An arm cortex-M0 MCU is adopted to drive the powetstep01.
The initialization of SPI is done including CS, SDO, SDI, CK,BUSY, STBY.
Here is the problem, I want the step motor run, so I write this:
SPI1_TX0 = param;//param=0xFF50, since the address of the run command is 0101000DIR, and FF represents speed
SPI1_CNTRL |= GO_BUSY;//start the transmit
The powerstep01 did not work. Is this the right way?
Or what else should be done before sending commands(SPI has been initialized already)?
Thank you very much!
