Alkex Posted August 13, 2005 Report Share Posted August 13, 2005 Hi there,I was looking at possiblitys of automating resistance between two points rather than CV voltages to one point.the circuit below allows us to increment/decrement the resistence of a digital pot using only two switches.http://www.maxim-ic.com/appnotes.cfm/appnote_number/1118I havent much of a clue with electronics, but I was thinking that maybe a change in this circuit could enable us to control these digital pots with Dout pins ...Would anyone know a way of doing this?thanks in advance,Alex Quote Link to comment Share on other sites More sharing options...
moebius Posted August 13, 2005 Report Share Posted August 13, 2005 Hi,You might be more interested in using Digipots directly controlled by PIC. Captain Hastings Did this with Analog Devices AD5204 chip and modified AOUT driver, check:http://69.56.171.55/~midibox/forum/index.php?topic=2556.msg17995#msg17995Bye, Moebius Quote Link to comment Share on other sites More sharing options...
Alkex Posted August 13, 2005 Author Report Share Posted August 13, 2005 Moebius,This was just what I was looking for! Thanks to you and Captain (Hastings) <-my place of birth! ;D Quote Link to comment Share on other sites More sharing options...
