您好，我在QCY32 EP256MC506的MCLV2卡上使用QEI。我用Matlab编程我的微控制器，我没有找到最大的QEI率。我使用4096行的编码器。在低速，大约1000 rPM，我的控制是完美的。我比较了测量结果与另一个装置并行，它是完美的。当我增加速度时，由于计数问题而失去同步。我尝试转向大约600rPM，这导致1.638兆赫。这张卡片可以吗？还是太多了？最好的问候，Romain DELPOUX 以上来自于百度翻译 以下为原文 Hello, I'm using the QEI on a MCLV2 carte with dspic33ep256mc506. I use matlab to program my microcontrolleur. I do not manage to find the maximum rate for the QEI. I use an encoder with 4096 lines. At low speed arround 1000rpm, my control is perfect. I compared the measured psotion with another device in parallel and it's perfect. As soon as I increase the velocity the synchronism is lost due to count problem. I try to turn arround 6000rpm, which leads to 1.6384 MHz. Is it possible with this card or it's too much? Best regards. Romain DELPOUX

我试着总结一下如何测量一列0到300赫兹的方波脉冲的频率。脉冲源是一个速度传感器。最低的移动输入将是2Hz。我认为正确的方法是配置一个计时器来增加一个输入脉冲，第二个计时器设置一个固定的间隔。Microchip页面说16F1508有：4捕获/比较/ PWM外围设备，但我没有看到任何关于1508个文件的捕获模式，如16F627 / 8… 以上来自于百度翻译 以下为原文 I'm trying to wrap my head around how to measure the frequency of a train of square wave pulses that can range from 0 to 300hz.the pulse source is a speed sensor.. it's lowest moving input would be 2hz.. 0hz when stopped. am I right in thinking the best way is to configure a timer to increment on an incoming pulse, and a second timer to set up a fixed interval?the microchip page says the 16f1508 has:4 Capture/Compare/PWM Peripheralsbut I don't see anything in the 1508 docs about a capture mode like the 16f627/8 does...
