# CAN Pre-Installation Requirements

Before using FLIP to perform ISP operations through a CAN dongle, you must install the dongle driver. The driver installation procedure is described in the documentation of the dongle.

But this is not sufficient; FLIP cannot interface directly with a dongle driver; it requires a library of functions provided by the manufacturer of the dongle and called the Application Programming Interface (API).

These API libraries are now part of the FLIP package.

The following table gives the names of the API DLLs for the CAN dongles supported by FLIP.

Manufacturer | IXXAT | PEAK | RM | SYSTEC | VECTOR
DLL Name | vci11un6.dll | canapi2.dll | atrs232.dll * | usbcan32.dll | vcand32.dll

* The atrs232.dll file is an Atmel's API written for the RS232 port.
