嫌錢至少有10 篇以上在討論 CAN 速率的計算，可以到討論區下去 Search 一下，應該不難找到的。

請問以下我哪個地方算錯了呢?
(18F8680, APP023,APP023-1) 用示波器量一個 bit 的時間反推回去,都達不到我要的速率! CANInitialize ( 2, 0, 1, 1, 0, ...... SJW :2 => 3TQ BRP :0 PHSEG1 :1 => 2TQ PHSEG2 :1 => 2TQ PROPSEG :0 => 1TQ ==> 總共 8 TQ BRP=0 => TQ = 0.2us Tbit = 1.6us <== 我量出來的位元時間是幾百us 請問哪裡算錯了嗎?
