powerstep01 spi baudrate setting problem

Posted on March 09, 2018 at 14:05

Hello,

we tried to communicate to the powerstep01 trough spi and with a baudrate of 500kHz everythink works fine.

The problem occur if we set the baudrate above 500kHz. Then we lose the first bit of each byte.

For example:

- send 0xFF to the powerstep01 ABS_POS and we receive as result 0x7F

- send 0x1FF to the powerstep01 ABS_POS and we receive as result 0x17F

In the manual description is a max Value of 5MHz defined.

Somebody help me if i overlooked something or there have to be specific timing issues.
