ECET 456 Distributed System Design with Multiprocessing
Lab #5-B
Lab Objective:
Design an application program for PC. The program is to demonstrate the interface between measurement computing’s USB-1024LS board and PC.
The task is to receive 8 bit input from digital trainer into port B and display on the monitor.
Print the poem (8 lines), If nth bit is ‘0’, omit the nth line or if nth bit is ‘1’ print the nth line.
And output the data value on port A also.
