces from PEAK-System Technik, Darmstadt. It supports up to 8 PCAN-USB or PCAN-USB FD devices.

The dynamic library libPCBUSB is running under macOS 10.13 and later (x86_64 architecture). Since version 0.10.1 it is running under macOS Big Sur (11.x) or macOS Monterey (12.x) as Universal macOS Binary.

See the MacCAN website to learn more.

This repo offers two command line tools that are build upon the PCBUSB library:

• can_moni to view incoming CAN messages
• can_test to test CAN communication

Both tools run as a standalone program, therefor it is not necessary to install the PCBUSB library to run them.

can_moni is a command line tool to view incoming CAN messages. I hate this messing around with binary masks for identifier filtering. So I wrote this little program to have an exclude list for single identifiers or identifier ranges (see program option --exclude or just -x). Precede the list with a ~ and you get an include list.

Type can_moni --help to display all program options.

can_test is a command line tool to test CAN communication. Originally developed for electronic environmental tests on an embedded Linux system with SocketCAN, I´m using it for many years as a traffic generator for CAN stress-tests.

Type can_test --help to display all program options.

• macOS 12.0 and later (Intel and Apple silicon)

• macOS Sonoma (14.5) on a Mac mini (M1, 2020)
• Apple clang version 15.0.0 (clang-1500.3.9.4)
• Xcode Version 15.4 (15F31d)

• macOS Monterey (12.7.5) on a MacBook Pro (2019)
• Apple clang version 13.0.0 (clang-1300.0.29.30)
• Xcode Version 13.2.1 (13C100)

Only the following devices from PEAK-System Technik are supported:

• PCAN-USB (product code: IPEH-002021, IPEH-002022)
• PCAN-USB FD (product code: IPEH-004022)

For a list of known bugs and caveats in the underlying PCBUSB library read the documentation of the appropriated library version.

PCAN-USB Pro FD devices are supported since version 0.10 of the PCBUSB library, but only the first channel (CAN1).

Since version 0.5.3 macOS 11 or newer is required to run the PCBUSB utilities as Universal macOS Binary.

This repo contains only binaries files of the PCBUSB utilities.
