USB-8452: How to address a device with 16-bit register address

USB-8452: How to address a device with 16-bit register address

Dear All,

I am using an USB-8452 board to write/read registers of a device via I2C.

The device is peculiar, in sense that the register address is not 8-bit but 16-bit.

For example, I want to write 0xAA into register 0x1234 of a device with 7-bit slave address 0x7B (see snippet).

If I use NI-845x VI's I get "Error -301743 occurred at NI-845x I2C Write.vi:4470003" and "NI-845x: The slave did not acknowledge a data byte transmitted by the I2C master."

Is there some way to ignore the NACK?

Thanks for your attention
