Right external hardware is a recommended solution. You can then use the dios to do the transfer. It would operate much as flash camera, with a flash capture cycle then a download cycle From: Jim Ham <> To: Sent: Friday, July 29, 2011 4:30 PM Subject: Re: [ts-7000] Re: Using TS-7500 SBC to collect and transfer camera data over TCP/IP Now it's just a store and forward problem. If I were doing this I think
I'd use a PIC processor, some external static RAM and an FTDI parallel to USB chip. This way the camera/storage device can interface to anything with a USB A port on it. As long as the RAM is big enough and the average data rate doesn't overwhelm the USB connection it should work fine. The RAM can be set up as a huge circular buffer. You might even do this with one of Microchip's development boards so you wouldn't have to make a custom PCB. If the average data rate is not over 119200 baud you could even use an FTDI USB to serial device and the built-in serial port on the PIC. In my experience it's a _lot_ quicker to get a sequential logic device (i.e. microcontroller) going than an FPGA. BTW, I do this kind of thing for a living :-) Regards, Jim Ham mtrav100 wrote: > What if we only need to collect the data at 25 Mhz for a short > period of time. Essentially on a button press, we will collect data for , say, one second. Could we store said data in the onboard RAM or microSD and transfer it to the host computer over TCP/IP or USB for analysis once the 1 second sample is collected? > > > > ------------------------------------ > > Yahoo!
