Bonjour à tous,

Je passe de l'arduino au stm32f103c8. Je pense avoir tout installé correctement sur mon IDE Arduino afin de pouvoir programmer le STM32. J'arrive à injecter le programme blink et ca fonctionne.
J'ai donc décidé de passer à un programme plus lourd et j'ai donc installé toutes les bibliothèques nécessaires. La compilation de déroule sans problème mais quand je tente le téléchargement j'ai toujours l'erreur :" Wrote address 0x08004b00 (87.54%) Got byte 0x22 instead of ACK
Failed to write memory at address 0x08004c00" ce n'est pas non plus un gros programme puisqu'il ne prend que 21932 octets (33%) de l'espace de stockage.

Une erreur est survenue lors du transfert du croquis

Un grand merci à ceux qui pourront jeter un coup d'oeil et m'aider.

C'est possible que le problème vienne du fait que j'utilise un adaptateur USB/Serie en 5Volt ?

[Vincent PETIT]

Salut,
C'est compliqué de répondre si tu ne nous donnes pas la référence de la carte de développement que tu utilises (celle où est implanté ton microcontrôleur STM32F103C8).

- Si tu utilises un convertisseur USB/Série 5V alors que la carte de développement, dont on ignore tout pour l'instant, est en 3.3V, elle ne va pas apprécier.
- Est ce que ce matériel a déjà fonctionné avant ?
- Est il neuf et si oui, chez quel fournisseur a t-il était acheté ? Si ça vient d'Aliexpress alors c'est forcément un produit qui n'a pas passé les tests qualités (c'est pour ça que tout est si peu cher sur ce site) et un défaut de qualité ça va d'une police d'écriture de travers (pas grave) a des défauts de tolérances ou spécifications (entre le "en panne" et "fonctionne a peu prés bien").

ps : Je ne dis pas qu'il ne faut pas acheter sur ce site, je dis qu'il faut prendre ça en compte. Pour un premier développement ou pour un prototype, jamais je ne prendrai de composant chez eux car c'est un coup a tourner en rond sur un problème pendant 10 ans alors que c'est le truc qu'on a acheté qui ne marche pas Mieux vaut démarrer avec quelque chose de fiable, mettre au point et une fois que c'est fait, là on achète chez Aliexpress.

[Starjuice]

Salut,
Désolé du manque de renseignements.

Mes 2 cartes sont des blue-pill acheté chez aliexpress ,
Elles fonctionnent quand je rentre des petits programmes pas long.

Je suis sous linux, j'ai même essayé de chargé le bootloader mais j'ai aussi une erreur.

J'ai fait aussi le test avec un CD4050BE pour avoir une tension TX et RX de 3,3V. Mais c'est pareil sur mes 2 cartes...
Je vois plus trop de quoi ca peut venir, je désespère car si c'est j'ai pris des STM32 c'est pour utiliser un écran TFT ili9341...

[Vincent PETIT]

Salut,

Elles fonctionnent quand je rentre des petits programmes pas long.

Tu dis avoir un convertisseur USB/Série 5V, qu'elle est la tension de fonctionnement de la carte micro ? 3.3V ou 5V ?

Si la carte micro est alimentée en 3.3V alors il faut un convertisseur USB/Série 3.3V aussi sinon la carte micro va casser, ce n'est qu'une question de temps. Quand bien même on parlerait de I/O 5V tolérant côté micro, c'est forcément en mettant à contribution les diodes de protections internes du composant, ce qui n'est jamais bon.

Je suis sous linux, j'ai même essayé de chargé le bootloader mais j'ai aussi une erreur.

Peux tu nous montrer la même sortie de console mais pour un petit programme, c'est à dire lorsque tu arrives à programmer.

[Starjuice]

Merci de prendre le temps de me répondre.

Normalement elle fonctionne en 3,3V. Mon convertisseur est en 5V mais je passe par un optocoupleur pour avoir du 3,3v mais même sans j'ai exactement le même souci.

Je te renvoie le message.
