Touch screen with touch ponit data acquisition system is proposed in this paper based on ARM7 series LPC2210 microcon- troller and embedded operating system btC/OS-II, and physical layer circuit conversion between microcontroller and the host machine is completed. It achieves data communication based on the LIN bus. The system can acquire exact coordinates of the touch point and con- trol menu information on the host machine, and has features of accurate, reliable and fast transfer rates.
