Other Parts Discussed in Thread: DS90UB926Q-Q1
Good day!
I am using a pair of DS90UB925Q-Q1 <---> DS90UB926Q-Q1. The master is on the serializer side. The FM24VN10-G memory chip and the M41T62LC6F clock are connected to the deserializer. To access remote devices, I register the registers: 0x03 -> 0xda; 0x07 -> 0xd0; 0x08 -> 0xd0. In this case, only access to the M41T62LC6F (address 0xd0) is defined. It does not matter. I tried instead of 0x03 -> 0xda to do 0x17 -> 0xde. The result is one: when the master scans the I2C bus, I see only the serializer (address 0x18) and the deserializer (address 0x58). Nothing else!
When I started to understand, I found out that there is no answer from devices connected to the deserializer.
The graph is obtained directly on the terminals M41T62LC6F (FM24VN10-G). It shows that the address (0xd0) is correctly issued, but there is no confirmation. With what it can be connected? What am I doing wrong?
thank
