2.1.2、Verilog代码 Verilog代码分为3个模块:SPI驱动模块spi_drive、SPI读数据控制模块spi_read_ctrl和例化前面两个子模块的读数据顶层模块spi_read。 SPI驱动模块spi_drive:提供SPI模式0的读写驱动,具体可参见:FPGA实现的SPI协议(一)—-SPI驱动 SPI页写控制模块spi_page_program_ctrl:该模块使用一段式状态机编写...
most manufacturers are now based on the definition of Motorola to design. This paper is to use the Verilog hardware description language to write the SPI bus host module, the simulation of the ModelSim simulation waveform. According to the simulation waveform analysis, the design of SPI host modu...
You may use this VTREG in a simulation script. For example:signal void spi_func (void) { while (1) { wwatch (SPI_OUT); printf ("SPI_OUT: %2.2X\n", (unsigned) SPI_OUT); SPI_IN = SPI_OUT + 1; } } This signal function returns the SPI byte send plus 1 on the next SPI ...

SPI 全称为 Serial Peripheral Interface,译为串行外设接口。它是 Motorola公司推出的一种相对高速的同步、全双工的通信总线协议。 SPI 一般有以下几个特点: ◆ 因为时钟线的存在,SPI 是同步的串行通信总线。 ◆ 因为 Master 与 Slave 之间存在两根不同方向的数据线,所以 SPI 支持全双工传输。
