Implementation of Nibble Mode communication using Parallel Port Device Driver. 1. Host signals ability to take data by making the Busy pin low. 2. Now peripheral or writer responds by placing First nibble. Writer Writes on Data line, on the … Continue reading
This project implements the protocol, for data transfer between a personal computer and a parallel peripheral interface, under NIBBLE MODE. The protocol has been implemented by using polling method for checking the status of the peripheral device and the host. … Continue reading

You can find the chipset mounted on your motherboard . using coomand ==lspci on the terminal will give ou list of all chipset for audio card , usb ,serial, parallel ,vga …….etc
A parallel port can generate interrupts when the voltage level on a certain input pin changes. The parallel port has to be instructed explicitly to generate interrupts and it is also possible to inhibit interrupts (e.g., while serving a previous … Continue reading
Succesfully implemented the parallel port outb operations using 8-led array!!! I had firstly make a sculldev allocate memory to it so that i can map the file_operations through the cdev_init and cdev_add operations and then map the parallel port address … Continue reading
Memory-mapped I/O (MMIO) and port-mapped I/O (PMIO) (which is also called isolated I/O) are two complementary methods of performing input/output between the CPU and peripheral devices in a computer. An alternative approach is using dedicated I/O processors—commonly known as channels … Continue reading
PARALLEL PORT A parallel port is a type of interface found on computers (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 … Continue reading
An Introduction to parallel port A parallel interface for connecting an external device. Parallel port is basically used to transfer data parallely . 8 bits of data is transmitted at a time in parallel port.On PCs, the parallel port uses … Continue reading
PARALLEL PORT Parallel port is the mostly used for interfacing line printers. It was introduced by IBM in early 1980′s. Earlier there was no standard defined for parallel port interfacing. Every company has their own standards for interfacing parallel port. … Continue reading
Implemented Compatibility Mode. Implemented Nibble mode for single and multiple bytes. Implemented Byte mode for single byte. Working on Byte mode for multiple bytes.
