I am trying to implement i2c protocol in ni-usb 6363 dac card. I am generate clock pulse (SCK) by using a PFI pin output and serial data by using a Digital output pin.
but I am facing problem in synchronization of clock pulse and DO as per i2c protocol.
is it possible to varied the digital output voltage of ni-usb 6363..?
the NI-USB 6009 ist most likely the wrong choice for this task. As a minimum requirement for I2C communication you will need hardware timed digital I/Os which the 6009 doesn't provide. Software timing will have way to much jitter to allow the communication to work at all.Please refer to the rest of the thread to explore alternative options.
Many years ago I successfully did similar to implement microchip programming with daq. I think DAQ can work as a IIC master device without any issue. Twenty years ago it was even so popular to use PC parallel port to do so.
