CYPRESS SEMICONDUCTOR CORPORATION FX3 SDK SYNCHRONOUS SLAVE FIFO PROTOCOL EXAMPLE --------------------------------------- This example illustrates the configuration and usage of the GPIF II interface on the FX3 device to implement the synchronous slave FIFO protocol. A master device that implements the Cypress defined Sync Slave FIFO protocol is required to perform data transfers with this application. This application example does the following: 1. Configures the GPIF II interface to implement the Sync Slave FIFO protocol. 2. Enumerates as a vendor specific USB device with two bulk endpoints (1-OUT and 1-IN). 3. Create MANUAL DMA channels to enable the following data paths: a. All data received from the USB host through the 1-OUT endpoint is forwarded to the master device on the slave port through socket 3. b. All data received from the master device on the slave port through socket 0 is forwarded to the USB host through the 1-IN endpoint. 4. When any data packet is received through one of the ingress sockets, the application is notified and forwards the data to the recipient through a DMA callback function. Known limitation: In synchronous burst access operation, the minimum transfer size to perform data read/write accesses from/to the FX3 device should be three words. In 16-bit mode this is six bytes and 32-bit mode this is twelve bytes. To transfer data less than this, single cycle access operation needs to be used. Files: * cyfx_gcc_startup.S : Start-up code for the ARM-9 core on the FX3 device. This assembly source file follows the syntax for the GNU assembler. * cyfxslfifosync.h : C header file that defines constants used by this example implementation. Can be modified to select USB connection speed, endpoint numbers and properties etc. * cyfxslfifousbdscr.c : C source file that contains USB descriptors used by this example. VID and PID is defined in this file. * cyfxgpif_syncsf.h : C header file that contains the data required to configure the GPIF interface to implement the Sync. Slave FIFO protocol. * cyfxtx.c : C source file that provides ThreadX RTOS wrapper functions and other utilites required by the FX3 firmware library. * cyfxslfifosync.c : Main C source file that implements this example. * makefile : GNU make compliant build script for compiling this example.
