LC75341 is a digitally controlled analog tone control for audio applications. You can control parameters such as Bass, Treble, Volume and gain through its digital serial data transfer. The data is a 40 bits wide, 8 bits for the address and the 32 bits is the controls data. It is very unusual and you cannot use the microcontrollers built in UART, I2C, etc. I can’t find anywhere on the internet any examples of programs to control this particular IC so I made one for myself. I want to share the code for anyone who want to build this kind of project. The code is simple and I will only share the part of the code that sends data control to the chip. It is up to you to modify it according to your needs.
