I have read ADAU1772 audio codec datasheet but there is no information about internal DSP's instruction set and how to program it. There is a guide for evaluation board with ADAU1772 but I do not have that board. What is more pins of my ADAU1772 are permanently connected to FPGA so I have to program it using FPGA. I just need information which registers inside audio codec I should write and what are possible instructions. Unfortunately I can not find any information on Analog Devices website.
The instruction set of the Sigma DSP family is not available.
The only way to create a program is to use the Sigma DSP software.
When you want to load this program into the chip, you can do this in several ways:
- using the Sigma DSP software
- using a microcontroller connected through i2c: but read the docs, it is not that easy!
- by telling the adau to autoload its program from an i2c eeprom
