Hello everyone,I have been learning about microcontrollers using a BASIC stamp chip and would like to know if it is capable of decoding a rotary? If so, does anyone have a schematic and PBASIC code sample that would work? Thanks in advance!!

Well, a stamp is certainly capable of decoding a rotary encoder.... just as a 50 tonne piledriver is capable of cracking a walnut :-)if you go to Leo's site at www.betainnovations.com there's a schematic etc for a decoder that will decode 3 rotaries using a single PIC - total cost of about $10 in parts. Far more economical than using a stamp.Richard

DavePICs work great for decoding rotary encoders. You can do any needed contact debouncing in firmware and have capacity left over for other functions. For example, by timing the speed of rotation you can change the encoder's function: slow turning increments something in steps of 1, while turning fast increments by steps of 10.Mikewww.mikesflightdeck.com
