rduino Nano as controller
To score 3 consecutive posts of my own, I might as well share the code with you for using the Arduino Nano for controlling the 2xAK4399 dac.
I wrote an instructions .pdf as a manual to the whole procedure of replacing the original controller. Read it carefully before starting please, it also gives an idea of the work to be done and the skills required. The file is too big (4.8Mb) for uploading here, so you must download it provided link.
The software doesn t need much attention, so you don t need to be familiar with programming. Just follow the instructions. Two versions are provided, one for AK4113 and the other for AK4118 boards. Software is only tested on version 1 (AK4113), but when using the AK4118 version, it should work on version 2 too.
