Mascarade — STM32 & ARM Cortex-M Q&A

Description

Q&A bilingue (FR/EN) sur le firmware STM32 et ARM Cortex-M : drivers HAL/LL, CMSIS, FreeRTOS, peripherals (UART, SPI, I2C, DMA, ADC, timers), bare-metal register-level, et assembleur ARM Thumb-2. Couvre les familles STM32F0/F1/F4/F7/G0/G4/H7/L0/L4.

Ce dataset fait partie de la famille Mascarade, un corpus thématique destiné au fine-tuning LoRA de modèles compacts (cible : Gemma-3n-E4B et équivalents) pour des assistants spécialisés en électronique embarquée.

Format : JSONL « ShareGPT-style » avec un tour system (rôle d'expert), un tour human (question) et un tour gpt (réponse complète, code compilable, schémas ASCII si pertinent).
