CAN MQX

I'm developing a CAN interface for MCF52259.

My project is based on MCF52259

demoboard.

I use MQX 4.0 and I'm using that example will

attached.

(C:\Freescale\Freescale_MQX_4_0\mqx\examples\can\flexcan)

need to know which ports sets the MQX driver uses

(PUC0,PUC1) or

(PTH5,PTH4).

You would have a can interface circuit to suggest?

Hello Gustavo,

According with the gpio_init.c file located at the path C:\Freescale\Freescale_MQX_4_0\mqx\source\bsp\m52259demo

The pins used are PUC0,PUC1

/*FUNCTION*-------------------------------------------------------------------

* Function Name : _bsp_flexcan_io_init

* Returned Value : 0 for success, -1 for failure

* Comments :

* This function performs BSP-specific initialization related to FLEXCAN

*END*----------------------------------------------------------------------*/

_mqx_int _bsp_flexcan_io_init

(

uint_8 dev_num

)

{

VMCF5225_STRUCT_PTR reg_ptr = _PSP_GET_IPSBAR();

switch (dev_num) {

case 0:

reg_ptr->GPIO.PUCPAR = (reg_ptr->GPIO.PUCPAR & ~0x03) | 0x02;

reg_ptr->GPIO.PUCPAR = (reg_ptr->GPIO.PUCPAR & ~0x0C) | 0x08;

break;

default:

return -1;

}

return 0;

}

Have a great day,
Sol
