Three phase brushless motors (either AC induction or permanent magnet synchronous motors) historically owe their great success in adjustable speed application to the advent of frequency converters and sophisticated control techniques. These high-

基于SPI总线的ARM与FPGA通信实验，需要用到stm32和fpga-ARM and FPGA based on SPI bus communication experiment, the need to use stm32 and FPGA

FPGA作为从机与STM32的全双工通信，FPGA将接收到STM32的数据返回到STM32，Modelsim仿真和板子仿真都通过(Use FPGA as slave,realize the communication between FPGA and STM32. The function has been tested is no problem.)

迪文屏串口程序，自己写，可以移植,用于STM32F1xx系列ARM,可以方便移植使用。 (DWIN DGUS programm used to STM32F1xx.)((DWIN DGUS programm used to STM32F1xx.))
