STM32 HAL固件库是Hardware Abstraction Layer的缩写，中文名称是：硬件抽象层。HAL库是ST公司为STM32的MCU最新推出的抽象层嵌入式软件，为更方便的实现跨STM32产品的最大可移植性。HAL库的推出，可以说ST也慢慢的抛弃了原来的标准固件库，这也使得很多老用户不满。但是HAL库推出的同时，也加入了很多第三方的中间件，有RTOS，USB，TCP / IP和图形等等。和标准库对比起来，STM32的HAL库更加的抽象，ST最终的目的是要实现在STM32系列MCU之间无缝移植，甚至在其他MCU也能实现快速移植。

Simulation can provide a lot of information about what the system is doing. We canadd the effect of different element, like Encoder resolution, ADC sampling rate, etc and understand how does it affect the system. Another benefit is the possibility to slow down the process, to gain insight on what happens of fast systems or, vice versa, speed up slow process.Because National Instruments is a unique company in the fact the we provide a fullhardware solution couple with a full development platform, we can use this tools in very particular ways For example, it is possible to combine the LabVIEW Control Design and Simulation Module along with the FPGA module to quickly prototype a controller. One of the main benefits of this approach is that there is no need to compile the FPGA code, which allows for a quick algorithm design turnaround and debugging.
