To read and write CAN data, you must install the USB CAN Peak device driver. Embed supports CAN Peak device drivers v4.4 and higher. The driver can be downloaded from https://phytools.com/products/pcan-view-free-can-software.
You can connect a PCAN USB-CAN device (purchased separately) to a block diagram using CAN PEAK read and CAN PEAK write blocks. These blocks let you easily log or plot data, or run a virtual plant or controller for offline tuning.
To read or write CAN data
1. Plug in the USB-CAN device.
2. Under Blocks > Real Time, wire CAN PEAK Read and/or CAN PEAK Write blocks into a diagram.
You can transmit and receive data from any number of bus IDs in a single diagram. The CAN PEAK Read and CAN PEAK Write blocks let you read data from and write data to a CAN bus. Baud rate, data types and byte offset within the data packet can be quickly modified through the dialogs for these blocks. Embed supports bus speeds of 1 MHZ, 500 kHz, and 250 kHz.
Embed interfaces with CAN devices that can be connected to any CAN bus. Using Embed, you can exchange data between Embed and a CAN device using the CAN PEAK Read and CAN PEAK Write blocks.
