需要USB 2.0 的接口驱动:
I'm enquiry about the following USB project, and an
quotation for cost and release time:
1. An general USB 2.0 device that connects to an PC
and supports:
1.1 an data capture port to allow PC to read data into
PC memory at 64mbit/s
1.1.1 the port has 8 bit data, synchronized at rising
clock edge;
1.1.2 the clock is an master/external/input clock
6-30MHz
1.1.3 a data valid bit synchronized with clock cycle,
0/1=data shall be ignored/valid
1.1.4 data shall be save in a 256~1MB circular buffer
with maximum rate 8MB/S,
1.2 an general i/o port of 8~16 bits
1.2.1 maximum rate 50KB/s
1.3 USB power/reset output control
1.4 mimium hardware
1.4.1 if a programmable device like microprocessor is
used, all source of code needs to be supplied, we may
ask for further functionality in separate contract.
2. Windows Xp/2K drivers with source:
2.1 data capture driver with sample application to
save the captured data in PC memory and/or hard disk
2.2  data is continuous and shall not be losted no
matter which Windows application is running.
2.3 general I/O port driver, can write/read each port
bit
2.3 USB driver shall able to make use of maximum
allowed current of USB spec., say 0.5A
2.4 Driver for linux/uClinux may be required in future
3. If you believe an PCMCIA card can be used for above
funtions with little or no hardware chip, we may also
consider it
