I'll help you create a feature for an using FMUV3 firmware (Betaflight target: MATEKF405 or similar F4 with 2MB flash). This feature will be a Blackbox logging manager with adaptive recording that optimizes flash storage. Feature: Adaptive Blackbox Manager for 2M Flash // File: src/main/drivers/adaptive_blackbox.c // Feature: Auto-manages 2MB flash with intelligent recording #include <stdbool.h> #include <stdint.h> #include "platform.h" #include "drivers/flash.h" #include "drivers/flash_m25p16.h" #include "drivers/time.h" #include "build/build_config.h" static flash_status_t flash_status
// Dynamic rate adjustment based on remaining space static uint8_t calculate_dynamic_rate(void) { if(!adaptive_bb_config.dynamic_rate) return 1;
// Implementation would scan flash for log headers // For brevity: erase first 512KB (oldest quarter) flash_erase_sector(0, 512 * 1024); uint8_t percent = flash_status.percent_used
return flash_status.free_bytes / bytes_per_second; }
