| | | Thanks for your help :-D Just so I'm clear, ref pink book page 10-17. Does the "bit_set( 0x1021, 1 );" refer to bit 0 -EDG3B, and bit_clear( 0x1021, 2 ); " refer to bit 1 -EDG3A. This is what was throwing me, I always thought bits started at zero (...) (25 years ago, 16-Mar-00, to lugnet.robotics.handyboard)

| | | | (...) No, that's a very good question. It had me confused, too. The second argument to bit_set and bit_clear is not actually the index of a bit at all; it's a bit mask. For example, when you do bit_set( 0x1021, 3 ), the 3 becomes 0000 0011 in (...) (25 years ago, 16-Mar-00, to lugnet.robotics.handyboard)

| | | | Hi I'm using the L297/L298 chip configuration to run 4-phase unipolar stepper motors. Currently I'm driving them in half-step mode but I'm not getting enough torque.. :( Has anyone successfully gotten the L297 chip into wave drive mode? I believe I (...)
