The STM32F40x/41x/427/437/429/439/401/411xE DSP and Standard Peripherals Library is a complete package， consisting of device drivers for all of the standard device peripherals， for STM32F405xx/407xx， STM32F415xx/417xx， STM32F427xx/437xx， STM32F429xx/439xx， STM32F401xx， STM32F411xE andSTM32F446xx devices 32-bit Flash microcontrollers.

　　This library is a firmware package which contains a collection of routines， data structures and macros covering the features of STM32F40xxx/41xxx/

　　427xx/437xx/429xx/439xx/401xx/411xE/446xx peripherals. It includes a description of the device drivers plus a set of examples for each peripheral. The firmware library allows any device to be used in the user application without the need for in-depth study of each peripheral’s specifications.

　　This Library contains also the CMSIS DSP Software Library， which feature a suite of common signal processing functions for use on Cortex-M processor based devices. The library is completely written in C and is fully CMSIS compliant. High performance is achieved through maximum use of Cortex-M4F intrinsics. For more details， please refer to CMSIS DSP Software Library

　　Using the Standard Peripherals Library has two advantages： it saves significant time that would otherwise be spent in coding， while simultaneously reducing application development and integration costs.

　　The STM32F40x/41x/427/437/429/439/401/411xE DSP and Standard Peripherals Library is full CMSIS compliant.
