What is the longest amount of cycles V-USB disables the interrupts (for example because of running another interrupt on its own)?
Are the functions usbFunctionSetup, usbFunctionRead and/or usbFunctionWrite called from interrupts? I'm doing a lot of stuff in those functions...

In a project, Timer1 runs with 50 kHz (I cannot go lower for hardware reasons). The timer is used for PWM purposes and (via the overflow interrupts) also for a real time clock. I cannot use another timer for this clock. The real time clock works perfectly when USB is disconnected. If USB data is bei...

Hi, I know what you meant. It might work, but I don't want to just bloat the code. I'm unsure all the interrupt stuff I do would still be compatible. I'm looking for a clean solution.
The other thing... people of course wouldn't be forced to use it if they don't want to...

Hi, thanks. I don't plan on achieving higher transfer speeds. I just want to make sure USB works as it does with 20 MHz and I want to be able to make use of the extra speed %s in the rest of the project. The poor µC has to do a lot of stuff. I figure that it would also be possible to disable interru...

uhm, over 200 views and no answer?

Hi,

would V-USB work with an ATMega overclocked to 25 MHz? What changes would be necessary?

This sounds great. Now I only have to find out how to use it with TJvHidDeviceController..... hmmm...

But if I use GetFeature, no data (besides the report id) gets transferred to the µC, right?

Hi, I'm quite unexperienced with USB/HID in general so I need some help. Using HID is mandatory. On my µC I have a table full of data. It's pretty much as big as the eeprom is. The host software (written in Delphi using a TJvHidDeviceController component) needs to be able to update each line in this...
