抱歉抱歉!!
自己剛剛解決的 原來BRP可以設為 0 AN738 page4 裡面寫的好像不太正確 BRP [in] BRP value as defined in PIC18CXX8 data sheet (must be between 1 through 64).

請問各位高手:
我照著CAN202 pdf給的公式計算CAN的bit timing, 算出來的數值不對 又不知道錯在哪, 我Fosc=16MHz,Baud Rate=1Mbps Tbit=1uS N=8 BRP=[(16M/8)/(2*1M)]-1=0 ?? 如果假設 BRP=1,算出來的結果如下 SJW=3 BRP=1 PHSEG1=2 PHSEG2=3 PROPSEG=2 這個結果我試了無法傳送,請問我錯在哪邊?? 謝謝!!
