Hi, I have term homework but I have a little help, I have no idea about how to do it? Can someone explain to me, how can I design this project? I investigated the family guide of MSP430G2 but there is no explanation about the LPT. Many thanks.

Write down an interface for a LPT port using MSP430G2 LaunchPad. The hardware interface for the LPT interface is based on D-Sub 25 pin connector. Data will be sent by using Centronics mode at a data rate of 120 kBps.

Detailed information about LPT interface can be found in these links

Since this is homework assignment you have to do the work yourself.
Begin by getting a large sheet of paper and a pencil.
Write down and draw out what you have learned about DB-25 Centronics connection as follows:

Write out pin-1 to pin-25.
Write out the function of each pin.
Write out the signal direction of each pin.

Draw a block diagram of a Centronics mode device with 25 connections to a MSP430G2 LaunchPad.

Draw a flow chart of what is supposed to happen between a Centronics mode device and the MCU with reference to the function of each pin.

I just wanted to consult. Of course, I should do the work. I didn't mean anything else. Thank you for your help. I appreciated.
