Hi, excuse me for not writing in German. I can read German, but my German writing is awful. I am a newbie in atmega programming. I have a atmega32u2 hardware setup which needs an internal clock running at 8 MHz. It means I can not use DFU, but have to use TeensyHID, which has been part of LUFA (here: http://www.fourwalledcubicle.com/files/MyUSB/LUFA%...). This setup however is meant for ATMEGA32U4 (Teensy 2.0) with 16 MHz external oscillator. My question is what settings I should have in the makefile for my atmega32u2 and also what fuse and lockbits settings I need. By the way I have attached the complete source and visual studio project file package for building the teensyHID for the related and PIN compatible at90usb162 MCU related to the board I am using. I hope someone can help me. Thanks in advance!
