Implemented Compatibility mode. Implemented Byte mode. One problem: System hangs during data transfer. On the removal of wire, system resumes and data is received on the other system.
Implemented nibble mode for 1 byte. working on Byte mode…
Before writing to the port i m setting the value of Control register by setting the its 5th bit at LOGIC 1. and after performing write operation i am checking the status of control register… I am surprised as the … Continue reading
LED’s Are glowing properly with the user pattern…….
Successfully Implemented the Compatibility mode(IEEE 1284-1994) On LED 8 array.
We have Successfully Interfaced stepper motor with parallel port and tested following modes of operation: 1. Half step sequence Clockwise and Anti-clockwise. 2.Full step sequence Clockwise and Anti-clockwise. 3.Eight step sequence Clockwise and Anti-clockwise and successfully controlled the speed of motor … Continue reading
I have completed the 3 modes of parallel device driver i.e compatibility mode, byte mode and nibble mode. Working on the ECP and EPP mode. Successfully implemented man page creation and development. Working on customizing them as per the needs. … Continue reading
what is the difference between memory mapped io and port mapped io. and please tell me , parallel port and serial port which memory mapping followed??
our realistic work: compatibility: sends one byte data on data port line and take the output by leds, nibble mode: sends data on upper 4bits of the data port and receive by the upper bits of the status register . … Continue reading
I am currently working on Nibble mode of parallel port and we successfully transferred bytes of information from one PC to another using delay method but, facing problems in handshaking(unable to change control bits )….i want some information about handshaking … Continue reading
sir, i have completed the parallel port driver in NIBBLE mode……But not by handshaking….(by using delay). in handshaking our status is ->control have reached from peripheral to host but we are not able to receive the control from host to … Continue reading
in Nibble mode… -> can we use a single bit in hand_shaking in the parallel port driver..? -> which bit of the control register should i use to handshake->1.strobe bit, 2.autofeed bit. Please tell me the procedure of handshaking in … Continue reading
hows inb and outb work internally? getting problem in handshaking through strobe pin in nibble mode. how can i do it?
