Digispark Project Ideas / !!! PAYING JOB !!! Digispark and scrolling OLED display
« Last post by jamessauter on February 26, 2017, 01:30:00 pm »
I'd like to pay someone to do some (what I think should be simple) work for me.
I honestly don't have the time to learn how to code, nor the attention span.

I here is what I want.
I want to use a Digispark, to scroll a message/image across a color 128x36 OLED screen in a loop.
I also want to know if a single Digispark can run this scrolling message on (4) of these OLED screens at the same time??

Here is a link to the screen I want to use https://www.crystalfontz.com/product/cfal12836a0088-128x36-small-oled-display
Here is a video of that I want the screen to display https://www.youtube.com/watch?v=GUv8IZCOMys

I can get, or create the pixel art to scroll if needed.

I live in Florida and am glad to pay someone a reasonable amount to get this working for me. I will need the full code, and a very basic lesson on how to copy the code to additional Digisparks later.

Feel free to txt me, It's the easiest way to get me. If you want to call, please text me 1st, I don't answer unknown numbers.

Thanks, James  -  239-410-1622

Digispark (Original) Support / DigiKeyboard not recognized on Linux boot
« Last post by SHadowX on February 26, 2017, 08:24:18 am »
From a certain kernel version onward, the Digispark(rev2) running as a DigiKeyboard is not correctly recognized at boot:
Code: [Select]
kernel: usb 9-5: device descriptor read/64, error -62
kernel: usb 9-5: device descriptor read/64, error -62
kernel: usb 9-5: new low-speed USB device number 4 using ohci-pci

kernel: usb 9-5: new low-speed USB device number 6 using ohci-pci
kernel: usb 9-5: device not accepting address 6, error -62

But when I physically re-plug it after the boot has finished it is correctly recognized:

Does anyone have an idea as to how could this be fixed?

Digispark (Original) Support / Re: Digispark and USB power without data pins
« Last post by rnsi on February 25, 2017, 05:45:40 pm »
Update:

I uploaded Start (blink) and it works with all power sources. So back to my code, it's hanging on DigiKeyboard.sendKeyStroke(0);.

So can DigiKeyboard be used without USB? If so, how?

Thanks

Digispark (Original) Support / Digispark and USB power without data pins
« Last post by rnsi on February 25, 2017, 10:48:33 am »
If I plug the Digispark into a USB port, it works. But if I connect a battery to the USB connector, it lights up but doesn't run. I tried this with coin cells, a USB battery pack, and a USB wall outlet. I also covered the two center data contacts on the Digispark with electrical tape and when plugged into a USB port it lights up but again doesn't run.

So it looks like I can only power the Digispark through the USB connector if USB data is also connected. Is that right? Is there a way to power through the USB connector without using the data pins?

Oak Support / Re: Original Oak from kickstarter, can't get hit to update

To create a tutorial, simply (!!) go to the wiki page, log in (top right) using your forum credentials, and then edit the main page using the pencil on the right side, and add a link to for a new page. Once you've made it, it should show up in red (IIRC), and will take you to a page that says the pages doesn't exist yet, and asks if you want to create it. You'll then be able to edit that page and start putting the tutorial together.

OK good luck. Either mod a controller board to bring out the buttons... or build your own board with a 4021N IC using the schematics. I think the pullups resistors are 4.7k on the buttons.

If you make your own board, you'll just need to figure out the pinout of the controller port on the mini.

You want to put the mini inside of a arcade style enclosure and bring out the arcade style buttons.

you got it!

but anywho

no i dont want any other controllers besides the arcade buttons and stick

as for the NES converter i cant find much to any documentation for a nunchuck port that seemed useful... but i did find a classic nes to nes mini converter...


edit: seems what ill have to do is:

Looked at your post again... Do you need to have the NES converter (pic 2) in this chain? Is it because you want to use optional controllers?
