Seeeduino Xiao

[diegomariani]

How can use your library in Seeeduino Xiao (SAMD proccessor)?

[mandulaj]

Hey, Sorry I don't have a Seeeduino so can't test it for you. However besides potential problems with SoftwareSerial, I see no reason why it should not work.

I have problems with the Seeeduino.

If you want you can connect with desktopremoto, and we can create a suitable class for SeeeduinoXiao as well.

With the SoftwareSerial I get the following error with the following program:

include

include

SoftwareSerial pzemSWSerial(6, 7);

PZEM004Tv30 pzem;

void setup() {

SerialUSB.begin(115200);

pzem = PZEM004Tv30(pzemSWSerial);

while (!SerialUSB) { delay(100); }

SerialUSB.println("start");

}

void loop() { }

This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences.

Hi. Try the basic example :

`SoftwareSerial pzemSWSerial(PZEM_RX_PIN, PZEM_TX_PIN); PZEM004Tv30 pzem(pzemSWSerial);

void setup() { / Debugging serial / Serial.begin(115200); }`

[diegomariani]

Don't work. I'm error here:

a) this line inside setup() is not needed and broke your sketch: pzem = PZEM004Tv30(pzemSWSerial);

b) your declaration miss the argument: PZEM004Tv30 pzem;

This is the good one: PZEM004Tv30 pzem(pzemSWSerial);

Fix this two issues in your sketch.

[diegomariani]

I'm try all....

don't work.

tanck's for your time.

I think what might be the problem is the way we conditionally enable SoftwareSerial in the library only on some platforms (AVR and ESP8266).

See here: https://github.com/mandulaj/PZEM-004T-v30/blob/b27887e2118f67bda1bb100e6c82a859dafda1c9/src/PZEM004Tv30.h#L49-L52

So perhaps try force enabling the Software serial by defining PZEM004_SOFTSERIAL manually.

#define PZEM004_SOFTSERIAL

#include <PZEM004Tv30.h>
#include <SoftwareSerial.h>

SoftwareSerial pzemSWSerial(6, 7);
PZEM004Tv30 pzem(pzemSWSerial);

void setup() {

    SerialUSB.begin(115200);

    while (!SerialUSB) { 
         delay(100); 
    }

    SerialUSB.println("start");

}

void loop() {
}

[diegomariani]

I'm try this too....

But I muss buy a new board, while seeeduino work with 3.3V, e I muss have 5V.

Tank's for all
