Braids THT in KOSMO format

KOSMO MODULES

The hardest part for me was getting the programmer (STMCubeProgrammer) to run, but it is easier on windows, I think!
I will make a small tutorial soon and upload the hex files to my GitHub! :slight_smile:

Hi Sebastian,

It now works but I still have a few issues with the display, I guess I need to reflow the joints. I couldn’t get cube to work so used stlink. Where can I download the renaissance firmware from or can you send it to me?

Thanks

Good to hear! Yeah, I also had issues with the display on one unit. Don’t forget to also check the pins that connect the two pcbs, I think that was one issue here :wink:
I made a new release with the hex files, including the modified renaissance firmware:

What exactly is the stlink software you used? I would love a simple method for programming my bluepills!!

nothing personal , I’ve just been to busy / lazy to take the time and figure it out .
honestly I haven’t done much building / playing in a month sense moving everything to the basement it took way longer than I thought so its just break from everything time .

Looks good! Where did you source the display from?

Mouser, but I think I bought all they had in stock. That was 8, enough for 4 braids. Buying 10 would have been cheaper, but they didn’t have 10.

I assume you mean blue pill. I am using this one:

Just make sure you don’t connect that odd 5v pin that was ground in the original blue pill.

Soundforce (original creator of the tht braids ) suggests this

https://m.de.aliexpress.com/item/32525208361.html?gatewayAdapt=gloPc2deuMsite&spm=a2g0o.productlist.0.0.1ec58ef4O3eQK1&algo_pvid=e1da27a1-182d-4bad-a749-4baf57f30e00&algo_expid=e1da27a1-182d-4bad-a749-4baf57f30e00-0&btsid=0b0a187b16097043665486727e2683&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_

But there is a change in pins, the top right pin was ground before and is 5V now, so make sure you cut that leg, otherwise you got yourself a short :slight_smile:

oh i see, thanks, is it the 128kb one? i read thats important for whatever reason?

They said it is, on the other hand the listing says “64k” in multiple places and not “128k”.
