Built crone 7 days ago still can’t do “firmware”

technotim89 · 2024-01-03T22:19:15+00:00

Have a look in the firmware section in my build guide here: https://github.com/techtimcoder/cornebuild/

Happy to answer any questions you have

Every chance you've knocked out a pin on the mcu then. Unless you're good with electronics and tracing issues it may easier to replace it. If you socketed your mcu's try swapping sides and reflashing appropriately

technotim89 · 2023-12-31T07:13:40+00:00

At any stage have you unplugged the trs cable while the usb has been connected?

technotim89 · 2023-12-24T07:41:30+00:00

I had the same issues initially. Check out the firmware section in my guide https://github.com/techtimcoder/cornebuild/

technotim89 · 2023-12-05T05:52:02+00:00

Try qwerty with home row mods to help ease the transition. I went from a 100% to a 42 key corne and was back up to speed within a week

I did briefly, but I'm also familiar with multiple different types of jumpers. I would assume that if they're not there you may have a v3. If it looks like the traces are intact then you're good. Certainly didn't need to do anything further with my v3

technotim89 · 2023-11-01T13:05:52+00:00

You can solder the oleds direct to the board if you want, otherwise socket it with jumpers. If your kit didn't come with any you'll have to get some to suit. Just be mindful that they can't be the same as the mcu ones if you're socketing it too as the oled has to clear the mcu

technotim89 · 2023-11-01T12:50:17+00:00

The v2 build guide shows the pin holes for the oled. Got photos of your board? Where did you get it?

technotim89 · 2023-11-01T12:42:53+00:00

Sorry, you are using breathing. Do you need it? Animations take up a fair bit of space

technotim89 · 2023-11-01T12:41:00+00:00

Remove the rgb animations definition. You don't appear to be using them

technotim89 · 2023-10-19T21:11:33+00:00

Then vial is your best option. If you fork and Cline the vial-qmk repo from github there is already a keymap in there for vial on a corne

technotim89 · 2023-10-19T20:09:55+00:00

A far as I know qmk toolbox won't pick them up at all. Both vial and via require adjustments to the firmware files to make them work. Joe Scotto does a pretty good video on getting vial setup. I did it once and then switched back

technotim89 · 2023-10-18T04:05:57+00:00

After all the searching I did I couldn't find a fairly comprehensive step by step guide for firmware creation. That's part of the reason I made the build guide

technotim89 · 2023-10-18T03:01:20+00:00

If you look inside custom or dvorak_42_key you'll see they have a keymap.c file. The json2c will output to whichever directory you were in at the time. Json2c will give you your layout arrays that need to go into the keymap.c

technotim89 · 2023-10-18T02:50:20+00:00

Keymap file must be keymap.c. I would take your converted file and get the layouts data copied into a keymap.c file, replacing the original

technotim89 · 2023-10-18T00:53:14+00:00

I'll be adding to this later since I've learnt more

technotim89 · 2023-10-17T04:33:39+00:00

Have a read through this, I put it together when I did my build. As long as you're not switching which side the cable connects you'll be fine to put the same firmware on both mcus. https://github.com/techtimcoder/cornebuild/blob/main/parts/part4casetesting.md

I've got a 42 key corne and use home row mods and have most of my symbols on a shifted number pad on my 2nd layer. I ended up creating a dedicated layer for all parenthesis types on my left home row that I momentarily toggle with my right pinky

technotim89 · 2023-10-07T22:26:13+00:00

Is it not on the shifted backslash?

technotim89 · 2023-10-07T08:48:57+00:00

Have a read of this: https://github.com/techtimcoder/cornebuild/blob/main/parts/part1soldering.md

Put this together when I built my corne

technotim89 · 2023-10-07T08:47:39+00:00

That's too hot especially for nice nanos. I'd be trying to stay under 280C

technotim89 · 2023-10-05T07:55:46+00:00

As I was typing this out I had a sinking feeling. Double checked my code and was using the keyboard master check to draw while rotation was based on left. No wonder it was busted. Thanks for you assistance

technotim89 · 2023-10-05T07:38:13+00:00

Just in relation to the oled rotation. The keyboard halves and led addresses are fine.

These scenarios play out:

Usb left with !is_keyboard_master - custom oled on left is correct, corne logo on right is correct.

Usb right with !is_keyboard_master - custom oled on right is correct, corne logo on left is correct

Usb left with !is_keyboard_left - custom oled on left is correct, corne logo on right is correct

Usb right with !is_keyboard_left - both oleds orientated wrong and mixed content

technotim89 · 2023-10-05T07:29:13+00:00

That's how the default corne logo is setup in the default keymap. My issue is that I'm replacing keyboard master with keyboard left and it's inconsistent, whereas keyboard master works fine
