That means, CANUSB can work with just the FTDI USB drivers. In a next (optional) step the CANUSB DLL can be installed or the VCP mode of the FTDI chip can be enabled. The USB driver for the FTDI interface chip (as contained in the adapter) must be installed first and it is usually installed automatically by Windows when plugging in the CANUSB (for old CANUSB units produced before 2015 please see below for special instructions). You as a developer of your own software/application can choose which level/path you want. You as an end user need to find out which drivers to install if you use a software made by a 3rd party developer, check with them for more information. Also remember, if you only need one ID or one group of IDs, set both masks to the same, so the unwanted CAN frames do not slip through the second filter!ĬAN Acceptence Filter for 11bit IDs using Dual Filter ModeĬAN Acceptence Filter for 29bit ID’s using Dual Filter Modeīelow is a block diagram showing drivers you need to install to get CANUSB to work properly (some are optional) in Windows. When using 11 bit IDs this means it is possible to accept only one ID, but when using 29 bit IDs it is not possible to mask the whole ID.
When using dual filter mode, it is possible to set two regions of CAN IDs. We have prepared two documents to show how to set these filters for both 11 bit IDs and 29 bit IDs. For more information on how acceptance filters work please refer to the SJA1000 data sheet pages 44-48 and SJA1000 application note pages 19-22 (AN97076).ĬANUSB uses dual filter mode (single filter mode is not availible).
For a description of the two available modes please refer to the sections below.ĬANUSB User Manual How to use Acceptance FiltersĬANUSB uses the SJA1000 CAN controller. The CANUSB User Manual linked in below describes the adapter and the ASCII protocol which can be used to access the device in serial mode.
