文摘Based on the in-depth research of the embedded device management system,analyze the process of the driver parameters delivery on kernel level particularly.According to this,expound the device driver 's working principle,structure and design methods especially.Finally realize the drivers of the character-based devices which can be dynamically loaded.Actual result shows that mastering the realization of the device driver mechanism and the process of parameters delivery with kernel can improve the embedded device driver development efficiency and reduce error probability effectively,thus saving the development cost and development cycle of embedded products.
