Hi, I am using CY7C68013A (EZ USB Cypress development Kit). Any idea how to control a GPIB device using USB port of this? Please help
Do you mean to implement a proper USB Test and Measurement Class (USBTMC)?

Or will any "proprietary" implementation do?
Try googling for cheap USB-GPIB adaptors to see what they do - some of them enumerate as COM ports and have a simple RS232-like protocol...
I am working with EZ USB development kit ( CY7C68013A). The aim is to achieve a USB to GPIB conversion. ie. to be able to control a GPIB device using USB interface. Presently I have written a code wherin the Ports A, C and E are used to represent the 24 control and data lines of the GPIB protocol. I have tried to compile it using Keil uVision 3 compiler (evaluation version). Though there are no compilation errors shown, while building it, an error - L250 - 'Code Size Exceeded the Limit' is being shown. I am stuck at this point for long. Please help me to proceed with the project.
For a start, why such an ancient version?
"error - L250 - 'Code Size Exceeded the Limit' is being shown. I am stuck at this point for long"
So you either need to remove the evaluation limit - ie, pay for a licence - or find a different tool.
Or reduce the size of your code.
