Hi All.
I was read LPC111x/[B]LPC11Cxx[/B] User manual UM10398 and i can't find [B]CAN speed(100,250,500,1M) \ CAN bit timing register[/B] table, how can get it for us?

And i find error in Table 209, see row "Description", please check it.

Thanks.

Hello LexaryStyle,

Quote:
0010: CAN_CLK = PCLK divided by 3
0010: CAN_CLK = PCLK divided by 4.

is type-error ... will be changed. Should be

Quote:
0010: CAN_CLK = PCLK divided by 3
0011: CAN_CLK = PCLK divided by 4.

Thanks.

Would suggest to use 48MHz:

100k: 0x127
200k: 0x113
250k: 0x10F
500k: 0x107
1000k: 0x103

Yes, what write in [COLOR=Red]CANBT[COLOR=black] if use 12Mhz oscillator for:
100Kbps
200kbps
250kbps
500kbps
and 1000kbps
