Is there a newer document than the Data Sheet Rev. D availble?
I was trying to contact the AD5593R over a Rasberry Pi.
The address Pin was on high.
The documentation says the slave address byte consist of 0 0 1 0 0 0 A0 R/W.
In my case the address should be 0010 0010 (0x22) for write and 0010 0011(0x23) for read. The Raspberry told me that the address is 0x11.
Meanwhile I have found a hint on your Webpage that the address with 0x1_ is the correct one (switched over one bit and throw out R/W bit).
Is the R/W bit switched to another place?
I could read all informations from the AD5539R, but I could not send any commands to it.
The try to activate / deactivate the internal reference voltage with following command had no effect on the REF-Pin as documented at the Data Sheet:
sudo i2cset -y 1 0x11 0x0b 0x0200 w # activate internal reference voltage => without effect
sudo i2cset -y 1 0x11 0x0b 0x0000 w # deactivate internal reference voltage => without effect
sudo i2cset -y 1 0x11, 0x05, 0x0007 w # set IO0 - IO2 as DAC
sudo i2cset -y 1 0x11, 0x10, 0x8e00 w # send some value in the middle to DAC0 (also 8001 and 8fff tested) => without effect
sudo i2cset -y 1 0x11, 0x50 # set read back for DAC0
sudo i2cget -y 1 0x11, 0x90 w # receive the Status form DAC => receive some datas, on each power up different
The test where made with RaspberryPi 3 B+ and the ADAC-CLICK board from MicroE (part number microe-2690)
