摘要：设计并实现了一个USB/EPP 转接系统，给出其硬件设计方案并讨论了相关技术细节， 使其实现USB 接口到EPP接口的相互数据转发。使仅具有EPP 接口的传统仪器设备借助于USB/EPP 转接系统拥有USB 总线所提供的即插即用和设备插架特性， 方便其通过USB 接口灵活接入同时拥有多个外设的计算机主机系统。关键词：USB；EPP；转 ...

Stantor is a Domotic project. It is a SCADA for the computer interface board K8055 (USB bus), K8000 (I2C bus) , X10 modules and also Webcam. It uses Browser WEB, I-mode and Wap2/Wap1, Apache,mySQL, PHP, javascript. It run with Linux 2.4 or 2.6 and XP

This application note describes a method for developing block-oriented I/O device drivers for applications that use the DSP/BIOS real-time kernel and includes examples that run with Code Composer Studio v2.1 on the Texas Instruments TMS320C5402 and TMS320C6711 DSP Starter Kits (DSKs). The device dri ...

//打开 USB 口读写, 由驱动程序的 Pipe 名确定 HANDLE hPipe = OpenMyDevPipe("MyPipe1") //驱动程序里面的 Pipe 名, 对应访问某个端点的 I/O, 这里我乱写的, 需要与驱动一致 if(hPipe != INVALID_HANDLE_VALUE) //打开 Pipe 成功 { ReadFile(hPipe, Buffer, BufSize, &nBytesRead, NULL) //从 hPipe 里读取数据到 Buff ...

i.mx27开发板的整套详细原理图，包括：DDR SDRAM, NAND FLASH, NOR FLASH, USB OTG, USB HOST,FEC PHY, UART,JTAG等等接口

Very simple USB 1.1 PHY. Includes all the goodies: serial/parallel conversion, bit stuffing/unstuffing, NRZI encoding decoding. Uses a simplified UTMI interface. Currently doesn t do any error checking in the RX section [should probably check for bit unstuffing errors]. Otherwise complete and fully ...
