So I made DIO[0] and DIO[1] as SCL and SCK for both I2C Master and I2C SPY. I first click "Receive" in the I2C SPY window: And then I click "Write" button in the I2C Master: But I dont see any capture on I2C SPY: Not sure why this isn't working.

I tried running both I2C spy and I2C master simultaneously on different DIO pins and connect them in a loopback with pullup resistors. But it isn't working. For example: I2C master: DIO[0] as SCLK output, DIO[1] as bidirectional SDA I2C spy: DIO[2] as SCLK input, DIO[3] as bidirectional SDA I attached pull up resistors (2.144K) to the SDA and SCLK lines with VDD=3.3V DC which I generate using waveform generator. I activate I2C spy and then run I2C master. I tried this but it doesn't seem to work. It gets stuck on a window "Transferring data" but never ends. When I click cancel, it shows "Error!" in the I2C master window. Is their anyway I could possible do I2C loopback with protocol analyzer/logic analyzer ?
