Re: Best way to measure period between pulses? Counters and FPGA

I think Java is missing SPI maybe?

In general we try to make everything the same.

I am not sure if your comment implies more is available.
The FPGA code is there. It does not need to be edited.

The layer that most people write their code is only in the "User Code" layer. The layer below that is the "WPILib" layer. That is the layer that I mean that you need to edit if you want this functionality in that language. You may even be able to call into the FPGA interface layer directly from your user code if you call it at a time that it won't be overwritten by WPILib.
