I have spent 4 days and I can't get this working. I read a lot and still not get any closer. I need to have additional UART ports for Arduino MKR 1500. Not one, not two, I need to have MAX available UART ports. How many total devices I can connect using UART.

enter image description here

I see this table in my dreams at night, and I can't figure out how to use it. The only one I got succesfully working is example from Arduino web site:

Uart mySerial (&sercom3, 0, 1, SERCOM_RX_PAD_1, UART_TX_PAD_0);

Please help. I would appriciate if you just create a simple .ino file (WORKING!!!) with let's say 4 UARTs. Please!!!

Also will the code work for this:

void SERCOM0_Handler()
{
  mySerial2.IrqHandler();
  mySerial3.IrqHandler();
}

Or I can only have one UART per SERCOM?

do you have `pinPeripheral(0, PIO_SERCOM);`? – Juraj Aug 08 '19 at 06:48
and confusing is that 0 is TX and 1 is RX. the tutorial describes it wrong. the pads settings count, not the order in constructor or the comments at pinPeripheral cals – Juraj Aug 08 '19 at 06:48
