From PCA9541 spec, the device address can be 0x78 to 0x7C.
However 0x78 to 0x7C are reserved for 10-bit addressing.
So the device address will expand to 0b11110xx 0b1111xxx .
Am I correct?
From PCA9541 spec, the device address can be 0x70 to 0x7F,but from 0x78 to 0x7F is as Reserved I2C-bus addresses must be used with caution.
If my device address is 0x78, does the address will expand to two byte address? Or still one byte address?
i2c-tools only support to 0x77.
I don't know why your IIC tool only support 0x77 maximum,but this should be still one byte address.
