Hey, It seems that you burned motor ic, Im almost sure that you connect motor when pcb was not stopped and gives voltage to motor. Thats why I told its was really stupid to disconnect it, you will not know when motor is powered and when not. Does drive making any sounds? (it can be really silent, just put ear on it and power on). Does drive says anything on terminal? Maybe something like this: Buzz Buzz Buzz if yes, it means that microprogram is trying to start motor but could not. Let me know. hm...... that's bad. But how did I do that?! It is really dissapointing cause I checked every connection twice but didn't get the right output in the terminal. Know I've damaged something. Data gone forever?! Greetz Jan
