請問(wèn)各位我在做好高速計數器時(shí)，用接近或霍爾開(kāi)關(guān)代替編碼器，怎么觸發(fā)一下他產(chǎn)生好幾個(gè)脈沖

按理是不是應該觸發(fā)一下他產(chǎn)生一個(gè)脈沖啊

用接近或霍爾開(kāi)關(guān)代替編碼器，那你也可以用普通計數代替高數計數啊，這個(gè)用法看場(chǎng)合的啊，不同的計數器用在不同的場(chǎng)合。如果說(shuō)你這個(gè)接近或霍爾開(kāi)關(guān)代替編碼器的話(huà)，那么也沒(méi)有必要用高數計數，這里高數計數的優(yōu)點(diǎn)沒(méi)有得到發(fā)乎，另一個(gè)方面缺點(diǎn)被你用到了，使用不當
