I am trying to read data from ltc2991 sensor through i2c. My master sends the slave address 0x90 (write), 0x91 (read) and trying to read data from memory location 0x0B.
I have received ACKs from the slave, however, it always reads 0x00 for the data.
Also, my master device is SP605.
I was configuring the device with wrong values, after I changed them, they were reading correctly!
Can you send a schematic and a scope shot of the i2c transaction please.
