  1. …node. but BIO is ~15x less efficient per clock. RP2350 is capable of reading IOs at 400Mbps ( https://github.com/gusmanb/logicanalyzer ) and bitbanging at 800 Mbps (HSTX). From Bunnie writeup BIO needs 700MHz to do pedestrian 25Mhz SPI.

  3. >This means you have no easy way to do high-accuracy pulse time measurement is 2.5ns ( https://github.com/gusmanb/logicanalyzer ) to 3.3ns ( https://github.com/schlae/pico-dram-tester ) resolution not enough for you?

  6. …of the chip didn't run into the problem, and others could be solved with external resistors. Even https://github.com/gusmanb/logicanalyzer eventually found a nice RP2350 design. I think they didn't preannounce because it could have taken…
