新手求教，如何使用enc28j60的驱动？？

发布于 2015-05-16 01:06:26 浏览：4678 订阅该版

我这个板子上只有enc28j60的网口，使用的硬件SPI1，我想启用这个这个设备。但是不行：启动信息，先是e0设备什么失败，查看device列表，后直接用enc28j60()然后就直接崩了。。

rtconfig.h配置：

同时问句？如何在去掉原来的dm9000驱动，，，直接删除那个文件？？还是在哪？

这家伙很懒，什么也没写！

现在我把SPI启动了，但是还是不行呀：

enc28j60的接的IO如图：[attach]2437[/attach]
初始化SPI的代码：

```

SPI1：
		GPIO_InitStructure.GPIO_Pin   = GPIO_Pin_5 | GPIO_Pin_6 | GPIO_Pin_7;
		GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
		GPIO_InitStructure.GPIO_Mode  = GPIO_Mode_AF_PP;
		GPIO_Init(GPIOA, &GPIO_InitStructure);
		//-----------------------------------------------------
		GPIO_PinRemapConfig(GPIO_Remap_SWJ_NoJTRST,ENABLE);
		GPIO_PinRemapConfig(GPIO_Remap_SWJ_JTAGDisable,ENABLE);
		//--------------------------------------------------------
		//remap spi1
		GPIO_PinRemapConfig(GPIO_Remap_SPI1, ENABLE);

stm32_spi_register(SPI1, &stm32_spi, "spi1");
CS脚及中断：
		GPIO_InitStructure.GPIO_Speed = GPIO_Speed_10MHz;
		GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;

/* spi21: PB6 */
		spi_cs.GPIOx = GPIOA;
		spi_cs.GPIO_Pin = GPIO_Pin_4;
		RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);

GPIO_InitStructure.GPIO_Pin = spi_cs.GPIO_Pin;
		GPIO_SetBits(spi_cs.GPIOx, spi_cs.GPIO_Pin);
		GPIO_Init(spi_cs.GPIOx, &GPIO_InitStructure);

rt_spi_bus_attach_device(&spi_device, "spi10", "spi1", (void*)&spi_cs);

/* Configure one bit for preemption priority */
		NVIC_PriorityGroupConfig(NVIC_PriorityGroup_1);
		GPIO_EXTILineConfig(GPIO_PortSourceGPIOC, GPIO_PinSource2);
		/* Configure ENC28J60 EXTI Line to generate an interrupt on falling edge */
		EXTI_InitStructure.EXTI_Line = EXTI_Line7;
		EXTI_InitStructure.EXTI_Mode = EXTI_Mode_Interrupt;
		EXTI_InitStructure.EXTI_Trigger = EXTI_Trigger_Falling;
		EXTI_InitStructure.EXTI_LineCmd = ENABLE;
		EXTI_Init(&EXTI_InitStructure);
		/* Enable the EXTI0 Interrupt */
		NVIC_InitStructure.NVIC_IRQChannel = EXTI9_5_IRQn;
		NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;
		NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;
		NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
		NVIC_Init(&NVIC_InitStructure);
调用：enc28j60_attach("spi10");

```
