Simple CAN-logger with user-space driver using IOKitLib and IOUSBLib for PEAK PCAN-USB Adapters. The driver is based on the USBPrivateDataSample and the pcan linux driver.
You can simply paste numbers into the log window, which will be translated into can-frames and sent over the bus. This has been tested with plain text, formatted text and Numbers spreadsheets.
For example:
0x80000005 0xc0 0xff 0xee;
will send an CAN2.0B frame with identfier 5 and the trailing numbers as payload bytes. The frame-length will be automatically set to 3.
You can paste multiple messages at once, just paste multiple rows (Numbers) or lines separated by newline and/or semicolon. For example:
0x5 0xc0 0xff 0xee;
0x13 0xba 0xbe;
will generate two CAN2.0A messages, the first with three byte payload, the second with two byte.
You can send frames with CAN2.0B extended identifier by OR-ing a number respresenting the 29-bit identifier with 0x80000000. For example:
0x80000005 0xc0 0xff 0xee;
will send a CAN2.0B frame with id 5 and three bytes payload.
You can also paste RTR-frames by OR-ing the id you expect to answer with 0x40000000. RTR-frames should have a length field set stating the length of data you expect to receive. You can do this by appending dummy numbers (e.g. zeroes). For example:
0x40000006 0 0
will send a RTR-frame to id 6 expecting two bytes in return.
Both flags can be combined by OR-ing with 0xC0000000
- Get rid of too many global variables in the driver part
- Export logs
- Maybe some script interface
