The Pico-Ice is a circuit board with an Rp2040 and an FPGA.
The RP2040 runs ueForth.
I am building a Mecrisp-Ice J1 on the fpga, but I need to debug it. A good way is to run signals out, maybe through a logic analyzer. Better yet, out to the RP2040. There is even PIO software on the RP2040 to implement a logic analyzer.

Of course the bandwidth through the USB to the host is limited, but one can analyze the data directly on the RP2040 using uEForth.
Better yet, the RP2040 can provide fast feedback to the FPGA.
This is clearly not a bug with uEForth, but I know that Brad is interested in integrating with the FPGA, so I am posting this here. If you want to join the discussion of this topic, here is an invite to the channel.
