Hey Gary I am newer to sensors and doing something similar using the Xilinx Spartan-3a instead of the Xilinx SP601. Is there any chance that you would be willing to share your VHDL code so I could compare it to mine because I am working on fixing the grouping problem as well?

How did this turn out? Curious about the DD2 interface turned out, as I’m about to attempt the same thing on a four layer board, at home. Thanks!

Hello Dan,
Thank you for sharing your project. I am just curious but what software are you using to draw those diagrams? They look nice!

Comment on Inferring true dual-port, dual-clock RAMs in Xilinx and Altera FPGAs by yogesh

How can one use “reset” implementation using the shared variable to clear the memory contents for the dual port?

Any chance of getting your simulator posted as well. I’m trying to work up something and just really not having any luck getting anything like reasonable results.

Excellent work, Dan. I was hooking up a VGA module to the JupiterACE from ZXGATE on the Papilio, got it to work but still have some sync problems — dual ported RAM will likely solve the issue. It’s nice to see that it’s possible to infer the BRAMs in a portable way, and also to read about some of the caveats.. Many thanks for the hours you put into this, and even more thanks for actually sharing it! :-)

Also, could you tell me where you got your FMC-LPC to SATA PCB fabricated?

thanks

This is really helpful for me as I am also trying to make FMC adapters for our application. It would be really nice if you can point me to the place where you got FMC-LPC library, I need the same for FMC-HPC connector that comes on Xilinx ML605 boards.

thanks

Comment on Brushless DC motor controller board by TC

Dan,

Thank you very much for posting your design! I was wondering if you had a partlist including the large capacitor at the input. I am trying to do the same thing but will be using NI’s RIO FPGA system as the controller to provide versatility thus I am just trying to replicate the driver portion. I think I have most of the components identified but want to make sure. In addition I am a ME with a slight background in circuitry but wasn’t sure of the reasoning for the C38 through C51 capacitors in parrallel vs using just one and how do you use the multiple signals to calculate the current?
