Presented in this paper is the development of the driver for the data acquisitioncard with a peripheral component interconnection (PCI) local bus on the ion cyclotron rangeof frequency heating (ICRH) system.The driver is mainly aimed at the embedded VxWorkssystem (real-time operating system) which is widely used in various fields of real-time systems.An efficient way is employed to develop this driver,which will advance the real-time control ofthe ICRH system on the experimental advanced superconductor tokamak (EAST).The driver isdesigned using the TORNADO integrated development environment (IDE),and implemented inC plus language.The details include the hardware configuration,analogue/digital (A/D) anddigital/analogue (D/A) conversion,input and output (I/O) operation of the driver to supportover five cards.The data acquisition card can be manipulated in a low-level program and meetthe requirements of A/D conversion and D/A outputs.
