Re: un1b0x - 2020 EUzebox BOM

Thanks Jubatian! I would prefer to get this build fixed up and running first or else I have wasted 2+ weeks but I think there is a good chance I will have to start over. I think I can see the crystal in your photos and it looks like it is only separated from the AVR by only one row of holes so I pre...

Re: un1b0x - 2020 EUzebox BOM

Hopefully Jubatian or CunningFellow will be able to tell me if I have to start over with this. I'd be interested to see how others who have made breadboard UBs have wired the crystal up. There are a few broadboard UBs shown on http://uzebox.org/wiki/Homemade_Uzeboxes_%26_derived_projects but it only...

Re: un1b0x - 2020 EUzebox BOM

No, I've been flashing the latest Bootloader5 as built from git. As for the instructions, I'm referring to how to use Atmel Studio to flash the bootloader, not avrdude. I think the way I tried is the only way you can do it under Atmel Studio, but it'd be nice to have some verification. I suspect I'm...

Re: un1b0x - 2020 EUzebox BOM

The instructions for flashing the bootlloader have a lot of room for improvement. They're not included in the BL github README (which gives a link to a forum post), they're Windows only and they're also incomplete. I was able to work out how to set the fuses but I'm not sure how you flash the bootlo...

Re: un1b0x - 2020 EUzebox BOM

In the last couple of days I realised I took a 'shortcut' that may not be valid when I was wiring up the crystal. The Euzebox schematic shows the following highlighted connections when wiring up the crystal: Screenshot from 2020-07-30 19-47-21.png I presumed that those connections were only required...

Re: un1b0x - 2020 EUzebox BOM

I've made quite a lot a progress in the last few days. I think I have wired up enough to be able to get a picture now but alas it did not work on my first attempt. That would've been beyond lucky! I have tested the TV with a PS2 but I have only tested the RCA/composite input. I have not tested the S...

Uze gone? Demo comps

Does Uze (Alec) not participate in this forum any more? I hope he's OK. I know about the UCC but has the UB ever been a target platform for a demo party comp? I know a lot of demo parties have 4K competitions but they're usually PC demos. The UB seems like a more appropriate platform for 4K demo com...

Re: un1b0x - 2020 EUzebox BOM

I've updated the BOM to 0.9.3. I needed to buy a file to remove some small plastic lips on the SCART connector to get it to glue properly and I also added super glue to list of required tools. My Arceli AVRISP mkii has arrived and I can confirm that it shows up in the tools dropdown of Atmel Studio ...

Re: un1b0x - 2020 EUzebox BOM

Yesterday I got avrdude to flash the bootloader without using -F and I was also successful in getting it to flash the fuse values, after soldering an unconnected wire and re-soldering a couple of other connections. It's still temperamental but I have to undo about 7 of the wires now anyway as they'r...

Re: Unibox - WIP 2020 EUzebox BOM

I have updated the BOM to 0.9.2 to list the ARCELI Atmel AT AVRISP mkii XPII AVR ISP mk2 USB AVRISP instead of 'any old AVR programmer' which are available new for £17 on Amazon and are sold as being compatible with AVR Studio. Isn't this the one you use artcfox? I'm presuming it will work fine with...
