1/10, 1/5 or 1/2 Micro-stepping and Non-micro-stepping
a. Host needs to send ‘M’ and followed by 1 byte value which indicates the stepping
mode to SD02B. Any values other than the given ones will be ignored by SD02B.
1 = no micro-stepping
2 = 1/2 micro-stepping
5 = 1/5 micro-stepping
10 = 1/10 micro-stepping
b. 1/10 micro-stepping means every step of the stepper motor is further divided into 10
micro-steps. For a stepper motor with 1.8°/step, 1 micro-step will rotate the motor
shaft 1.8° / 10 = 0.18° if 1/10 micro-stepping mode is chosen. It is goes the same for
1/5 and 1/2 micro-stepping. Non-micro-stepping mode will step the motor shaft at its
original value which is 1.8°.
Send this 8 bit value to SD02B to
choose the stepping mode.
