4.3 Specific Requirements

4.3.1 Device Driver Functionality

The AdsCAN.dll driver needs to decide which driver should be called

depending on different hardware.

The AdsCAN.dll driver should properly translate the function parameters

to a lower layer driver.

4.3.2 The CAN Driver Framework

All user-mode functionality is implemented through Win32 communica-

tion API Functions.

The AdsCan.dll unified driver interface for all CAN cards is shown in fig-

ure 4.1.

Figure 4.1: AdsCan.dll architecture

With the new driver architecture, you don’t need to recompile your CAN

applications when you switch one CAN card with another.
