ATK Explorer STM32F407 V3 BSP code borrowing workflow. When the current project needs a driver or peripheral that is not yet implemented, search the 60-experiment reference library, read the most relevant BSP source, adapt it to the current project (pin map, includes, Keil groups), or generate fresh code if no good match exists.
