Ay ganun ba yun. Susubukan ko pa naman sana yung digital potentiometer ng Maxim, may malaki din kayang effect yun pag iyon ang nilagay ko sa input as volume control? Iyan kasi sana ang magkakasama sa project ko, digital pot as volume control, standby and mute using Pic16F54

No harm in trying sir,  diyan tayo matututo, anyway, hobbyist ito at wala tayo schedule na hinahabol, wala din customer na magrereklamo.

Pero if were you, kung digital volume potentiometer lang iyon,  may suggestion ako.   why not use iyong DR100W equalizer na ginagawa sa kabilang topic under DR100W,   advantage
- digital volume control
- digital selection of input (2 steeo selection)
-  digital speaker attenuation
-  digital  Bass  +/- 14 dB
-  digital Treble +/- 14 db
- digital Gain

on package on single IC,  please see TDA7449,  If you like with surround sound,  use TDA7442D

the above is a nobel IC to adds life to your favorite music,  yet +/- 14dB is not good enough for common bass satisfaction
so,  the designer added the PT2389 preset equalizer to add more environment listening,  rock, pops, classics, etc.

ang challenge dito ay ang Noise,  dahil digitally processing and control and mga ito,  ang digital data ay mayroon effect na maririnig sa speaker.  Kung hindi carefull ang grounding,  kapag nag send ka ng I2C data,  maririnig mo ang noise sa speaker, paano na kung ini-increase mo ang volume at puro 'tit-tit-ti-tit" maririnig sa speaker everytime na pipindutin mo ang volume +,  volume -.

Sir, biro lang po, napagaliitan na ako sa pagbibiro eh, pero biro pa din.   

pero ito hindi biro, dahil po ikaw ang number 1 supporter ng 1diy, special delivery na daw po pati iyong ibang toys mo, pinapahanap ako ng ibang chipset compatible sa DR100W  para sa iyo na lang daw po ang experimenter.

If I remember right,  ang pcb design ng DR20W ay magkahiwalay ang Ground ng logic at saka Powersupply/analog.

In your future integration with other digital systems, baka kailangan na maglagay ng inductor between the 2 grounding systems.

 sir, mayroon ka rin bang pinagkaka-abalahan?  O, Paminsan minsan nagpapadaloy ka din para guminhawa ang pakiramdam, kasama na daw iyan sa Hobby,  hobby na din pala.

mayroon po bang general at golden rule na technique para maiwasan ang effect ng mga data noise sa analog signal,  kung ma-amplify ng amplifer ang IR signal, I2C, SPI, UART data, parang may naririnig sa speaker na may naipit na daga.
