Personnal experience
Microcontrôleurs	Microcontrôleurs Le but de ce projet est de prendre en main les microcontrôleurs STM32 (80MHz) et ESP32 (240MHz). L'exercice consiste à implémenter un horodateur d'évènements sur le STM32. On prévoit deux lignes d'entrée indépendantes capables d'horodater des front montant ou descendant sur la même base de temps. Les horodatages, précis à 12.5ns, sont encodés en entiers 32 bits et envoyés dans un packet UDP sur le réseau. On utilise un W5500 interfacé en SPI avec le STM32 pour envoyer ces paquets. On utilise d'abord la connection série pour renvoyer les statistiques sur les pulses détectés (moyenne, minimum et maximum de période). Puis, on utilise le système d'IRQ pour horodater les pulses. On utilise ensuite le transfert DMA pour envoyer les statistiques par connexion série UART. Enfin, on ajoute le W5500 par connection SPI avec transfert DMA pour envoyer les horodatages sur le réseau. Dans ce système, le ESP32 est utilisé comme générateur de pulses. Une API web est développée pour lancer l'émission d'un nombre de pulse spécifique à une fréquence donnée. Le dépôt de ce projet est à cette url esp32-pulse-emitter. Le code du STM32 est disponible à cette url : stm32-pulse-timestamper. On attends des fréquence de train de pulses de l'ordre de qques 10aine de kHz en émission et en lecture. Microcontrôleurs Prise en main du microcontrôleur STM32 : compréhension de la documentation, utilisation des fonctions bas niveau pour exploiter le DMA, implémentation efficace de la demande initiale d'horodatage de pulses, un dépôt de source : stm32-pulse-timestamper Prise en main du microcontrôleur ESP32 : compréhension de la documentation, Mise en place de tâches temps réel, implémentation de fonction de gestion de requêtes HTTP GET et POST, implémentation de la demande initiale de génération de pulses, un dépôt de source : esp32-pulse-emitter Au final : un horodateur d'évènement base sur une STM32 capable de détecter, d'horodater à 12.5ns près des pulses émis à une fréquence de quelques 10kHz et de transmettre les horodatages sur le réseau et un générateur témoin basé sur un ESP32 capable de générer des pulses à 500kHz.
