Re: IgorPlug-USB (AVR) USB IR receiver

I live in Germany, where the Tiny2313 costs less than half a glass of beer ;-)

Re: IgorPlug-USB (AVR) USB IR receiver

Hi Cb900f, the Tiny2313 is a very basic device, and I guess that it was selected because it's cheap. Most likely there is a way to port the code to some other device, but unfortunately the IgorPlug-USB page is so poorly structured that I gave up searching for the source code after a couple of minute...

Hi Alan I2C-tiny-USB uses the control endpoint to transfer data, therefore it's limited to 8 Bytes at a time. If you plan to transfer more than 8 bytes at a time you need to implement an interrupt endpoint in your USB device. It may be a good idea to take USBasp or USBaspLoader as a starting point. ...

Hello Andrew You asked a number of questions... Will the UART interrupts interfere with the USB communication? - Yes, it will. The USB code must not be interrupted. How would you recommend that I get started? - If synchronizing your devices with the USB 1msec "heartbeat" is an option, you ...

Hi Bearing

To my knowledge (as a Debian/Ubuntu/OpenWRT user) there is no issue with AVR-USB other than bulk transfer from low speed devices (e.g. CDC).

What you describe sounds more like an electrical problem (i.e. zener diodes).

Hi epsilon_da

what do you mean with "minimalistic code"? Could it be that you never opened the folder usbdrv?

Andy, I don't expect a problem with the 16MHz code. Did you test the crystal oscillator's frequency stability of the device that doesn't work? Hint: if you don't have a precision counter, try beat counting. Create a fixed frequency output signal from the device in question and compare it with one fr...

Using a Tiny2313 should be possible. However, keep in mind that there are just a few hundred bytes left for your application,

As always "Powerswitch" is a good staring point.

@guest: how much do you pay for a atmega8, at which quantities?

Sorry, but I didn't try USB-LED-Fader under WinXP, and currently I don't even have a WinXP installation for testing,

If you're looking for libusb, it's included in the powerSwitch archive.

AVR-USB is "least-cost low-speed USB". No bad feelings, but I'd recommend that you look somewhere else.

You'd need a rather fast chip, and "abuse" it for software-only USB protocol. To my knowledge, µCs fast enough for your this task (~ 100MHz) a) have both a cache and a pipeline, so fixed timing for "bit-banging" low level protocolls is (at least) difficult to implement, and b) of...

I tested HIDBoot with a different WinXP installation, and this time it worked. A closer examination of the first PC showed a badly broken USB enumeration (even attaching a USB 1.1 hub requires a manual driver installation).

Sorry for having bothered you for nothing!
