Ecran OLED ATtiny

pepin38 · October 24, 2022, 12:18pm

Bonjour à tous !

J'essaie depuis 2 jours de programmer un écran OLED 0.96" chinois sur mon ATtiny 85.
J'ai réussi à faire fonctionner la lib "SSD1306_minimal.h", mais je n'arrive pas à lui faire imprimer une variable...

Après pas mal de recherches j'ai vu que d'autres lib devraient êtres plus agréables à utiliser (modification de la taille du texte notamment et surtout impression de variables), mais je 'arrive pas à les faire fonctionner...
J'ai testé "SSD1306AsciiWire.h" et "Tiny4kOLED.h" mais même en ouvrant simplement un fichier d'exemple, j'ai des erreurs dès la vérification.
J'imagine que j'ai dû louper une étape, il me manque peut être des fichiers ou je ne sais quoi...

Pour plus d'infos sur le projet, j'essaie de faire une lampe stroboscopique pour mesurer la vitesse de rotation de moteurs. La partie flash pilotée par un potar fonctionne bien mais pas moyen d'imprimer ma variable "RPM" sur l'écran Oled...

voici les messages d'erreurs.

Merci d'avance

Arduino : 1.8.13 (Windows 10), Carte : "ATtiny, ATtiny85, 1 MHz (internal)"

On retrouve ces mêmes messages d'erreur dans cette discussion :

@johnwasser répond ceci:

It looks to me like the SPI library that was selected does not support the ATtiny85 processor. Are you sure your sketch will run on an ATtiny85?

Moi je ne connais pas l'Attiny85, mais c'est une piste à explorer. Il existe la bibliothèque TinySPI mais je ne sais pas si elle est compatible avec celle de ton écran.

Ton écran a un driver SSD1306. Il faudrait chercher une bibliothèque pour cet écran.
J'ai trouvé celle-ci mais elle concerne le SD1331. Il fait 96x64, ce n'est peut-être pas la même résolution.

Es-tu sûr que ton écran est en SPI ? As-tu un lien vers le site vendeur ou une datasheet ? Voire une photo ?
Pour un SSD1306 en I2C, j'ai trouvé cette bibliothèque :

D'ailleurs Tiny4kOLED est aussi pour un écran I2C.
Si ton écran est bien en SPI, la réponse est ici :

Voir la réponse de @olikraus : bibliothèque u8g2 avec le constructeur U8X8_SSD1306_128X64_NONAME_SW_I2C

Il y a aussi cette bibliothèque, mentionnée dans le même post :

pepin38 · October 24, 2022, 2:34pm

Merci pour ta réponse.
Mon écran est en I2C, d'après ce que j'avais vu la bibliothèque SSD1306_minimal.h était pour I2c et le seul vrai problème qu'elle me pose est qu'elle ne permet pas (ou alors je n'ai pas trouvé) d'afficher une variable. Pour les 2 autres que j'ai citées, je ne sais pas j'avoue que je m'y perds, surtout dans les pages en anglais (pas pratique pour coder...).

Je vais regarder la bibliothèque I2C que tu as trouvée, potasser un peu ce que tu as envoyé et je vous tiendrai au courant.

Merci

ZX80 · October 24, 2022, 2:48pm

Essaie ceci avec SSD1306_minimal

// Circuits DIY
// For Complete Details Visit -> https://circuits-diy.com  

#include "SSD1306_minimal.h"
#include <avr/pgmspace.h>

#define DEG "\xa7" "C"

SSD1306_Mini oled; // Declare the OLED object

void splash() {
 oled.startScreen();
 oled.clear(); // Clears the display

 oled.cursorTo(0, 0); // x:0, y:0
 oled.printString("   Hello World!");
 oled.cursorTo(0, 10); // x:0, y:23
 oled.printString("     ATtiny85!");
 oled.cursorTo(0, 20); // x:0, y:23
 oled.printString("   Circuits DIY");
 oled.cursorTo(0, 30); // x:0, y:23
 oled.printString("    JLCPCB.com"); 
}

void setup() {
 oled.init(0x3C); // Initializes the display to the specified address
 oled.clear(); // Clears the display
 delay(1000); // Delay for 1 second
 splash(); // Write something to the display (refer to the splash() method
}

lesept · October 24, 2022, 2:50pm

As-tu essayé print ou println tout simplement ?

int n=20;
oled.cursorTo(0, 0);
oled.println(n);
float x = -2.3;
oled.println(x,2);

Si tu jettes un oeil ici, il n'y a que deux méthodes : printChar() et prinString() :

      What is it?
        This library is derived from GOFi2cOLED library, only for SSD1306 in I2C Mode.
        As the original library only supports Frame Buffered mode which requires to have
        at least 1024bytes of free RAM for a 128x64px display it is too big for smaller devices.

Mais j'estime tout de même que convertir un integer en chaîne ne nécessite pas un effort colossal.

ZX80 · October 24, 2022, 3:00pm

oups j' avais vu "variable", J' avais pas pensé a nécessairement un nombre...

pepin38 · October 24, 2022, 3:38pm

@ZX80 J'ai testé ce code il fonctionne bien mais impossible d'afficher des nombres provenant d'une variable int

@lesept les fonctions print et println ne fonctionne pas j'avais essayé aussi...

@hbachetti j'avais en effet consulté cette doc et j'ai testé les 2 méthodes d'impression. Débutant je ne comprends pas tous c'est la première fois que j'utilise un écran I2C et la première fois également que je suis sur ATtiny...

La j'avoue que j'ai pas du tout compris ce que ça veut dire...
[Edit] si en fait tu veux dire convertir ma int en char c'est ça ?)

Si j'essaie d'imprimer une variable int j'ai des caractères spéciaux à l'écran. Ce qui du coup semblerait normal ? Du coup aucun moyen d'afficher ma variable numérique avec cette bibliothèque ?

lesept · October 24, 2022, 3:40pm

Tu peux utiliser sprintf si cette instruction est supportée par l'Attiny.

https://cplusplus.com/reference/cstdio/sprintf/

ZX80 · October 24, 2022, 4:04pm

Peut-etre comme cela
https://forum.arduino.cc/t/itoa-function/975977

pepin38 · October 24, 2022, 7:49pm

J'ai regardé tout ça et j'avoue que je n'y comprends rien
Comment fonctionne sprintf ? C'est du chinois pour moi... Vous auriez un site qui apprend tout depuis la base ? Toutes ces pages sont très difficiles à comprendre pour un débutant...

[EDIT] C'est bon j'ai parcouru pleiiiin de sites qui parlaient de la fonction sprintf et j'ai finalement compris (je pense) plus ou moins comment elle fonctionne. En tout cas ça marche j'ai bien ma valeur à l'écran merci
