利用ARM的GPIO和SPI总线进行FPGA的被动串行配置,加载速度可以达到200KBytes/Sec.

SPI主发送数据，供FPGA接收对比解调效果使用，SPI接收端程序见 FPGA_SPI_recive_display.rar - SPI master transmit data for FPGA receiver demodulates effect using contrast, SPI slave program, see FPGA_SPI_recive_display.rar

STM32和FPGA通信，采用SPI的方式实现(Communication between STM32 and FPGA Implementation in the way of SPI)
