没有找到最大的QEI率

亲爱的LubinI正在尝试使用一个QEI块来捕获一个直流电机的角度位置，编码器提供一个非常高的脉冲数（每转500个），它与齿轮相耦合，降低了速度（84倍），这意味着对于一个最终轴的旋转，我有500×84脉冲。ES），使用具有16位输出的DSIC33 FJ128MC802 QEI，在我得到一个转弯之前溢出。我正在考虑使用QEI中断来捕获溢出，这样我就可以更新脉冲的总数，这将是可能的，使用外部C代码块，如果可以的话，你能给我一个如何做的提示吗？

    Dear Lubin
I am trying to use a QEI block to capture the angular position of a dc motor with an encoder that delivers a very high number of pulses (500 per revolution) it is coupled with gear that reduces the speed (84 times) this means that for one revolution of the final axle I have (500 x 84 pulses), using the dspic33fj128mc802 qei with a 16 bit output this overflows before I get one turn. I am thinking of using the qei interrupt to capture the overflow so that I can update the total number of pulses, would that be possible using the external c code block, if so could you give me a hint of how to do it.
thanks in advance

你好，Bizard，在QEI块GUI中应该有“索引计数器（完成旋转数）”的输出。这个输出应该为你提供你正在寻找的信息。它将使用QEI中断来计算完成的回合数。根据QEI的方向，中断将递增或递减该索引值。

    Hi Bizard,
 
In the QEI block GUI you should have the "Index counter (Number of completed rotation)" output available.
This output should provide you the information you are looking for.
It will use the QEI interrupt to count the number of completed turn. Depending on the direction QEI, the interrupt will increment or decrement this Index value.

嗨，鲁宾，非常感谢你的帮助，我没有意识到这已经是最好的了。

    Hi Lubin,
Thank you very much for your help, I didn't realize that it was already there
 
all the best
