Hi Everyone

My purpose is only detecting HID device in windows and read and write EEPROM.I want to use ATtiny45.
For this reason i start to remove some functionality of Automator to recduce hex file to be suitable for ATtiny45.
I remove following functions:

setOutput
getInput
getOutput
getStopkey
beep
UTIL_INTERRUPT
toggleLed
setLed
setRelayEnable

Also i comment " if ( TIFR & ... until pollAdc() " in the main() and change USB_CFG_IOPORTNAME to B because ATtiny45 has not PortD.
Also i change atmega8 to attiny45 in MakeFile.

With above changes it works still properly for Atmega8 and i can read and write EEPROM from a simple VC application but for ATtiny45 it does not recognize by windows as a HID device! I test some fuse bits also but problem still remain.

Has anyone any idea to solve this problem?

Regards

Please have a look at projects based on the ATTiny45, such as i2c-tiny-usb or AVR-CDC.

Hi Everyone

Thanks a lot.I solved the problem with new version of winavr.Now I want to send an address to tiny45 and read a byte of eeprom.I found eeprom_read_block in firmware and i can get all 256 byte of eeprom with HidD_GetFeature() api but i can't send an address and get only one byte!
Is there any idea about it?

Thanks a lot
