Sofirn SC21 mini

Well looky what showed up in the mail yesterday! I got one built up and tested, worked great. I’ll try to get some more built up over the weekend to be able to ship out.

Yay

I just got a new SC21 Pro today… I will be happy to use your new programmer and pogo pins, when ready.

the Programmer and pogo pins you provided for SP10 Pro also works on TS10. It has been working Great for me.

fwiw, the hex for SC21 Pro needs updating to lower lows, and to add LVP to the button light circuit…

in the meantime, would it work to use the TS10 hex you made, dated 7/19, on an SC21 Pro

the only difference I know, from using the TS10 hex, is the SC21 Pro button light will be Off when main LEDs are On… no harm in that. But there is a lot I dont know… lol

Any reason NOT to put TS10 firmware on SC21 Pro?

Jumping in the pool here without reading this whole thread. I’m interested in updating to Anduril 2, so I’m interested to hear the response to jonslider’s q in the previous post.

also, my programmer is rather different than ones I’ve seen used recently.

How can someone guide me to instructions how to use this programmer with the SC21 please?

I see no reason not to put TS10 firmware on the SC21 Pro. I’ll be the guinea pig and report back.

Sorry, sbslider. That’s a USBasp, great for the attiny85 and attiny1634. But not compatible with the attiny1616. You’d need a USB to Serial TTL adapter like what you linked to above. I’ve got some on hand that I can send out with pogo adapters, or they’re available on Amazon

step 1. buy the TS10 ProgoPogo from gchart
2. here is a tutorial:

word is avrdudess also works… I cant say… my Old Mac has a brain of its own

good luck,
for me learning to reflash without prior experience… was a total cluster. I killed 2 lights in the process (I call it a Seminar Fee), almost more than Ive killed modding… lol…

I dont have your background, it may be like frisbee golf in Alameda Park for you

Ok, thanks for the clarification. I’ll PM you regarding specifics of the programmer and adapter.

Confirmed: I just flashed the TS10 file to my SC21 Pro and it’s working great! Lower lows and all.

you Rock! thanks gchart! :beer:

Thanks for the link jon_slider, but for some reason it doesn’t work for me right now. If I copy the text of the link and go there it does work. Weird.

I’ll likely slow roll this one for now, sort of like my standard tee shot at hole 4 of Evergreen Park disc golf course.
No disc golf at Alameda park, too many folks hanging out there for that activity. Would be nice though, as that’s much closer to my house. Back to the topic, I think the thing Anduril 2 has that I would am most interested in is the timer feature in 5 minute increments for sunset, so for now I’ll watch this thread and see how things go for folks.

glad youre on a roll… :wink:

the link is too long, thanks for the heads up, glad you figured it out… edited my post so its not a raw link… this way works:

here is a tutorial:

I want to try my hand at first time flashing - so if I follow those instructions from the reddit post - with all those parts, it should work for the SC21? I am a complete newb at this but willing to learn.

yes and no

yes the programmer for the SP10 works on the SC21, but the pogo pins are different

this is what the SP10 setup looks like:
.

on the SC21 Pro, there are 6 flashing pads, on the SP10 Pro there are 3 flashing pads

gchart built a Pogo Pin Adapter for SC21, that looks like this:
.
so the pogo pins can reach flashing pads number 2, 6, and 1 on the SC21 Pro

you can also solder the wires to the SC21 Pro flashing pads, if you dont have pogo pins

Ok I see. And I’m guessing since you can’t buy a setup that’s off the shelf, you either have to DIY it or get one from gchart.

Assuming I want to build one from scratch, what components would I need?

Here’s the board: OSH Park ~

Same components and instructions as this: OSH Park ~

Very cool, I’ve got some homework to do

Which Hex file are you using for the TS10?

http://www.ghart.com/blf/firmware/hex_files/sofirn_anduril2/

choose: anduril.2022-07-19.wurkkos-ts10.hex

Thanks Jon!

Hmm, getting “Network Error” trying to download it. I can access the page, and see the files, but download is failing. The site certificate expired on 9/5/22, wonder if that’s the problem.

please try again, I edited my post, dont use the link you quoted

Same error.
