1 Customizing xPC Target™ Drivers

• Good C programming skills

• Knowledge of how Sim u link simul ation works, for example, t he type an d

order of calls

• Knowledge of writing S-functions and compiling those functions as C-MEX

function s. This includes a comprehensive kno wledge of Simulink callback

methods and the Simulink

SimStruct functions.

• Basic knowledge of Real-Time Workshop

• Understanding of I/O hardware. Because of the real-time nature of the

xPC Target software, you must develop drivers with minimal latency.

Most drivers access the I/O hardware at the lowest possible level (register

programming). Therefore , you m ust understand how to control the board

with register information.

• Know le dge of port and memory I/O access o ve r various buses. Y ou need

this information to a cces s I/O hardware at the register level.

• Knowledge of PC hardware fundamentals and internals
