Abstract: According to the principle of xPC target driver, solutions are put forward targeting the key issues of parameters transmission and base address lookup in development of xPC target drivers. The solutions involve block mask and selection of valid base address. Tests are conducted with an industry computer and a DIY PC respectively, and result shows that the drives with seven-channel A/D conversion can achieve 10 kHz while the signals can be visualized in real time. Tests prove that the proposed solutions are effective and the developed drivers are portable, which can help the development of xPC target drivers

Key words: xPC target, drivers, S-functions, parameters transmission, base address
