It’s very basic, just 8 keys with a priority encoder so if more than one key is pressed only 1 output is high.

Even better but credit where it’s due, it was ChrisP58’s idea to use a priority encoder, not mine! Moon Base Audio files: Display posts from previous: Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.

The 4-bit binary counter output goes to a CD 4-to decoder and to 4 D-Flipflops. Started by fastline Yesterday at 8: I didn’t have a model for that in my simulator Electronic Workbench so had to use the CD for the simulations.
Is it okay if I use this in an open dmm project? Thread starter throbscottle Start date Jul 4, Jan 14, Posts: Note that only four push-buttons are shown. Click here to register now.
Clock speed depends on expected worst case simultaneity. When a PB connected to the decoder output is depressed, the pulse from that output is used to latch the binary counter value of that PB position into the D-Flipflops.
I’m completely impressed and wish I’d had the idea datasjeet – thank you! Ok, I had to try the priority encoder circuit also. 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: Jun 01, Posts: You could add some pots to the outputs like dafasheet baby 10 to make it into an adjustable CV keyboard.

The clock signal from the astable causes the CD binary counter to continually cycle through its 16 states. Best “radio button” latching circuit. Forums New posts Search forums. The schematic for the mofos mini controller just has a singular cv output. To participate you need to register. Back in the day, I used priority encoders to interface with cd4523 key keyboard.
