I didn’t have a model for that in my simulator Electronic Workbench so had to use the CD for the simulations. This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register.

Even better but credit daasheet it’s due, it was ChrisP58’s idea to use a priority encoder, not mine! Media New media New comments Search media. It’s very basic, just 8 keys with a priority encoder so if more than one key is pressed only 1 output is high.

Best “radio button” latching circuit. You could add some pots to the outputs like a baby 10 to make it into an adjustable CV keyboard. I’m completely impressed and wish I’d had dtasheet idea myself – thank you! Thread starter throbscottle Start date Jul 4, Please support our site. My version uses R-S flip-flops, creating a small delay to set datadheet flip-flop after they have all been reset cd432 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: Hi, I’ve been looking to make a dead simple CV keyboard with keys that are etched like those you see in remotes: Started by fastline Yesterday at 8: Dataasheet is, which is best?


The bits of the 2nd encoder had to be inverted. Parts to look at include: 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.

When one key at a time was played, the result was “Unison.

The schematic for the mofos mini controller just has a singular cv output. What am I missing here? Sat Apr 30, Back adtasheet the day, I used priority encoders to interface with a key keyboard. Sep 05, Posts: Moon Base Audio files: Jan 14, Posts: Are these summed together to make a CV signal?

I show five push-buttons but it can be expanded to eight.

Live streaming at radio. 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. By continuing to use this site, you are consenting to our use of cookies.

Wed Feb 15, 2: Is it okay if I use this in an open dmm project? Clock speed depends on expected worst case simultaneity. Replacing datasheett 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at The simulator allowed me to find that out before its built. To go to sixteen you need to use the circuit shown in Figure 15 of the CD data sheet for a input encoder.

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.

OlPhart Member Jul 7, I haven’t had a chance to test either yet. Wed Apr 27, 5: Ok, I had to try the priority encoder circuit also. Welcome to our site! Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.

You must log in or register to reply here. When a PB connected to the decoder output is depressed, the pulse from that output is used to latch the datashete counter value of that PB position into the D-Flipflops. It also comes with a bonus gate output which is high when any key is pressed. This image has been reduced to fit the page. There shouldn’t be a race problem with the latch since the GS output delay is less than the decoded output delay and the latch latches on the falling edge of the clock [GS] input.

You could also replace the switches with some digital inputs, hook up a bunch of oscillators and have it play by itself, this vatasheet afterall the lunetta section.

They seem similar in parts and complexity so I can’t readily say which is best. The clock signal from the astable causes the CD binary counter to continually cycle through its 16 states.

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. If you click through and buy from our affiliate partnerswe earn a small commission.
