Design of Resistance Touch Screen Based on S3C6410 Embedded System

Abstract:

This design uses Samsung ARM11 S3C6410 microprocessor and 4 wires resistive touch screen as the hardware foundation. Based on the hardware structure, the touch screen application is developed. System performance has been improved by means of the algorithm optimization of the sampled data and software filtration method, and lead to a strong practicability. In the end, three-point calibration algorithm is introduced for the offset problem of the screen coordinates, then the calibration matrix is decided by the selection of three-point, and then using software implementation to realize the calibration of point-to-point mapping relation, and finally make it more accurate in practical applications.
