  • QEI - INX CNT can not count, when A / B(SIGMODE =0) stop. 

    中文 : 功能說明 : 設計Z偵測到脈波輸入時,觸發中斷,清除AB向脈波計數值。   問題描述 : QEI - 當AB相沒有收到任何輸入脈波時,INCNT無法計數。 當AB相有偵測到輸入脈波時,INCNT才會計數。 這現象會導致,編碼器AB 輸入停止時,無法成功清除AB相計數值。 有其他方法可以讓Z 計數獨立計算,不受INGATE(index gating configuration) 影響嗎?   Engl...

  • Driver for LCD ST7735, LPC1768/9

    Hi,   I have a LCD driver for a LPC1768 or (LPC1769) device. It works somehow. But, it is far from being efficient, it is slow. Even though I played with SPI speed from 1Mhz up to 25Mhz, it didn't make any diffe...

  • SCT -  PWM 200K Hz 100puse,not use interupt to STOP。

    SCT0產生一個200KHz AB pulse輸出波形,當user設定100次pulse(200KHz AB) 後,自動將SCT0關掉. (不用中斷去關掉SCT0,因為隨MCU的負載量變大,會導致來不及去關掉SCT0,導致額外多輸出101次的波形) SCT0有甚麼方法可去完成這個應用?不使用中斷。 -----------------------------------------------------------------...
