Advanced Device Driver Development

Advanced Device Driver Development

This training program covers three different types of device drivers. It involves implementing parallelport device driver, serial port device driver and block device driver.

A character device driver is one that transfers data directly to and from a user process. This is the most common type of device driver and there are plenty of simple examples in the source tree.Character device drivers may transfer data between a user-level process and the device using any scheme other than the system buffer cache. Character drivers control devices such as network cards, terminal devices, printers, and specialized devices such as robots, medical devices, and retail sales devices.

parallel port is a type of interface found oncomputers (personal and otherwise) for connecting peripherals. In computing, a parallel port is a parallel communication physical interface. It is also known as a printer port or Centronics port. It was a de facto industry standard for many years, and was finally standardized as IEEE 1284 in the late 1990s, which defined a bi-directional version of the port. Today, the parallel port interface is seeing decreasing use because of the rise of Universal Serial Bus (USB) and FireWire (IEEE 1394) devices, along with network printing using Ethernet.We use Parallel port Device Driver Development as a building block towards mastering Device Driver Development. We would implement Driver for 74LS24 chip and use ISSS1284 Standard.

The training program on Serial Port Device Driver Development aims at creating the driver from scratch. During the training, we would discuss in detail about data-sheet interpretation, underatanding the architecture of the serial port and the assicoated chip PC16550D, underatanding serial IO, RS232 protocol. Then the driver development would start.
