monsonite Posted August 19, 2015 Report Share Posted August 19, 2015 Hi All, I am about to commence a design for a high speed flash converter - similar to this one http://www.knjn.com/docs/KNJN%20Flashy%20boards.pdf These are based on the TI ADC08200 - a 200 MSPs converter. I am proposing to put it onto a 16 bit wing sized board with some other analogue circuitry This would open up the ability for a 100MHz bandwidth Papilio scope project using ZPUino - outputting 800x600 VGA. Has anyone in the forum used this part, or have any FPGA scope experience? Is this something that has already been covered? regards Ken Quote Link to comment Share on other sites More sharing options...

Jack Gassett Posted August 27, 2015 Report Share Posted August 27, 2015 Hello Ken, There is the OpenADC board too that has been made to work with the Papilio:http://newae.com/openadc At one point I was very interested in making a FPGA OScope project and I think I studied the Flashy board to get some ideas. Unfortunately I never went beyond the research phase. Oh, Ian Lesnet at Dangerous Prototypes did a very nice writeup of an FPGA Analog board that has some good info... Also, The OLS software actually has an Analog mode that you can use for the initial software to use for testing... Jack. Quote Link to comment Share on other sites More sharing options...
monsonite Posted August 27, 2015 Author Report Share Posted August 27, 2015 Hi Jack Thanks for the openADC link - much appreciated. I have met Ian Lesnet a couple of times both London and at the OHS in NYC in 2011. A successful day - I wrote my first baremetal VHDL to control the LEDs and read the switches on the Papilio DUO/Logistart shield. I found VHDL has a steep learning curve, and the Xilinx ISE took 6 hours to load -- but I thought if I started at the bottom, I'll get up there one day Thanks again for a great, versatile little dev-board.
