User interface to initialise MCU
For instance AVRIODesigner ( is a nice tool frp doing this. It generates some setup code fro your µC. but as far as I know, it is currently no more...

controlling servo motor using Arduino Mega 2560 with AVR 5
Have you ever thought of using a SN74HC238N with teh outputs for 8 servos ? OC1A Output acts as the impulse-source which is fed into the 74238N. This is as 3-to-8-line-decoder....

Problem with TWI_vect
Okay, I will try again. The question was basically if libraries can have ISR-routines at first. My code is surely far away from being perfect or even working as desired.

Problem with TWI_vect
Okay, some parts of my question can be answered myself: 1. The error messages about int-return-type and reaching end of non-void function were stopped by including avr/interrupts....

Which µC is best for my new project ?
As far as I know, none of the chips has TWI-versions. I have to control ... : ... a chain of 3x AS5043 (magnetic encoder) ... 1x TMC428 (Stepper motor controller with 3 motors...

SPI-Problem (17-Bit packet)
Thank you for your quick reply. My first idea was to transmit 8-bits twice, maybe interrupt driven and then manually generate one more clock cycle on the SCK line. Is it possible...

variable cannot change its value
I am sorry, I posted just a template for the code situation, so the real variable names are different and more descriptive. Giving you compilable code is diffcicult, as the...

is there a XMEGA with integrated CAN-Controller available ?
I have projects with AT90CAN and with MCP2515 as well. AT90CAN has some advantages in my eyes over the MCP2515 as the AT90CAN has more CAN-Mailboxes and masks/filters. Also you...

variable cannot change its value
SRAM location is $0100 according to AS5, But inside theGetBackVar1-routine, a breakpoint moves from var1++ to the bracket line behind. maybe this indicates that the code has been...
