Just saying hello Started by MichaelaJoy Yesterday at 6: I show five push-buttons but it can be expanded to eight.

But seeing all those diodes and the large amount of soldering required got me to thinking about a scanning type design that would require no steering diodes.

Thanks for this – I’d looked at de multiplexers briefly, based on what’s in my junk box, which ain’t much but the thing that stumbled me was the need to latch the output. Click Image to view fullscreen. It’s very basic, just 8 keys with a priority encoder so if more than one key is pressed only 1 output is high.

Thread starter throbscottle Start date Jul 4, Is it okay if I use this in an open dmm project? Click on it to enlarge.


CD4532 – 8 Bit Priority Encoder

Potentiometer Questions Started by norbss Yesterday at Sep 05, Posts: Also, if you need 10 or less push-buttons, you could use a CD decimal decoder in place of the CD, which has the advantage of being in a smaller package.

The 4-bit binary counter output goes to a CD 4-to decoder and to 4 D-Flipflops. After a few iterations on the simulator I came up with the design below. This image has been reduced to fit the page.

Moon Base Audio files: Hi, I’ve been looking to make a dead simple CV keyboard with keys that are etched like those you see in remotes: Welcome to our site! Well, I have plenty to work with now – massive thanks to both of you.

Ok, I had to try the priority encoder circuit also. You could add some pots to the outputs like a baby 10 to make it into an adjustable CV keyboard. Started by fastline Yesterday at 8: Wed Apr 27, 5: The schematic for the mofos mini controller just has a singular cv output.

I didn’t have a model for that in my simulator Electronic Workbench so had to use the CD for the simulations. The clock signal from the astable causes the CD binary counter to continually cycle through its 16 states. I used TTL, though. You might look at using a priority encoder as the front end. Best “radio button” latching circuit. Media New media New comments Search media. I ran into some timing race problems so the CD was added to give a clock pulse to the Flipflops in the middle of the decoder output pulse and avoid any glitches.


CD – 8 Bit Priority Encoder

When one key at a time was played, the result was “Unison. My version uses R-S flip-flops, creating a small delay to set each flip-flop after they have all been reset component values are fairly arbitrary at this stage and I haven’t given it a “zero” button, and missed out the switch symbols since LTSpice doesn’t have one The AND gate version I found latches using positive feedback, and is from here: Wed Cx4532 15, Wed Dstasheet 15, 2: By continuing to use this site, you are consenting to our use of cookies.

Question is, which is best? It’s shown below with a CD encoder and a CD 4-bit latch. You must log in or register to reply here.
