i'm using avr studio.
i've included both 3pi.h and orangutan.h.
when i try to print to the screen i only get black blocks.
and when i try to call set_motors(), or set_m1/m2_speed, only it's left motor turns on and it goes in circles. i'm trying to get output from a ping sensor, i can't even get as far as to debug it. what am i doing wrong?
