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

2个51单片机实现UART通信 程序分master和slave2个部分。 master等待按键(SW1),按键按下后将数据发送到slave单片机,slave单片机中断接受查询发送,将收到的数据发送回master,master中断接受,收到后将LED灯点亮。

A complete set of bit banged, software driven I2C routines I created for any PIC device - and they work!! These functions are single master only functions, and are ideal for communicating with things like EEPROMs, LCD Drivers, ADC Converters etc

The source code samples for chapter 2, 4, 6, and 8 are contained in the EvenChapters project. Those chapters all reference various aspects of this single project. The source code for the BullsEye control (chapter 10 example) is in the BullEyeCtl project. The source samples for the other chapters are provided in the Chapter XX sub-directories.

The LM158 series consists of two independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage.

This paper presents several low-latency mixed-timing FIFO (first-in–first-out) interfaces designs that interface systems on a chip working at different speeds. The connected systems can be either synchronous or asynchronous. The designs are then adapted to work between systems with very long interconnect delays, by migrating a single-clock solution by Carloni et al. (1999, 2000, and 2001) (for “latency-insensitive” protocols) to mixed-timing domains. The new designs can be made arbitrarily robust with regard to metastability and interface operating speeds. Initial simulations for both latency and throughput are promising.
