PIC24EP256GU810 ECAN pins?
PostPosted: Wed Jul 22, 2020 1:53 am     Reply with quote

Hello everyone.

I am starting with PIC24EP256GU810 for j1939 CAN-BUS. My first issue:
I can't see the TX & RX ECAN pins around this PIC.
Are there physical pins to ECAN module? or they are remappable only?
The datasheet don't sow this info.

Thanks in advance.

The datasheet does show this.
Table 1-1.
C1RX, C1TX, C2RX, & C2TX have the entry 'yes' for PPS.

Any pin that is PPS, always has to be setup to a physical pin with
#PIN_SELECT
It is totally up to you which physical pins these are connected to.

Every pin on this PIC, except the USB signals supports PPS. However
remember that the TX lines can only go to 'RP' pins, not 'RPI' pins.
So there are only about 15pins available for the output connections.

Thanks Ttelmah,

I can see RB0, RC1... on the pinout of PIC24EP512... but not C1RX, C1TX...

So it was my doubt.

Finally, it's the same: Only remappable pins.

Thanks a lot
Regards
