Description: 本驱动程序在linux2.6.17中测试通过。yangxing msn:lelma_yx@hotmail.com
希望对SPI操作的朋友有所帮助。
一、工作方式：
从设备：SPI为MASTER模式
S3C2410：SPI为SLAVE模式＋DMA
二、工作流程
1.S3C2410从接收：当从设备发送数据时，S3C2410利用DMA方式收数，收到指定长度的数据，则进入DMA中断，将接收的数据拷出。
2.S3C2410从发送：当S3C2410需要发送，首先由RTS请求发送，然后等待从设备应答CTS，当从设备应答CTS时，进入外部中断，启动DMA发送，发送完成，再次进入从接收状态。
三、文件位置
spi_dma_slave.c
spi_dma_slave.h
circular_buf.c
circular_buf.h
等文件存放入driver/char/目录
dma.c存放于arch/arm/mach-s3c2410/目录
dma.h存放于include/arm-asm/mach-s3c2410/目录
四、使用环境
1.arm-linux-gcc-3.4.1-the driver linux2.6.17 in which the test. Yangxing msn : lelma_yx@hotmail.com hope to operate SPI friends help. 1, mode of work : from equipment : SPI for the S3C2410 MASTER mode : SPI for SLAVE + DMA mode 2, workflow 1.S3C2410 from receiving : When sending data from the device, using DMA S3C2410 debt, the length of the designated data DMA will enter the interruption will receive unfettered access to the data. 2.S3C2410 from this : When S3C2410 need this, the first request sent by the RTS, Then wait for the response from CTS equipment, when the equipment response from CTS, access to external interrupt start DMA sent, Send completed, re-entered, from receiving state. 3.

Description: S3C2410的串行外设接口SPI可以进行串行数据传输接口。S3C2410具有两个SPI，每个SPI具有两个8位移位寄存器用于独立地发送和接收数据。在SPI传输过程中，数据时同时发送和接收的(全双工)，8位串行数据传输频率由相应的控制寄存器设置，如果希望仅发送数据，则接收数据can be dummy，同样如果只希望接收数据，则应该发送dummy 1 data。
有4个与SPI传输相关的引脚：SCK (SPICLK0,1)、MISO (SPIMISO0,1)数据线、MOSI (SPIMOSI0,1) 数据线、SS (nSS0,1)-低电平有效。
特性
— SPI 2.11版协议兼容
— 8位发送移位寄存器
— 8位接收移位寄存器
— 8位预定标器逻辑
