Hi
We are using the Zarlink ZL62044 device which is a 2 wire but non standard I2C.
I am am tryng to read and to write to the Zarlink ZL62044 with the NI-8451 using the Labview with the I2C read & write vi's.
Solved! Go to Solution.

Hey Eran,
The 8451 can only act as a master device on an I2C bus, and thus cannot send ACK signals, so I'm a little confused as to how your device is seeing the 8451 send an ACK signal. I believe there isn't any way to program the 8451 to not send a start/stop bit, as that's part of the I2C protocol we have set up.

Eran,
Actually, looking into this more I realized that that 8451 can send an ACK signal if another master is writing data to it. However, we are still unable to make it so the 8451 cannot send an ACK signal because the hardware on the 8451 follows the I2C protocol, which automatically sends those signals.
