HID Remapper: mapping basics

[@bullzebub]

so i made this... it seems it detects devices connected to the pico but i get no output. what could be the reason? under linux. ive modified the dev/hidraw permissions

[@jfedor]

Can you submit a GitHub issue with all the details?

[@jimmyandersson4084]

Where can i buy the adapter so i can hid remapp?

[@jfedor]

There's a separate video that gives you all the options, but for example you can buy the Feather RP2040 with USB Host from Adafruit.

What output is FN key?

[@jfedor]

The "Fn" key doesn't send anything to the computer, it's handled internally by the keyboard. Unless we're talking about Macs, then the key does send something, but I don't know what.

[@jimmyandersson4084]

@@jfedor If i want to change place on win key and FN key. i manage to make fn key as a win key. I have to reconnect the keyboard everytime i start windows, is there a solution for this, if i dont do that the keyboard dont make any inputs...

[@jfedor]

@@jimmyandersson4084 This might be a known issue, #83 on the issue tracker on GitHub, and there are other related ones, with people having this problem when suspending the computer then waking up, or using a KVM switch. No fix currently (except I think the dual Pico version is not affected).

[@CrytenJones]

Quick question for you, I really want to use this to take a number of PC joysticks and map them though to windows as a unified device or devices.. Is that possible?

[@jfedor]

You can connect multiple joysticks to HID Remapper using a hub. It will be visible as one device on the PC.

[@CrytenJones]

@@jfedor Thanks, and what would you say are the limitations? e.g. max button and axis counts etc? my setup would have 13 axis total and probably 128 buttons.. Do you know / think that the USB output from the mapper could be modified to be a composite device that consists of more than one 'virtual' device? What I am trying to build here is a hardware version of the vJoy / Joystick Gremlin combo

[@jfedor]

@@CrytenJones Adding more buttons and axes is not an issue, you'd just modify the report descriptor and recompile, making it appear as multiple devices would require more significant changes...

[@CrytenJones]

@@jfedor Yea I figured, the issues is (i believe) that the windows limits the axis and button quantities that any one joystick can have that being 8 and 128 respectively and given that the target here is to increase the number of outputs .. eg button 1 on layer 1 = button 1 / button 1 on layer 2 = button 51 etc. I guess what I am looking for is for each input device to have a matching input device but with the mapping software in the middle. Obviously I could just use one mapper device per input device, but there are some functions that would want to effect all the connected devices. e.g. a global shift button (hold for layer 1, release to return to previous layer I totally understand that this is not currently what the project does, but I guess I am asking if you think that it's feasible using this as a starting point and b) if you are interested in helping out :-)
