Simple FPGA based Oscilloscope


Link to the project and bits, FPGA4FUN


Its a fun little project, the input stage is way too restrictive for it to be a really useful scope, however you could start pulling apart old analog scopes. I picked up the FlashyD with two inputs and the USB enabled version of the FPGA board, the Saxo.

Its a pity the site is mostly open sourceish except for a few of the more interesting projects, I did start to rewrite the scope control, if i finish it I’ll post it up..

I actually liked it better than the picoscope i tried, yes the picoscope can handle proper inputs but the speed and software was really poor. So for a DIY price ratio comparison the Saxo/Flashy can’t be beat.
