How it works
For now, see https://blog.spade-lang.org/quickscope/
How to test
Connect the thing with UART to uo[0] @ 115200 baud, then run the quickscope client. When ui[0] is
high, the logic analyzer will trigger and send the ui[0]..[7] and uio[0]..[7]
values to the host which will generate a .vcd file that can be viewed in
Surfer.
External hardware
You'll need a UART adapter and something to analyze
