@playthegame 在 PIN number and shields 中说：

Thank you, I will continue my tests. The matches will help me!

Thank you for the info @ajb2k3 and @PlayTheGame !
I will order the connectors.
I did the quick test and it works well, but I used the proto module to get the pins numbers.

Is there a table with the corresponding pin numbers of the proto module and the back of the m5stack core?

For example, where is pin 13 on the back of the m5stack core?

I have everything to learn!

Yes, i've seen. I've bought one of this but the connector on the nema 17 is not the good one to plug on the stepmotor module.

Thank you PlayTheGame, it's not clear for me...
can you help me on a concrete example?
I have a step motor driver TB6600, I use the following arduino sketch by connecting the PIN 2, 5 and 8 on the Arduino Nano.

// defines pins numbers
const int stepPin = 5;
const int dirPin = 2;
const int enPin = 8;

void setup() {
// Sets the two pins as Outputs
pinMode(stepPin,OUTPUT);
pinMode(dirPin,OUTPUT);
pinMode(enPin,OUTPUT);
digitalWrite(enPin,LOW);

}

void loop() {

digitalWrite(dirPin,HIGH); // Enables the motor to move in a particular direction
// Makes 200 pulses for making one full cycle rotation

for(int x = 0; x < 200; x++) {
digitalWrite(stepPin,HIGH);
delayMicroseconds(200);
digitalWrite(stepPin,LOW);
delayMicroseconds(200);
}

delay(1000); // One second delay

digitalWrite(dirPin,LOW); //Changes the rotations direction
// Makes 400 pulses for making two full cycle rotation

for(int x = 0; x < 400; x++) {
digitalWrite(stepPin,HIGH);
delayMicroseconds(500);
digitalWrite(stepPin,LOW);
delayMicroseconds(500);
}

delay(1000);

}

I would like to use the same thing on the m5stack but I can not find the good PIN.

thank you

Hello, I am looking for a table of correspondence of the pins numbers used in the arduino sketches and the pins of the M5stack core.
I test with the sketch "blink" and apart from the pins G2 and G5, I can not find.
Can you help me ?
I have to connect different shields, step motor, relay, but i can't find the good pins.
Thank you

I'm interested too ! I follow.

Hello again,
i've made a sketch on arduino ide to control a nema 17 stepper motor with the shield L298N

here is the sketch :
/*
Controle de moteur pas à pas avec un L298N
Le moteur est connecté sur les broches 2,3,4 et 5 de l'Arduino
Le fil de masse (GND) est commun aux 2 platines.
*/

#include <Stepper.h>

const int NbPasParTour = 200; // Nombre de pas pour 360 degres
Stepper Moteur1(NbPasParTour, 2, 3, 4, 5); // Initialise le moteur sur les broches 2 à 5

void setup()
{
Moteur1.setSpeed(60); //Vitesse de rotation du moteur
Serial.begin(9600); //Initialise le moniteur série
}

void loop()
{
Serial.println("Sens horaire"); //On fait 1 tour en sens horaire
Moteur1.step(NbPasParTour);
delay(1000); //Pause 1 seconde

Serial.println("Sens anti-horaire"); //On fait 1 tour en sens anti-horaire
Moteur1.step(-NbPasParTour);
delay(1000); //Pause 1 seconde
}

It's work fine !

But when i try on the m5, on the PIN 3, 1, 16, 17 with this sketch, the motor only vibrate :
/*
Controle de moteur pas à pas avec un L298N
Le moteur est connecté sur les broches 3, 1, 16, 17 du m5
Le fil de masse (GND) est commun aux 2 platines.
*/
#include <M5Stack.h>
#include <Stepper.h>

const int NbPasParTour = 200; // Nombre de pas pour 360 degres

Stepper Moteur1(NbPasParTour, 3, 1, 16, 17); // Initialise le moteur sur les broches

void setup()
{
Moteur1.setSpeed(100); //Vitesse de rotation du moteur
m5.begin();
M5.Lcd.setBrightness(200);

M5.Lcd.setTextColor(0xffff);
M5.Lcd.setTextSize(3);
M5.Lcd.setCursor(50, 20);
M5.Lcd.print("M5 Seeder");
}

void loop()
{
M5.Lcd.setTextColor(0x7bef);
M5.Lcd.setTextSize(2);
M5.Lcd.setCursor(55, 60);
M5.Lcd.print("Sens horaire");
Moteur1.step(NbPasParTour*2);
delay(1000); //Pause 1 seconde

M5.Lcd.setTextColor(0x7bef);
M5.Lcd.setTextSize(2);
M5.Lcd.setCursor(55, 60);
M5.Lcd.print("Sens anti-horaire");
Moteur1.step(-NbPasParTour);
delay(1000); //Pause 1 seconde

m5.update();
}

Any idea ?
thank you

I have a question, maybe stupid but i'm a noob :)
I have burned m5go, all is ok. I can connect with uiflow.
But can i use arduino IDE to make my sketches and upload them on the m5 and have an access with a menu as like in uiflow ?
I need more practice with blocks before i can use uiflow.

Thank you

Hello, thank you Julian, i've tried this sample. It work fine.
But is there a sample of this code with comments too really understand each part ?
Is there some exemples with "fritzing" draw ?

thank you.

Hi,
i've just discovered M5stack, great product !

I am a farmer and I produce organic vegetables.
I have a project of pneumatic seed drill with venturi effect.
I know a little arduino but not at all micropython.
I am a little lost, I would like to know where to start my project.
I have to control stepper motors and a solenoid valve.

I would like to start simply by programming a stepper motor to advance a conveyor belt.

Any ideas to help me?
thank you very much
