hello,

I am trying to communicate with the impedance converter AD5933 through I2C. However, it seems that Analog Devices have adopted their own flavour of block reading and writing, cf. the datasheet p.27-29.

Using the machine.I2C library, I have not had success reading and writing blocks. I have checked, and the *_mem* functions do not yield the correct result with this device.

Cf. the docs, it should be possible to construct the calls the AD5933 specifies, however, I need to control the stop-condtion, which seems to be unavailable? Is this the case, or did I miss something obvious?


Please help.
Thanks!

I didn't find the right solution from the Internet.
