crws Posted April 22, 2004 Report Share Posted April 22, 2004 Hi, I'm having a problem that I believe is easy to sort out but with me be new to all this it is not coming easly to me.Can some one shed some light on the situation, I am trying to implement a JK flip flop counter, which is fine until it comes to getting it to implement a set counting sequence of 1-2-0-2-3-0-2-5. I believe im having problems due to there being duplicate numbers, all ive got so far is a sequence of 1-2-5 continually.Any help will be much appreciated Quote Link to comment Share on other sites More sharing options...
hotwaterwizard Posted April 22, 2004 Report Share Posted April 22, 2004 Explain more. Are you trying to get Bianary numbers?Are you trying to get Decimal numbers?Are you trying to get Bianary Coded Decimal?A Number Display on a read out?Simple Led output?How many numbers Displayed at the same time?Be more specific.

crws Posted April 22, 2004 Author Report Share Posted April 22, 2004 Sorry i did say i was a novice. I am only after showing one digit at a time to a 7 segment display which hopefully will be powered by the ic chip which is a bcd to 7-segment decoder. The circuit will use when working a set clock for all jk flip flops and i think thats all the info i can give at the mo. Hope that helps Quote Link to comment Share on other sites More sharing options...
hotwaterwizard Posted April 24, 2004 Report Share Posted April 24, 2004 You could use a sequencer with this type of circuit to do the job.Hook something like this to the PROM Circuit.The Resistors are 1k ohm Quote Link to comment Share on other sites More sharing options...
hotwaterwizard Posted April 24, 2004 Report Share Posted April 24, 2004 Use this to hook up to the Night Rider Project in our Project Section Then hook up the BCD Decoder and the Digital Display. The Datasheet for the 7447 can be found here.http://www.ee.washington.edu/stores/DataSheets/74ls/74ls47.pdf Quote Link to comment Share on other sites More sharing options...
