Hi, These are the 8 relays (K1-K8) that switch the power via their contacts. LSP3-LSP10 are the external connections for the switched AC power. But if you have difficulties in reading these easy schematics you shouldn't connect this circuit to the mains - you will become tiny, ugly and black if you ...

Hi,

Another solution would be to cut the connection to USB pin 1 (Vcc) and insert either a red SMD LED or two normal SMD diodes in series to drop the voltage from 5V down to about 3.5V - that's close enough to the 3.3V from the specs. I never had problems with the two-diodes-solution.

Hi,

some more facts about non-compliance.

Hi,

Some time ago I checked the USB polling rate depending on device descriptor parameters (for MIDI device): http://forums.obdev.at/viewtopic.php?f=8&t=1352&start=15#p9104

Hi ulao, My typical solution is to use an normally unused port pin that will be set on start of code and reset after completion. With an oscilloscope you can watch this port and e.g. the usb ports. -> http://forums.obdev.at/viewtopic.php?f=8&t=1352&start=15#p9040 Ciao, Martin

How many MIDI Event Packets can you send in one go? ... So I guess I have my answer, but I'd like to know where it's documented please! Hi winelight, You're right, two packets with a total of eight bytes is the maximum. USB MIDI transfers are defined as bulk transfers which are not allowed for low ...

Tytower, you are rude and ignorant. You come here, hijack a thread formerly marked as solved and claim that the project has to fit your needs.

Hi,
The Win7 issue and possible solutions were discussed earlier on "the other MIDI thread".

Anyway, I managed to get a 25 strip of 4313 so I'm ok now with 4K flash. I couldn't find these in EU so I had to order them from the States. According to their online catalog segor in Berlin has them on stock as DIP and SO: ATtiny4313-PU: 3.40€ (10+: 2.72€) ATtiny4313-SU: 3.60€ (10+: 2.88€, 37+:2.1...

Should i connect the int0 pin? If yes how should I connect this? usbconfig.h /* General Description: This file is an example configuration (with inline documentation) for the USB driver. It configures V-USB for USB D+ connected to Port D bit 2 (which is also hardware interrupt 0 on many devices) an...

It is always good to have some extra space. Try to use a chip with larger flash. It is quite common that you may like to add something in the future. You're right - BUT - when you want to use USBaspLoader located in the boot block you're limited to 2K boot block size on ATmega8, 88, 16, 168 even wi...

Hi,

Did you also connect INT0 pin?
