Re: Compiler problem Mega88 vs. 88P

Problem solved.
It was an AVRStudio problem which displayed usage of a newer avrgcc version than it used. Uninstalling and reinstalling the toolchain solved the problem.

Re: Compiler problem Mega88 vs. 88P

I just noticed, that with winavr20080610 it compiles allright.

The problem occurs with the latest winavr release.

Compiler problem Mega88 vs. 88P

Hi, I have just downloaded the latest V-USB drivers and built a little example for a Mega88. I compile the example using gcc in AVRStudio4. Everything works fine if I compile for the Atmega88. BUT: If I try to compile the same code for the Atmega88P (Pee!!!) I get a whole bunch of error messages: .....

Re: PCINT instead of INT0?

Hi Christian, thanks for the hint! I think we are getting closer. I did a simple test. I added the lines #ifdef SIG_PIN_CHANGE crash #endif to usbconfig.h and tried to compile. No error messages => SIG_PIN_CHANGE is undefined! Replacing SIG_PIN_CHANGE by SIG_INTERRUPT1 will cause a compiler crash as...

Re: PCINT instead of INT0?

Hi Christian, I have read the data sheet and written some test code. This is what it takes to enable a PCINT0 on a Mega88: sei(); PCICR=PCICR | (1 << PCIE0); PCMSK0=PCMSK0 | (1 << PCINT0); as compaared to enabling an INT0: sei(); EICRA=EICRA | ((1 << ISC00) | (1 << ISC01)); EIMSK=EIMSK | (1 << INT0)...

Re: PCINT instead of INT0?

Hi Christian, I have used the flooowing hook to check if the interrupt handler is called: #define USB_RX_USER_HOOK(data, len) PORTC=~PORTC; Is this the correct way to check? I have an LED connected to PORTC. With INT1 I see it toggeling a couple of times when I plug in the device. Using PCINT0 I see...

Re: PCINT instead of INT0?

Hi Christian, thank you very much for your hint. I could get it working on INT1 instead of INT0 on a Mega88. I am still having trouble using the PCINT0 instead. Here are my settings for PCINT0, which compile fine but refuse to work. Can somebody point me to my error, please? //commented values for I...

Re: PCINT instead of INT0?

Can somebody point me to an example project that uses a different interrupt than INT0, preferably a PCINT, please? I have spent a couple of days but I seem too stupit to change the interrupt from INT0 to INT1 or a PCINT. INT0 works fine, but any other interrupt does not work for me. Currently I am e...

can V-USB run on XMEGA MCUs

Does anybody know, if V-USB can run on the new XMEGA MCU family?
Has anybody tried?

Thanks, Tom

Question about HID_DATA / multiple feature reports

Hi,

I have been playing with HID_DATA which works great and I wonder if it is possible to implement more than one feature/ feature report in the AVR device.

If so, how would this look like?

Thanks, Tom

Re: How to output data to e.g. HID device

Ok, I finally figured it out to feed HID_DATA from Delphi.
The JvHidController component works great.
If anybody would like the Pascal code, contact me.

Linux Host Application for AVR-USB

Hi,

does anybody know of a Linux host application example for an AVR-USB using LibUSB, e.g. like powerswitch?

Thanks,

I'm still desperately searching for the reason why this happens. Can't anybody give a hint on a search strategy for the cause of the enumeration failure? What can be learned from the fact that enumeration works if the system is rebooted with the device plugged in, but not when un- and replugged? Tha...

Easylogger not enumerated on one computer

Hi, I have a problem with Easylogger on one specific computer: While the device works fine on most computers, it is not recognized/not enumerated on any of 8 USB outlets on one specific computer (WinXP like all other tested ones). All outlets work fine with other USB devices like a mouse. Strange th...

general AVR-USB timing questions

Hi, I have a few questions concerning the ObDev AVR-USB solution regarding computing capability: 1. How much AVR computing capacity is required if the device is in idle mode, i.e. no data transfered, just keeping the USB connection to the host alive? I suppose, the AVR gets USB work with every frame...
