Hi, i've seen that some people successfully created additional hw serial i/f for mkr1310 using D0/D1 pins by configuring sercom ... however, my problem is that i must implement an additional hw serial i/f using pins D4(RX) and D5(TX), since i am plannig to use a shield in which one serial i/f is attached to those pins (another one is available for pins D13/D14 to Serial1), as can be seen:
However, i'm not sure it is possible for mkr1310, since as far as i have seen in variants.cpp,D4 and D5 pins use sercom4 (in particular sercom4/pad02 and sercom4/pad03), which is also used for Serial2 (LoRa module).
Could anynone confirm that it is possible?. In that case, i would really appareciate if any can provide a reference of the initialization code for this additional serial i/f. Thanks
