Thought I might ask here, sorry if I’m in the wrong place. But I just learned about Wooting’s rapid trigger (https://wooting.io/wooting-two-he), that deactivates the switch when it changes direction instead of when it reaches the reset ‘breaking point’.
My thought was if this would be able to be controlled on a regular MX switch and if such a program already exists? Since I’d prefer not to buy a Wooting keyboard and run their software. Seems like Razer has copied Wooting in their latest software (https://www.youtube.com/watch?v=c64yGHLO-TU&t=10s), but I’d prefer not to buy Razer products either. So looking for an open source program to control the trigger behaviour of the keyboard.
Hope my question is clear, thanks:)
For this you need an analogue sensing mechanism such as hall-effect sensors (as Wooting use). You can see some open-source reference designs for PCBs, Firmware, and switches using hall-effect sensors on riskable’s github to get you started. Technically you should be able to make a PCB like this and then use the same “switches” that Wooting use, though idk where they source them.
I think the dometyl keyboard (https://github.com/geoffder/dometyl-keyboard) was designed to use hall effect sensors with wiz switches. Not sure what is the PCB design that read the hall effect sensors.
If we just need digital, a comparator should be enough. However, wooting require 1 ADC for each switch, or at least some multiplexer. As it is unlikely for a single MCU to have that many ADCs, the pcb will likely require multiple chips like ADC0809 that can read 8 different analog outputs. Probably some more mux as well to reduce the number of pins required for the MCU.
