hi
i m doing a home theatre project for my college
so i m having some problem
could any one help
i m using pic16f72 and sound processor pt2258 (6 channel volume controller)
can any one write a code for me to interface them both
here is the datasheet link **broken link removed**
plz help me
i only want the master volume only + and - keys
 
Maybe you should consider the PT2327 from the same company, it only requires a DC voltage for control. It has 32 steps from 0 to 100dB so each step would be approx 3dB which is nearly the smallest change that is noticable. A 10dB sounds twice as loud. OR does this project require a microcontroller?

hi Paul
pt2258 is designed for home theatre systems and is i2c capable
i have designed the i2c part of it but i m stucked in the swicthes part
i want total 10 keys to operate the volume
master volume - +
front ch vol - +
rear ch vol - +
subw vol - +
center vol - +
so plz help me u can take my i2c code
here it is
