zynq中spi的配置

二、实际使用引脚

三、引脚分配

set_property 	PACKAGE_PIN 	AC11 			[get_ports emio_spi0_m_i_0]
set_property 	PACKAGE_PIN 	M8 				[get_ports emio_spi0_m_o_0]
set_property 	PACKAGE_PIN 	P9				[get_ports emio_spi0_sclk_o_0]
set_property 	PACKAGE_PIN 	B13				[get_ports spi_tx_ss_io]
set_property 	IOSTANDARD 		LVCMOS33 		[get_ports emio_spi0_m_i_0]
set_property 	IOSTANDARD 		LVCMOS33		[get_ports emio_spi0_m_o_0]
set_property 	IOSTANDARD 		LVCMOS33 		[get_ports emio_spi0_sclk_o_0]
set_property 	IOSTANDARD 		LVCMOS33 		[get_ports spi_tx_ss_io]

四、vitis初始化

XSpiPs SpiInstance;
int SpiPs_Init(XSpiPs *SpiInstancePtr,u16 SpiDeviceId )
{int Status;XSpiPs_Config *SpiConfig;/** Initialize the SPI driver so that it's
