Some variants (marked with specific date codes) allow one-time programming of the reference current during IC manufacturing. This is used by large OEMs to lock a specific output current, preventing field adjustment. Verification here requires a dedicated programmer (e.g., Bright Power’s proprietary tool) to read the OTP status – a rare but critical step.

Demonstrates how to integrate this feature into the main application loop.

#include "config_manager.h"
#include "logger.h" // Hypothetical logging
SystemConfig_t g_sys_config;
void setup() 
// Initialize Config Manager
Config_Init();
// Attempt to load existing config
if (Config_Load(&g_sys_config)) 
    Log_Info("Configuration loaded successfully.");
    Log_Info("Brightness: %d", g_sys_config.brightness);
 else 
    Log_Warning("Config load failed or invalid. Loading defaults.");
    Config_SetDefaults(&g_sys_config);
    // Save the defaults immediately so the flash is initialized
    Config_Save(&g_sys_config);
// Apply settings to hardware
Hardware_SetBrightness(g_sys_config.brightness);


void loop() 
// Example: User changes brightness via button/UI
if (Button_Pressed()) 
g_sys_config.brightness = 100; // User sets to max
    // Save the change immediately
    if (Config_Save(&g_sys_config)) 
        Log_Info("Settings saved.");
     else 
        Log_Error("Failed to save settings!");

Some BYD Micro (比亚迪微) MCUs use “BF” or “BP” prefixes.

Programming these usually requires:

Without the exact datasheet, programming is not verified or safe – you risk bricking the chip. Some variants (marked with specific date codes) allow
