Bonjour à tous,
Voila, je souhaite m'initier aux µC 32 bits. Pour cela mon choix s'est tourné sur les ARM CORTEX. J'ai donc acheter une carte NUCLE-F429ZI . Nucleo-144.
Dans un tout premier temps j'ai essayé le logiciel Mbed permettant de faire un programme en ligne. Ensuite on clic sur compile on télécharge le .bin et on le met dans le dossier de la carte nucléo ( détecter comme une clé USB). Je vois bien un transfert donnée sur ma carte avec un clignotement rouge/vert de la led. Et hop ma led prévue se met à clignoter. Jusque la c'est nickel.
Le HIC c'est que je ne souhaite pas utiliser une version en ligne, trop contraignante. je me suis donc tourné vers SW4AC6 pour l'IDE couplé avec STM32CubeMX pour la configuration. Et ici les problèmes commencent !
Je n'arrive absolument pas à charger un clignotement de led.
Dans cube, je rentre ma carte et je lui demande de me générer le code. je reste tout par défaut. Je rentre un nom de projet , j'indique que l'IDE est pour SW4STM32 et je génère le code.
Le code s'ouvre directement dans AC4STM32 nickel !.
Je fais un petit build histoire de vérifier qu'il n'y a pas d'erreur. nickel.
Je me retrouve donc avec un programme vierge sans erreur apparemment.
Je vais dans le dossier "Core" puis "Src" et j'ouvre le main.c qui ressemble a ça :

Je pense que jusque là j'ai configuré mes I/O, mon horloge et deux-trois bricoles.
Je me permets donc de rajouter dans le main.C et dans la boucle "while" ces deux lignes :
Ceci dans le but de faire clignoter la led 1 qui est brancher sur la pin PB0 il me semble.Code:HAL_GPIO_TogglePin(GPIOB,GPIO_PIN_0); HAL_Delay(400); //delay 100ms
Je "build all" , il se passe queqlues bricoles a l'écran , pas de mesage d'erreur mais rien ne se passe sur la carte.
J'appui sur le marteur en mode "debug" pareil une petite fenetre s'ouvre quelques millisecodnes puis se ferme et rien ne se passe sur la carte
La meme chose quand j'appui sur le marteau en mode "release".
Impossible d'injecter le programme sur ma carte.
forcement quelque chose doit m'echapper ou je dois mal faire , mais je ne sais pas où
Si une bonne âme peut me guider dans cette douloureuse épreuve de débutant se serait fort agréable.
Merci de ma'avoir lu
