I'm still missing a CAN sample in LPCOpen 2.08 LPC15xx?

Just something to work with?

Any news about CAN Library for LPC15xx this week :quest:

Hi,

The LPC15xx has ROM-based CAN support. An LPCOpen CAN example demonstrating the use of the ROM CAN support is scheduled for end of this month. Sorry for the delay.

Thanks for clarification...

I'm short of time so I asked a colleague today if he could write a quick and dirty sample to test my new Dev-Boards (LPC1549 LQFP64).

A few hours later he emailed me this LPCOpen main.c, which is working fine here.

Perhaps you have to change CAN pin muxing and LEDs for your board...

It's working fine here, too

Just added LQFP48 CAN SWM setting and changed UART settings in board.c and board_sysinit.c.
PIO0_13/18 are switched there as UART since 'lpc_board_nxp_lpcxpresso_1549' is LQFP64.

#ifdef LQFP64
//CAN signal muxing LQFP64
 Chip_SWM_MovablePortPinAssign(SWM_CAN_TD1_O , 0, 31);
 Chip_SWM_MovablePortPinAssign(SWM_CAN_RD1_I,  0, 11);
#endif
#ifdef LQFP48
//CAN signal muxing LQFP48
 Chip_SWM_MovablePortPinAssign(SWM_CAN_TD1_O , 0, 18);
 Chip_SWM_MovablePortPinAssign(SWM_CAN_RD1_I,  0, 13);
#endif

Thanks a lot...

...meanwhile it's April here. Any progress?

Mr. R2D2 was nice enough to point me at this thread.

It seems a little disappointing that a major peripheral like this would not have more support. Hopefully this can be resolved soon.

Just in case there is information posted on the thread I started I am putting the link here.

Thanks everybody for sharing as this is the most information I have found to date regarding CAN use on the LPC1549.
