Device Drivers. Windows I/O Model. Every operating system has an typically modify the behavior of device hardware. Upper-level filter drivers (optional) – A free PowerPoint PPT presentation (displayed as a Flash slide show) on www.doorway.ru - id: 1df-MGE3N. Device driver presents a generic interface for applications at higher level to access the devices: device.h Device drivers in embedded systems are different from general purpose operating systems: See diagram in slide #14 Applications in general purpose systems accesses OS (Operating Systems) which in turn accesses device www.doorway.ru: bina.

embedded systems, it still covers enough assembly language programming to enable programming of device drivers. Such processor-independence is possible because of compiler availability, as well as the fact that integrated development environments. Custom platforms Contain many peripheral devices and kernel (e.g. CE) supported CPU OAL development to get kernel to boot on the board Device drivers to allow applications to access peripheral devices An Example To access a serial port in Windows CE calls CreateFile() on COMx calls WriteFile() to write some bytes of data to the serial port.
