Btw, do you still have CPU and flash left for a music track? I'v been doing some fiddling on a simple pattern/phrase based replayer that should cut the data size by half or more. If so, what's the flash budget you'd have for a song, patches and sound fxs? Heaps of CPU left. I have not taken the inl...

Works here too! With Micro SD card, there's some bit of thrash on the left side of the picture (I see it too in your video). But with a regular Kingston SD card, it's flawless. Pretty cool to know it's streaming from the card. :) I have worked out the trash on the left side if the screen now. I was...

Worked out the difference between the real SD card and the emulator. After getting a CMD12 (stop transmission) the real SD card goes busy for a bit. You have to wait a while and then send two more 0xFF bytes to it before you can send a Read Multi command. The emulator you can send CMD12 and then the...

OK - got the sync timing sorted. so the picture is stable. The worked out that there is something different between the emulator and a real SD card with the "stop transmission" command. Have not worked it out yet, but I have discovered if you send two "stop" commands in a row it ...

I've been doing some spreadsheets. Can Uze/Harty please give me advice on how popular these kinds of things are. PM me if you don't want to make sales numbers public. I am going to set the kickstarter campaign "success" level at 10 units. If I sell them for $50..$55 dollars then I will be ...

Yeah - they would have to be assembled. A lot of people would have a hard time soldering it themselves. Also I would have to CNC the cut outs for the uSD and the other stuff. People would not have fun doing that themselves and getting it neat. The only thing people would have to do themselves is sol...

Wow, this looks great! This really gets me in the mood to create a design on my own. Did you design the packages for the buttons yourself or did you find a library for them? Thanks. I cheated. I actually used a 1612 resistor as the footprint, and the button is drawn on the copper layer. For sending...

Finally have myself a real uzebox

bit of excitement to start with the picture was all purple. Did some continuity testing, checked the signals on a scope. Then realised "AH port c - JTAG"

16 colours is easy.

You get to use the SWAP instruction.

6Bpp is hard. The quickest way is a 768 (12x64) jump table if you don't have enough clocks to spare for shifts.

good work
