there is a small mistake in the last commands: ampy put boot.py that is ampy put {{local_file_path}} # implicit remote path and name with json and the JSON-File

@farmeuhly said in PIN number and shields: Hello, happy new year ! I'm back on my tests... I have a lot of problems. 1 : problem for uploading sketch on the board, i should remove the "bottom" of the m5stack and bush the boot button for it to work ! And sometimes it fails anyway... 2 : I tried to stop the pins on the "bottom" with the sketch "blink" and those that work are : 0, 2, 3, 5, 12, 13, 15, 16, 17, 19, 21, 22, 26 The others (1, 18, 23, 25, 34, 35, 36) doesn't work. 3 : I don't understand why the same simple sketch work fine on arduino uno board and don't work on the m5stack. I put the #include <M5Stack.h>, m5.begin(), m5.update... But i have the impression that the selected pins don't work. What i'm doing wrong ? Because the esp32 and the mega328p do not have the same pins. The AtMegas have defined pins but the esp32 uses a matrix of functions that can be assigned to each i/o pin. Check out the esp32 data sheet for these functions.

I solved this problem: from m5stack import * import wifisetup wifisetup.auto_connect()

Glad it worked, Merry christmas bud :p

@cepics said in arduino espnow.h: @yalezy tnks but trying to add zip library, arduino IDE 1.8.7 say: Specified folder/zip file does not contain a valid library Confirmed, I'm getting the same error. .h and .c files need to be a folder named src

@jikuch Hi, can you tell me: if I change something in ip5108 through i2c (for example disable auto-standby), will this changers be saved, or i must make this changes (with software) each time when i start device?

Excellent. Thank you!

It's all a matter of taste I guess. Three buttons just aren't that many, I prefer to use as few keypresses as possible. Nobody is going to write their thesis on it: it's for WLAN passwords and the like.

Thanks for your help, I'll try to follow your directions in the following days.

Very cool Sergey. Thanks for sharing

@lastcaress 在 M5Fire and MLX90640 works 中说： The code was compiling, it just didn't do anything when I connected the camera. Tried m5 core, fire and nothing. Tried today with m5go and it worked! [image: a7NXJWg.jpg] I think i have too many m5stack things thats quite a collection you have there.

Hey Lukas, This won't work. The mpu9250 module expects to find an MPU6500 accelerometer so even instantiating an mpu9250 object will fail during init(). Even if I remove the part of the code that checks for the MPU6500, instantiation will still fail when it attempts to initialize the magnetometer by writing to one of it's registers.

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
