FiFo. Combined with the front panel I/O ports this allows CAMAC operation and data taking without any PC or USB activity. All CC-USB logic is controlled by the XILINX Spartan 3 family FPGA. Upon power-up the FPGA boots from a flash memory. The configuration flash memory can be reprogrammed via the USB port, allowing convenient updates of the firmware. -

Page 8: Cc-Usb And Usb Driver Installation
2.1 Installation for Windows Operating Systems 1. Switch off the CAMAC crate and remove the power cord. Plug in the CC-USB on the far right slots (normally slot 24 & 25) and secure it with the front panel screw. Switch on the CAMAC crate. - Page 9 5. Select manual search for the driver 6. Type in the drive letter for the CD-ROM (e.g. D:, F:, …) and locate the file CC-USB.inf. Press Enter to select this driver and to close the window. 7. The WIENER CC-USB driver should be listed and highlighted in the driver list. The driver is not digitally signed which however does not have any effect on it’s functionality.
- Page 10 8. The “New Hardware Wizard” should copy all driver files into the Windows System32 folders and report a successful installation. WIENER, Plein & Baus GmbH www.wiener-d.com...

9. Run the XXUSBWin.exe program from the program directory or use one of the sample programming packages to communicate with the CC-USB. 2.2 Installation for Linux Operating Systems Linux provides a library libusb that allows to perform the bulk transfer to and from the CC- USB and VM-USB USB port. -

USB2 port of the CC-USB using bulk-transfer mode. Borrowing from the USB language, the buffers to be written to the CC-USB will be called Out Packets, and they are sent to pipe 0 of the USB port. The buffers to be read will be called In Packets, and they are read from pipe 2 of the USB port. -
Page 17: General Structure Of Out Packets
4.1 General structure of Out Packets Since internally, the USB controller of the CC-USB is set up as a 16-bit wide FIFO (First- In- First-Out Memory), the In and Out Packets are organized as collections of 16-bit words. For the purpose of the software, and more specifically, of the Windows Application Programming Interface (API) routines, the data are packed in byte-wide buffers, a process that may remain transparent to the user when proper set of routines (DLLs) is used. -
Page 18: Writing Data To The Camac Command Stacks And To The Naf Generator
The CAMAC NAF Generator (Address 8) is an internal module that interprets the information found either in the CAMAC Stacks (when CC-USB is in data acquiring mode) or in the Out Packet received from the USB port (when CC-USB is in interactive mode). - Page 19 Number of Product Terms – specifies the number of words in the stack that follow and that constitute bit masks for constructing a logical equation used in deciding whether the given operation is to be performed for the particular hit register data.

(up to 8192 bytes) compatible with the CC-USB functionality. Al data supplied by the CC-USB is to be read from the Endpoint 6. While reading, it is important to specify the length of the buffer not shorter than the length of the actual data buffer written by the CC-USB into this endpoint. - Page 21 CC-USB has dedicated 2kWords-long event FIFO to assemble events. To handle longer events, CC-USB splits the long event into parts, each of which appears as a separate event in the output buffer. The partial events are distinguishable by bit 12 of the Event Length word set, except for the last part.

CC-USB then formats the data read form the CAMAC bus and buffers them in a data buffer. When the buffer is full, CC-USB transfers its content to the In FIFO of the USB controller IC for a readout by host software. -
Page 23: Libxxusb Library For Windows And Linux
LIBXXUSB LIBRARY FOR WINDOWS AND LINUX A dedicated library of functions was developed to facilitate the utilization of CC-USB and its VME counterpart, VM-USB. This library is called libxxusb and requires the libusb0.sys driver to be installed. It is in fact a wrapper library for the general-use libusb-win32 library available via www.sourceforge.net... -

Page 25: Xxusb_Register_Write
The xxusb_register_read function first, sends a buffer to XX-USB, causing the latter to write the content of a desired register to its USB port FIFO and then, obtains the value by reading the buffer from the XX-USB.

Page 26: Xxusb_Stack_Write
On success, the function returns the number of bytes sent to XX-USB. The latter value is twice the length of the stack plus 2 (for a header word identifying a stack as a target). Function returns a negative number on a failure. Remarks WIENER, Plein & Baus GmbH www.wiener-d.com... -
Page 27: Xxusb_Stack_Read
The physical length of the regular stack is 768 16-bit words for CC-USB and 768 32-bit words for VM-USB. The physical length of the periodic (scaler) stack is 256 16-bit words for CC-USB and 256 32-bit words for VM-USB. While the stack is expected to contain properly encoded sequence of CAMAC (CC-USB) or VME (VM-USB) commands to be performed by XX-USB, it can store any sequence of numbers. -
Page 28: Xxusb_Usbfifo_Read
On success, the function returns the number of bytes read from XX-USB. The valid value is twice the number of 16-bit data words returned plus 2 (CC-USB) or 4(VM-USB). The latter “overhead” bytes contain event terminator word (0xFF for CC-USB, and 0xFFFF for VM- USB). -

Page 30: Xxusb_Bulk_Write
On success, the function returns the number of bytes read from XX-USB. Function returns a negative number on a failure, which in most cases signifies a timeout condition. Remarks The xxusb_usbfifo_read is given for the sake of completeness. WIENER, Plein & Baus GmbH www.wiener-d.com... -

256 on each consecutive call. The device must be in programming mode with the rotary selector in one of the 4 “P” positions. The configuration file of a XC3S200 FPGA of CC-USB will occupy 512 sectors of flash memory (512 calls to the xxusb_flashblock_program). The XC3S400 FPGA of VM-USB will occupy 830 sectors of flash memory.
