Seeeduino Xiao

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 <PZEM004Tv30.h> #include <SoftwareSerial.h> SoftwareSerial pzemSWSerial(6, 7); PZEM004Tv30 pzem; void setup() { SerialUSB.begin(115200); pzem = PZEM004Tv30(pzemSWSerial); while (!SerialUSB) { delay(100); } SerialUSB.println("start"); } void loop() { }

Hi.
Try the basic example :

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

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

Don't work. I'm error here: Il giorno dom 25 lug 2021 alle ore 13:40 sergiocntr < ***@***.***> ha scritto:

Hi. Try the basic example : `SoftwareSerial pzemSWSerial(PZEM_RX_PIN, PZEM_TX_PIN); * PZEM004Tv30 pzem(pzemSWSerial);* void setup() { /* Debugging serial */ Serial.begin(115200); }` — You are receiving this because you authored the thread.

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.

I'm try all.... don't work. tanck's for your time. Il giorno dom 25 lug 2021 alle ore 16:28 sergiocntr < ***@***.***> ha scritto:

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:

PZEM-004T-v30/src/PZEM004Tv30.h

Lines 49 to 52 in b27887e

	#if (not defined(PZEM004_NO_SWSERIAL) && (defined(__AVR__) || defined(ESP8266)) && not defined(ESP32))
	/* Software serial is only available for AVRs and ESP8266 */
	#define PZEM004_SOFTSERIAL
	#endif

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() {
}

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 Diego Il giorno dom 25 lug 2021 alle ore 20:30 Jakub Mandula < ***@***.***> ha scritto:

I've tried every options suggested here and no luck :(
