Software Serial for Arduion MKRwifi 1010

Using Arduino Programming Questions
1

Hi everyone, I'm working on Arduino MKRwifi 1010 with Arduino library for PM sensors with serial interface. I found a PM serial library on GitHub but it's for arduino UNO :
PMserial/src at master · avaldebe/PMserial · GitHub.
I tried a lot to make this library working on Arduino mkr but no success. Can anyone help me how I can modify it?

My Sketch arduino:

#include <PMserial.h>

Uart Serial1(&sercom5, 13, 14, SERCOM_RX_PAD_3, UART_TX_PAD_2);

void SERCOM5_Handler()
{
  Serial1.IrqHandler();
}
SerialPM pms(PM, 13, 14);  // PM Serial, RX, TX

void setup() {
  Serial.begin(9600);
  Serial1.begin(9600);
  pms.init();                   // config serial port
}

void loop() {
  pms.read();                   // read the PM sensor
  Serial.print(F("PM1.0 "));Serial.print(pms.pm01);Serial.print(F(", "));
  Serial.print(F("PM2.5 "));Serial.print(pms.pm25);Serial.print(F(", "));
  Serial.print(F("PM10 ")) ;Serial.print(pms.pm10);Serial.println(F(" [ug/m3]"));
  delay(10000);                 // wait for 10 seconds
}

Thanks in advance

Can anyone help me how I can modify it?

Replace HardwareSerial by Uart in the .h and .cpp files and use the constructor that provides the serial interface object as a parameter and not the pins.

Thanks pylon , I tried a lot but no success if you can explain more I will appreciate that.

I replaced HardwareSerial.h by uart.h in the library(in .h and .cpp) (I found uart library on Github Arduino/cores/esp8266 at master · esp8266/Arduino · GitHub ) but I always get the same error:

Did I write "uart"? C/C++ is case sensitive!

If you changed your code and get problems, post it again.

@pylon, the library is good without changes. only the hw Serial constructor must be called with the Serial1 from core, because Serial is USB
