Design and development of wiring harness test based on S3C44B0

Purpose – The purpose of this paper is to introduce a design method of an embedded advanced RISC machines (ARM) hardware circuit using the microprocessor S3C44B0 as a core according to a testing principle of wiring harness.Design/methodology/approach – The microprocessor module is designed with the S3C44B0 of Samsung Corp. The microprocessor send test instructions to the wiring harness circuit, receive and store the test data, get and display the test results by the liquid crystal display, and the wiring harness testing circuit is implemented by complex programmable logic device. The uClinux operating system is transplanted into the ARM hardware platform, and the developing and loading code of the uClinux device driver and a basic flow chart is given.Findings – The combination of S3C44B0 and uClinux embedded microprocessors achieved a powerful wiring harness tester driver development. This structure leads to a flexible configuration and convenient extension.Research limitations/implications – A Linux deve...
