I am using a LPT port from my PC to communicate with my device (CHIP), my device contain 60x8-bit registers meaning 60 different adresses, I need then to send data to thoses registers by adresing them and be able to read from them the contains choosing then respective adress then display them on a table (DUMP).Does anybody have ever done such an application, it is possible to have an example?I am using LAbview 7.1
Thanks in advance for your help

Reading and writing to parallel port is done by using VISA. Call VISA Open to open the resource. The you can call VISA Write, VISA Read to write and read. At the end call VISA Close. The resource name can be determined from MAX. Go to Devices & Ports >> Ports then you will see a list of the ports in your PC. Mine has one parallel port named "ASRL10::INSTR" and has the alias LPT1.
