The revxlp is using a shift register - that's the trick

Done. Love it. thx @manna_harbour@lemmy.world and @petejohanson@lemmy.world for your help - and thx goes to frobiac from Munich for jumping on a mental health call and debugging the issues. it works so well now. my fav keyboard!

SOLVED

all solved... I had 2 dead pins due not really following the tape socket explanation in the readme. and when I pulled out the xiao, the socket came half way out. I now did solder a new xiao and checked all pins, now all good... phew! thx again! it chose the 12u miryoku firmware and it works

Just adding the back of the PCB - you can see some missing diodes there. For now I am pretty sure that is OK, as it's what JLCPCB has assembled as in the BOM/Place file.

@petejohanson@lemmy.world

I checked connections from XIAO to the board and also took off the bottom plate, alu, just to be sure there is no shortcut. When plugging into usb-c and turning on, the green led charge indicator is on, seems to charge. I was previously able to connect via ble, too.

All right, here is my build run, it is a success and should build a basic miryoku for revxlp - details here https://github.com/hansamann/miryoku_zmk/actions/runs/6761313214

When I double press reset to have the USB storage of the XIAO appear, it will bring up an error "can't complete operation because some data in ...uf2 can't be read or written. But I think it copies the 359KB of uf2 over correctly. Then Finder of course shows an error as the device resets into the keyboard mode... all expected, right?

Unfortunately it still behaves weirdly. The outer three columns don't do anything. the 4th column top is a 'w' then below r and then x... leaves me clueless. I used JLCPCB with the assembly service. On the back of the pcba, I can see some D's are not places, for example DU D_U2 / D_U4 / D_U3 / D_U9 / D_U8 - but I assume that is all OK. I added the not swap sockets ONLY on the back as the assembly should do the rest on that side of the PCB.

If you could point me to a ready made build for the XIAO-nRF52840 with a default keymap I am happy to try that out.

will try building with defaults... which I pretty much did to be honest. just mac style copy/paste is special. I will take off the alu back and chec the xiao ble connections. thx

Would you mind making it 36 keys, 3 Thumb keys? Then I am in to try it out... Looks like a great board.

Love it.

I am interested in the 3x5+3 version and would love to get Miryoku on it, plus of course the track pad needs to work, too. Is there an easy way, like a qmk workflow build that achieves this? Or another guide that describes it?

I still would love to build it but jlcpcb shows these mounting holes as not available... any better idea than just trying again every week?

Thx again - just printed the right side and was initially a bit worried about the snug fit, but after pushing it in a bit it simply fits perfectly!

let me confirm it was an issue with karabiner-elements... I totally forget, thx for the great comments @Tompi@discuss.tchncs.de and @manna_harbour@lemmy.world I now just realize that the Miryoku Colemak DHK is also not the default, but I'll just swithc that back to default and it will most likely work!

thx all!

Oh no many others, some a bit over 36 keys, like piantor and revxlp... But just using 36 typically.

Chocofi is awesome, too. Also built crowboard, and a self-wired skeletyl but right side unfortunately refused to work... Need more time to look into it.

Yeah the same and default alphas means Colemak Mod dh normally - I assume it's my fault and the key mapper... Checking in a few hours and will report.

Also excellent idea - will test Ina few hours. Although I think manna's comment will be the reason - using a key mapper on mac which turns my us international into Colemak Mod dh. Somehow my other keyboards are not affected, but it's my first qmk build... Maybe I need to exclude it specifically...

Omg I am using a keyboard mapper on my Mac, so far keyboards connected were not mapped again... Will check.

I also ran a workflow (https://github.com/hansamann/miryoku_qmk/actions/runs/5660097404) now and did set the ColemakDHK specifically but it still does not quite give me the desired outcome.

q w t ; z
a p r b g
x c d s v

is the left side, which is not really colemak mod dhk... am I doing things dramatically wrong? or is something wrong with my build @Tompi@discuss.tchncs.de - I can hardly imagine, what could it be? also I think the default qmk built worked from a main colemak layout perspective, so the keymap was correkt with the default...

I can confirm the uf2 flashing works - but with the uf2 flashed it seems to be using a weird keymap... top row starts with q - w - t - ; z for me... I am confused.. the thumb keys seem to work as expected .will try a workflow build with my settings.

oh wow, you guys are so amazint. trying this out in a second

cheapino reminds me a bit of crowboard, switches (chocs) directly soldered, too - but it's still one of my daily boards

honestly I just like to build them... I am somehow locked in to 36 keys now though and try to get miryoku onto it...

@tompi@Tompi@discuss.tchncs.de any chance community layout support can be enabled?

This sounds excellent. Will give it a try in a few hours and let you know. Maybe we can ask manna to include it into the official Miryoku builds, too.

Ok, that already helps - I know uf2 files and now to get them over from kmk. But need to work on making it create that u2f file :-)

Yes this will be the step 1 - right now I am not able to flash the default, that's most likely because I am completely new to qmk... Will put extra time in soon.

Now I built one... Trying to figure out qmk now, first time...

this already lookes great - are the stls available?

also just fininshed the hardware build and now - for the first time - try to get qmk on it. I cloned the repo just as in build guide and also installed qmk as per qmk docs. but when I issue

make cheapino:default:flash

I get

QMK Firmware 0.15.18 make: *** No rule to make target 'cheapino:default:flash'. Stop.

Any idea? I am also on Mac...

Looks amazing and I am just checking who else in our local Munich group wants to build it. It's on my list. Thx for sharing.

will zmk work with the rp2040 zero from waveshare? it's not ble/wireless here...
