● Slave Address Sets the slave address of the device. This

affects all I2C/SPI communication. The codec slave address

for DA7322 is 0x34 and this is the 8bit value (34h for Write,

35h for Read).

● Find Finds the register address location entered into

the ‘Reg. address’ field control of the GUI and highlights the

location of the register if found.

● Send Sends a single byte of data to the device using

the Slave Address, Reg. Address and Data to Send.

● Read Reads a single byte of data from the device using

the Slave and Reg. Address.

● Find Finds a control matching a full or partial register

name, a control bit name, or a register number (e.g. R23 or

17h). Pressing ‘Find’ repetitively will step through all matching

items.

Note 4 If the Device Address does not match the port numbers on the

device, this can be used to control/read any other device on the

I2C/SPI bus.
