Hello all, I am an intermediate VHDL programmer and I have a project that requires me to use FPGAs for one portion of the project. The other portion of the project, I need to be able to send commands to Lab equipment via GPIB (IEEE 488.2) to measure signals from portion 1 of the project. Through some digging, I have found timing diagrams of the the GPIB handshake protocols, however there are 8 data lines that I cannot find any info on. for example, if I want to to measure a signal, which data lines go high or low to accomplish this task? There is a standard command library for C++ code to control GPIB, however I would like to avoid it if possible. Does anyone know of how I can do this? I searched for a IP core but I only found one and it was no longer supported. Thanks!!! Jonathan
