I have a problem in finding ECAN pin's that is C1TX, C1RX, C2TX and C2RX in dsPIC33EP256MU810 (or) dsPIC24EP256GU810 pin diagram. The following link is the data sheet for the above mentioned PIC (https://elcodis.com/parts/3706234/DSPIC33EP512MU810-IPF.html). Pls help me out. Thanks in advance.

Hi,

Think thats is because its down to you what pins the Can modules uses.

See the datasheet PPS section register RPINR26 on page 224.

Thank You wp100. That was helpful:smile:

As wp100 indicated many of the peripheral module I/O must be mapped to a specific physical pin of the device.

This approach allows the device to offer many different peripheral modules, while conserving the number of require port pins to only those peripheral modules utilized.

The required techniques of mapping are covered in the following reference:

Section 30. I/O Ports with Peripheral Pin Select (PPS)

The dsPIC33 series also shares many of the features offered by the PIC24H series:
