* usrp1: Add USB transport interfacesThomas Tsou2010-08-135-0/+192
| | | | | | | | | This patch adds generic interfaces for control and zero-copy transport of data between the host and a slave device. The interfaces are separate and generic to accommodate multiple implementations that may include cross platform libraries such as libusb or a platform specific implementation such as Linux usbfs.
* usrp1: Add SPI transaction command to FX2 firmwareThomas Tsou2010-08-134-3/+116
| | | | | | | | | | | | | | | | | | | | | | | | | | The existing SPI read command is set for half-duplex 8-bit or 16-bit writes followed by an equivalent sized read. This patch adds a new command, VRQ_SPI_TRANSACT, which performs a full-duplex transaction up to 4-bytes. Since the data buffer of the USB control transfer is not available for outbound data on IN requests, the 4 bytes of write data are sent through the request parameters. Enables are sent in the previsouly unused high byte of the length parameter. The USB field mappings are shown below. Only rising edge and MSB operation is supported. Field (8-bit) Description ===== ===== bmRequestType 0x80 (USB Device IN request) bRequest 0x83 (VRQ_SPI_TRANSACT) wValueH OUT data(0) wValueL OUT data(1) wIndexH OUT data(2) wIndexL OUT data(3) wLengthH SPI enables wLengthL Number of bytes to transfer (1-4) EP0BUF IN data
