Scratch that question, the JPG you linked to contains everything I wanted to know, including that port F's A2D converters are free...

Hmm. 6 axis IMU on CM5 anyone?

Have you mapped the port uses of the CM5? it's something I intended to do but haven't got to yet...

Hello,

i found the error. the pull-up resistor was not set for port E

Code:: DDRE = 0; //set port E to input direction PORTE |= _BV(PE4); //enable pull-up resistor 4 EIMSK |= _BV(INT4); //enable interrupt 4

Hello,

how do i get the state of the buttons(up,down,...) in C (avr-gcc)?

The "Up"-Button is connected to the external-interrupt 4 as you can see her:

i use a interrupt-routine to catch the keypress-signal.

Code:: SIGNAL (SIG_INTERRUPT4) //INT4 when Up-Key pressed { PORTC &= ~_BV(PC3); //turns AUX-LED on }

has anyone a working code-snippet?

Bye
Lenny
