zedder Posted May 14, 2007 Report Share Posted May 14, 2007 Dear All,I am new here and I have a question concerning the protocol to be used with digital potentiometers for the purpose of "upgrading" a very old non-midi synthesizer to a midi compatible one.The aim is to not change the original electronic schematic and to replace the analog potentimeters with digital potentiometers and to have these digital potentiometers controlled by a PIC.But... there are at least 35 analog potentiometers to replace by digital ones and I don't know which protocol suits best for this job (I2C, SPI, other....) ?Does someone has experience with this ?Many thanks in advance !Zedder Quote Link to comment Share on other sites More sharing options...
stryd_one Posted May 14, 2007 Report Share Posted May 14, 2007 Weird, I thought I already replied to this a little while ago...Search the wiki and forums for 'digipot' and 'MBFX' and you'll find all that you need :) Quote Link to comment Share on other sites More sharing options...
