寄存器写入顺序是否可能改变寄存器的行为？

你好。我玩eval board + steval来设置我的步进电机参数。它完美无瑕。现在我正在编写Arduino代码以获得相同的控件。寄存器映射已复制电机参数。 SPI例程正常并经过验证。


与Arduino一样奇怪：我可以将电机“移动”与steval，读/写寄存器（它们与使用Steval和相关软件相同）相同，但电机运行SLOWER。
始终比设定的速度值大约80％。
有了Steval，好的。使用Arduino，一点点啸叫声和80％的速度......速度寄存器（与所有其他寄存器一样）是相同的。
使用Steval，电机档位以2500step / s的速度运行，使用相同的控制，但使用Arduino时，它的档位为900step / s。

它设定为1/128微步，Ke已经确定了。令我更困惑的是寄存器的内容是相同的！
有任何想法吗？

寄存器写入顺序是否可能改变寄存器的行为？
有人引擎反转Steval打开时执行的设置吗？

先谢谢你

Hi. I played with the eval board+steval to set my step motor parameters. It works flawlessly. Now I'm writing Arduino code to get the same control. Motor parameters have been copied by the Register Map. SPI routines are ok and verified.


Strange thing with Arduino: I can move the motor ''almost the same'' as with the steval, read/write registers (they are the same as using Steval and the associated software) but the motor runs SLOWER.
Always around 80% than the set speed value.  
With Steval, OK. With Arduino, a little whistling noise and 80% the speed... The speed register (as all other registers) is the same.
Using Steval the motor stalls running around 2500step/s, using the same controls but with Arduino it stalls at 900step/s.

It is set for 1/128 microsteps, Ke has been determined sperimentally. What puzzles me more is the fact that the registers' content is the same!
Any ideas?  

Is it possible that the register writing order changes the register's behaviour?  
Has somebody engine-reversed the settings performed by Steval when it is turned on?  

Thank you in advance
