Filename: test_6527.zip
Requirements: View

This example enables change notification using the NI 6527 in CVI. The example allows the user to specify the device number and the lines that will detect rising and falling edges on the front panel. Once the device is configured for change notification mode, the device generates an interrupt each time a rising or falling edge is detected on the specified lines. This interrupt is handled by a function in the program that simply reads all 8 lines of port 0.
