Satan GH60

[sonwalker]

I mean when reflash the file,  my keyboard doesnt accept the new one.  I dont know why,  2 weeks ago its still work for me,  but now i cant change the layer again with tkg tool kit and eep file download from tkg website,  even though i finish all the step correctly

[nathanrosspowell]

Just got a Satan in the post. Damn white PCBs look good. Just waiting on some switches any day then I will get it all set up and give report back on how the flashing goes! Plan is ISO with all the split keys.

[tofgerl]

I am without stabilizers, but am still trying to put together a Satan board right now. I'll remove some switches if necessary to install the stabs, I just wanted to be able to test the firmware.

The firmware is clearly TMK, and indeed when you first plug it in it works just fine, but has neither an FN key or any advanced features - just basic 60%. In fact you can't even get the F-keys!

Using software found here I've been able to dump and reflash firmware, or at least it appears to work.

Using a fork of TMK found here, made by the same github user, I've been able to compile a hex file which the other software appears to approve of and flash.

However, the keymap is the same afterwards! Even if I try an azerty keymap there's no change.

That's how it stood last night when I went to bed. Will continue testing tonight. I don't need many changes, but an fn layer is kind of important :|

Also, I ordered through Bhiner. Went off without a hitch, and their 50% DHL rebate was very handy. Cost me just over 22 USD to ship to Norway, and it took something like 4 days after paying on a weekend, most of which was apparently spent waiting for something to happen. As soon as DHL had it updates started coming in several times a day, and I had it within 36 hours.
Boards were 31 USD each, and I'm happy to say Bhiner is so happy to cheat the customs services that they have a specific field for it on their ordering form

I've used Kai Ryu's TMK fork on the RS60 I had before, and ran into the same problem (keymap wouldn't change if the firmware is updated). Looking at the sources, I realised that he's storing the current keymap in EEPROM, so even if you update the actual firmware, the keymap stays as it was before (because EEPROM is not normally updated along with the firmware). The solution I found (which worked for me) was to use the bootmagic key combo at power up that clears eeprom (it should be space+backspace by default).

I apology for the lack of document on my fork. You can find my comment about this feature here: https://github.com/tmk/tmk_keyboard/pull/113#issuecomment-48425977
But this time I think it's not my bad

I didn't mean to imply that there's any problem with your work - it was just a bit unexpected It might be good in the long run to main some kind of "changelog" to explain the changes from the standard TMK, to make it easier for the people coming from there Nice work, by the way

That's probably it. I set that variable and copied those functions from a blog, believing that it was in order to enable REVCHN-support. But I guess it's optional, so I'll try it without the variable set and see what happens.
I'll try TKG as well, but first I need some sleep - it's very much friday afternoon, and I've had a hell of a week

[tofgerl]

Yep, clearing EEPROM was the trick. I'll try to write up a quick little guide with what you need to do, it should be about 6 steps not including installing all the dependencies for compiling TMK or writing your own keymap, which is covered elsewhere.

It would be appreciated  I'm sat waiting on stabs to arrive so I've done nothing more with my PCB than power it up and test it works.

Here's my tiny guide:

Note that I might have forgotten a step or two, so let me know and I'll update the guide as needed.

[tofgerl]

Holy crap, it's been almost two months!

Well, I've now used this PCB for a few weeks, after finally getting all the parts and building two keyboards. The third is in the wings, I just need more stabilizers.
Quick verdict: Absolutely no reason to not get this. The only thing it doesn't have is good documentation and support for RGB LEDs, and both things are for newbs

I quickly disabled the 'store keymap in EEPROM' thing, as it was tedious to first flash the keymap, then clear EEPROM, then test the keymap, then repeat. I might make a quick zipfile with the changes I made in Makefile and config.h. The additions to your keymap is no longer needed without the EEPROM thing.

Anyway, if people ask me to, I will update my gist to remove the EEPROM thing, thus making the process a little simpler. But this thread has died, so for all I know I'm the only person who will ever use this PCB

I'd appreciate the udpate 

Glad to hear the pcb has worked out well for you. I'm still waiting on my stabilizers... seems like only people who hate themselves decied to use 7u pcb mount stabs 

[jdcarpe]

One day I will build my Satan board.

[Aqoush]

Good to hear about the Satan GH60 -- I've ordered 2 of these and will be trying them out by the end of January hopefully. Seems like it was a bit of work to figure out how to get custom keymappings. I'll test out your guide and return feedback soon 

[Connly33]

I have one on the way for my first build, it should be here in about a week, so i'm glad there are a few of these threads talking about the satan GH60. I was going to go with a Sprit 60% for $60 but they sold out right before i had the money, so i got one of these on ebay from a vietnamese seller for $43. Along with stabilizers.  I'm a complete newb when it comes to firmware and programming layout's so i'm glad there are a few guides out there.

[Toggi3]

OK.  So.

I got one of these boards and have it assembled, it works fine, except one thing that gives me pause is I can't use dfu-programmer to dump the GH60's original firmware.  This is using my laptop with Ubuntu 15.04.

Code: [Select]

jeffj@jeffj-MacBookPro:~$ sudo dfu-programmer atmega32u4 dump
Failed to read 28672 bytes from device.
jeffj@jeffj-MacBookPro:~$ sudo dfu-programmer atmega32u4 dump-eeprom
Failed to read 1024 bytes from device.

Interestingly, I can get other info using dfu-programmer and issue a reset/start.

Code: [Select]

jeffj@jeffj-MacBookPro:~$ sudo dfu-programmer atmega32u4 get family
Family Code: 0x1e (30)
jeffj@jeffj-MacBookPro:~$ sudo dfu-programmer atmega32u4 get product-name
Product Name: 0x95 (149)
jeffj@jeffj-MacBookPro:~$ sudo dfu-programmer atmega32u4 get bootloader-version
Bootloader Version: 0x00 (0)

any ideas?

[Toggi3]

Got impatient, went ahead and flashed using to***erl's tutorial, it surprisingly worked but I can't erase EEPROM in linux using the windows util.bat obviously.  dfu-programmer still has no idea how to dump or flash anything, so I am left hanging in terms of how to erase the EEPROM.

Code: [Select]

root@jeffj-MacBookPro:~# dfu-programmer atmega32u4 flash-eeprom empty.eep
Error while programming eeprom.


Code: [Select]

OK, I figured out what I was doing.  Here is my simplified guide for how to reprogram the GH60-RevCHN (AKA the GH60 'Satan Intention to do').

It is quite simple really.  Go to the TKG keymap generator, http://www.enjoyclick.org/tkg/ input the raw data of your layers from the keyboard layout editor tool, download your keymap.eep for the RevCHN, download Kai's tkg-toolkit, do setup.sh accordingly, then do "./reflash.sh keymap.eep" in the 'linux' folder...  Done.

I cant wait untill the PCB gets here so i can put it together and play around with the keymapping. This makes it seem a lot more simple and , well doable for someone like me that doesnt have much experience with keyboard firmware.

That looks pretty good. It's making me regret not getting LED's initially, i can always get some later and add them then though.

Cool post, these can be some of the easier 60% pcbs to get a hold of at times, so its nice to know they are actually pretty good!

[nathanrosspowell]

Using TKG toolkit I cannot seem to reflash the board. Pressing the button on the PCB when running reflash seems to turn off the board, but the script doesn't seem to connect to it     Anyone had this experience?


EDIT: for whatever reason, the button on the pcb didn't seem to work properly but the 'magic' button and 'pause' managed to bump it correctly into bootloader I now have a nice split backspace ISO keyboard set up in Canadian Multilingual

Me. For some reason it worked with the backside button for a good two weeks then it suddenly stopped.

What's the magic button? Both shifts?

[tofgerl]

Ironically I could never get the magic button to work, but the little hardware-button works fine. *shrug*

Oh, and I should REALLY update that gist. Think I'll do that now...

[nathanrosspowell]

Yep, both shifts and pause (which is in the function layer) did it for me... Funnily enough, I flashed a layout which didn't have the pause key on it, but the PCB button started to work after that :/

Tofgerl: the steps for deleting 'tmk_core*' folders, I think you just need to do 'git submodule update'.

Yea, that makes sense. Some of the links are broken too (as I'm sure you noticed).

Just want to say thanks for taking the time to make the walk through in the first place! I was in a position where I had re-installed my OS, so even though I've flashed some pcbs before, I had to start from scratch and your guide was priceless.

I had good luck programming the KC60 keyboard (purchased from Massdrop). Is it possible to get the KC60 PCB as a separate item?

[HPE1000]

Are these pcbs pretty reliable? I just need a pcb to replace my broken poker 2 pcb and I don't care for programmability.

Fixed URLs and made some small corrections. I'm going to run through the entire process as if I was following the tutorial later tonight just to doublecheck, but it should be OK now. I might be missing some editing, though - I feel like I edited at least SOME files...

Thank you for your commitment to this specific PCB. If you werent doing this, I would have a much more difficult time

I don't think so, it only comes pre-assembled from massdrop. You might have to do what I did, which is buy a KC60 and harvest the pcb for yourself

What a weird colour for a PCB.  I thought using the "SATAN" theme at least the pcb would be done in total Black with a metal plate in Red.

You're confusing me with the usage of "white" when I know all Satan worshipers love Black and Red  ;)   .

[tofgerl]

That's not exclusive to Satan-worshippers.

[merlin64]

The color doesn't matter, what really matters is that it depends on what your intention to do is.

Thought that would be self evident, summon the Dark One before you once this keyboard is made  .

[tofgerl]

The work on the revised guide has been slightly delayed by the fact that I don't actually have a Satan board at home right now. I broke one, one is at work, and the third lacks stabilizers, so it's not yet been built.

Howd you break the one??
