Fuses are not like dice you dont just toss them up and see what you get? You need to know what you want and set accordingly. You could lock yourself out of the chip up if you set the wrong fuse. For example what clock do you want? Is it going to be internal or external? Here is a good calculator m h...

Have you put the usbconfig.c in the make? Can you show us your make file.

eh, I figure I'd try. Oh well. He is gone for now.

Tytower, you are rude and ignorant. My thoughts exactly. You continue to misunderstand peoples candor for arguments. You continue to to argue and insult while ignoring the responses you are given. You have shown all of us you dont care to read ( if the rules are not clear enough ) and you make no a...

This is exactly why I tell everyone not to start off on the silly Arduino boards. Learn the right way first Ok make file 101. go to project->config settings in the general section check use external makefile, brows to it. Make sure your makefile is configured, there are hundreds of info's out there....

Is this forum still being used? Yes Has this problem been solved? Second to last post is quite clear. Anyone know whats going on? As to the problem, years its pretty clear to most of us now. Though its not just one issue. These Confirmation codes will drive everybody away they are a pain in the ars...

I can not say for sure if 8mhz will work, have to check the docs on that but the setting for speed is in your make file. If you don't have a make file it depends on the IDE you have.

"Which Atari keyboard?" it just occurred to me you are talking the ST(e) "keyboard" for some reason I was thinking the key pad. Big difference, my fault. My adapter is for the console atari's.

horo, I dont see where the OP was talking about the bootloader code size? Though this is a good point to make, bigger chips will not change that. If you need a chip with a lot of flash get the atmeg328. I use this with my v-usb project and I still have not used it up. my adapter support every contro...

using a voltage divider limits the pull-up voltage only. Signal levels generated by the processor wont get touched. The signal levels need to be near the right levels. See the USB spec.

Using bulk out you can separate the packed. 1.0 standards does not allow more then 8 at once. Use bulk you can try this while (!usbInterruptIsReady()){usbPoll(); } usbSetInterrupt((void *)&reportBuffer + 0, 8); while (!usbInterruptIsReady()){usbPoll(); } usbSetInterrupt((void *)&reportBuffer...

I can't tell exactly what your setup is without seeing the entire schematic but: " I'm not quite sure what to do with the 1.5K pull-up" -- Yes you need it, yes it goes on the d-. Releasing this drops the USB. " Should the 68 ohm series resistors go on the SH or the SL side, if they ar...

yes, search for the popular midi controller here for an example.

I wont get in to the ohms law of it all here but I will tell you this. atmega8/88/128/328 all have to have a "perfect" voltage. For example the 128/328 will not work with anything but 1/2 watt diodes. So my advice is try it correctly first, then play with it.

Maybe I'm not understanding you right here but the in endpoint is used like so.



This is using an in interrupt method.
