I went with Aqua Zilents, as they seem highly recommended for tactility without too much noise. A bit of sandpapering on the wide tips of the pins makes a large difference. I have some ideas on how to improve slave and master encoder pulse detection that will help (option 1 like) , but it's be impossible to fix it 100% as users still can spin the encoder faster than what is possible for us to register along side of all the other keyboard functionality. If you followed the optional step to solder I2C resistors, hardware support should already be there. This article mainly applies to revisions 2 to 2.5 of the Iris keyboard. The "Altoids Can": Iris Rev 2 w/rotary encoder. Jay Phantom liked Face Tracking USB Missile Launcher. Right half PCB Items needed for Build: 1. I guess just polling multiple times wouldn't really solve anything regardless of delays, since you'd still have the problem with the rest of the loop taking too long a time. Learn more, We use analytics cookies to understand how you use our websites so we can make them better, e.g. The owner of keeb.io, bakingpy and QMK collaborator drashna were kind enough to provide some answers, and with their answers I was also able to find some unused pins in the firmware. I kinda wonder how that crystal got dented in the first place… Shipping possibly? The gist I need to figure out is given 2 values, find the shortest delta between them and the direction (positive vs negative) while also taking into account wrapping. Note: KC_VOLD on my PC changes vol by 2%, so this is 24 registered ticks (48% / 2). The way I understand it, currently there are several solutions: As for 1, revising the encoder state change handling, I can imagine the slave reading the state changes and buffering the resulting events for them to be handled by the master could work. Want to build a keyboard but need a few more keys? I’m researching whether I can do modifications to the board, such as adding an OLED screen or using a rotary encoder. Testing on my encoder here's what I noticed so far: RGBKB Sol R2 Here's a summary of the build steps: Add 2u stabilizers to PCB (optional) Solder rotary encoder (optional) For Rev. The Iris is open source and uses an on-board controller, so you can have the boards fabbed and do a lot of SMD soldering, or get a pair of PCBs with all of that already done. Reddit user /u/LurkerMcNoPost has made a post of his Iris that succesfully uses a rotary encoder, with links to code he wrote to make it work. It might be undesirable as that could lead to heightened latency. This is just to fix the master encoder behavior, slave encoder part is more to do with what I said "some changes to how we track encoder state". My type casting was wrong. Iris Plate Kit 3. I guess that could be a secondary bug though, as it doesn't sound like it should be affected by the bug described above, but I thought I'd mention it in case it is connected somehow. @XScorpion2 not to worry, I very much appreciate your effort! For example, disabling rgb matrix which is 1-2ms per keyboard tick was enough to improve slave encoder behavior too. @skbolton You should be able to test this if you have Git set up by running: This will leave your master branch intact so you can just check it back out and compile/flash again to restore your current Iris firmware. “They were crap idea back then, still is”. 1 x rotary encoder with knob from Keebio (2 are supported, but I couldn’t think of a use for a 2nd one) FR4 plates for Iris from Keebio; PCBs for Iris from Keebio; TRRS cable (used to link the 2 halves together) … When one side’s underglow lit up but not the other, [sinbeard] busted out the ISP programmer. I'm up for helping out with testing as well if there's anything that needs to be checked/verified. There are split boards that do use I2C, such as the Corne keyboard (also known as the Helidox). PEC12R-4217F-S0024 (24 Dents, 24 Pulses) - https://www.digikey.com/en/datasheets/bournsinc/bourns-inc-pec12r, Slave: The Iris is open source and uses an on-board controller, so you can have the boards fabbed and do a lot of SMD soldering, or get a pair of PCBs with all of that already done. Just solder in your switches and you're done! So anything that slows the keyboard down or fast spinning of the encoder will cause it to miss out on a pulse. Currently I'm having a very heated discussion about where to go for lunch with the in-laws and wife in the car in the middle of no where... Oof. Are there updates on this issue since the last time? When one side’s underglow lit up but not the other, [sinbeard] busted out the ISP programmer. PCBs for Iris from Keebio. A common complaint of the ergodox is that its thumb keys are a stretch for many users to reach. For the keycaps, I chose MDA Big Bang 2.0, which is one of the few keycap sets that is sculpted per-row in a manner appropriate for split keyboards. I have a few ideas on how to fix this. But in the end, he found the problem — a dent in the crystal — by staring at the board. I’m making the move to a split ergonomic keyboard as a reponse to occasional wrist pain when working at a computer.

So while the on/off overlap is slightly different, it still comes down to how fast we poll the pins state. 150 x Mill-Max sockets (not pictured above), 1 x rotary encoder with knob from Keebio (2 are supported, but I couldn’t think of a use for a 2nd one), TRRS cable (used to link the 2 halves together). I'm not sure if the display needs to be written to as often as happens now for example, and perhaps I'm using the OLED API in a suboptimal way. Got a link to the encoders you are using? I performed make clean beforehand and flashed both halves. 2u PCB-mount MX stabilizers(optional) 8. Sign in Everything went according to plan until it was time to flash the firmware and it didn’t respond. In order to do that, I’ll need some free pins on the microcontroller. There exists support for SSD1306 based OLED displays in QMK, based on I2C communication. This article mainly applies to revisions 2 to 2.5 of the Iris keyboard. I found the above diagram in the documentation from Keeb.io. I set out to see whether all those pins see use, so I can use some of the pins for my own modifications. I’ve built an Iris keyboard last week. It might be necessary, but I hope we'll be able to improve performance. Given if you swap master to the other hand it works fine, the initial guesses are around the split_common/transport.c code, rather than the encoder.c detection code. Admittedly, this is pretty close: the column stagger is small. I have heard whispers that using #define SERIAL_USE_MULTI_TRANSACTION in the keyboards config.h file has helped general serial communication issues, so I would be very interested to see if it helps here, though it requires compiling & re-flashing both halves.
