Hi,, do any of you have worked with this potentiometer before ? Cuz the data sheet has very little info about the use of the spi with the chip

Thanks

It works like any other SPI device.

yes,, i've noticed that after further investigation ,, it can be only written to not read from

ye si have used it , but it is not precise ..., it has 256 steps from 0 to 10k.
1 step corresponds to approx 33ohms .

its full value never reaches 10k
,first a command byte has to be send 0x11;
followed by data (digital) (0x00 to 0xff).
