Re: Teensy 2++ Pin Question

The pins I'm thinking about using, PB6 and PB5 do have PWM. I just wasn't sure you could mix LEDs in with columns or rows and didn't want to assume.

Teensy 2++ Pin Question

I was wondering if it's possible to mix LEDs with ports used for columns on the Teensy 2++ ? I know you can't mix rows and columns but am wondering if it's possible to mix LEDs in a port ? Only need two LEDs for the design I'm working on, which opens up more pins for columns IF it's possible to mix ...

Thank you everyone, it's much clearer now ! The replies here made me go back and look at the PCB design again and to actually start following traces. Sure enough there are long columns in a few places. Matrix-Revised.png Now I understand how a " 6x22 " can fit on the ATMEGA32U4 by simply extending s...

Can someone post an example of how an 11 x 11 matrix might be wired to the Atmega32U4 ? I'm just not understanding how to fit 101 - 104 keys without splitting them up like the firmware builder shows. Not that far enough along in my understanding yet.

I guess understanding how the matrix is created is my issue then. I was under the impression that it should follow the physical layout of the keys in order to be valid ? An 11 x 11 matrix would be perfect for the ATMEGA32U4 but I'm not understanding how an 11 x 11 would work if following the wiring ...

ATMEGA32U4 vs AT90USB1286

Forgive my ignorance on this and the rambling, I'm still trying to learn and wrap my head around designing a keyboard from the ground up. Has anyone done a keyboard PCB using the AT90USB1286 ? I have no idea what the AU-ND and MU-ND designations mean and have no idea which one would be better suited...

you do not need to include LEDS in the layout editor, you can set LED pins seperately at the bottom of the pins page Perfect, thank you. What doesn't make sense is the pins in the firmware builder do not match the pins on the ATmega32U4 Even when the ATMEGA32U4 is selected. They do match on the Tee...

What I'm wondering now is where to find information on spacing for proper placement of the footprints on the PCB to make sure the keys line up properly and don't touch each other.

I'd like the pcb footprint placements to match the hole placements of the plate that swillkb spits out.

I'm just getting started in mechanical keyboards and am kind of bummed I missed V1 of these. They really remind me of the keyboards as a kid in the 70s and 80s. Really like that profile.

Well, I didn't explained myself very well. First, in a keyboard controller you will never use input and output in the same pin. Also, in the hypotethical case you first have to define the pin as the contrary state, it will never work like an input and an output at the same time. I was just trying t...

Thank you for the explanation. I was under the impression you had to know what pins to use and had to manually assign them on the Pins page. That's what I get for over thinking. I did read the thread on Box switches but have already bought them and kind of like the feel and sound the Navy's have. I ...

This is where I'm lost. I had no idea you could choose the pins yourself ? Thought you had to pick pins in some sort of order ?

This is what makes it so confusing...

What would you put it for the layout below using the Teensy ++ 2 ? That's really the only way I'm going to understand this I guess.

Okay, so the web page is showing the corresponding layout with how it would match up to the pins on the controller ?

I am not entirely sure how the matrix works but have a vague idea. Vague meaning I know when a switch or combination of switches is pressed, that results in a unique series of closed contact points being sent to the controller. Other then that, I'm lost. My matrix would be slightly mirrored but not ...

Switches are NovelKeys x Kailh BOX Thick Clicks Navy.

I don't have a source for the exact material but by the way you describe it, the backing you peel off of two sided tape might work. Cut to fit obviously. We have industrial two sided tape at work and the backing is a bit thicker than scotch tape but provides the properties you are describing. Just a...
