I'm new to pic programming and would welcome some help in a programming a pic 16c84 to drive a stepper motor. (with additional output circuit) I plan to use portb and need the following output sequence 1001 1100 0110 0011 I need this sequence repeated 350 times to give me a total of 350 x 4 = 1400 steps. Then the sequence has to be reversed to drive the motor for the same number of steps in the opposite direction. This circuit is for durability testing of a stepper driven flap. I have some ideas for the programming but the urgency of getting it working does not allow me to experiment. Thanks. Gary gary.walker2@virgin.net
