RP2040/2350 are IO monsters. You could for example make a logic analyzer that transfers logic data through ethernet.
This "very limited" microcontroller has two cores. Both of them can execute about 25 instructions per byte for generating "application-level traffic". You could definitely saturate a 100 Mbps connection with just one core.
- _flux 2y agoNow that you mention it, I think I would like to see a logic analyzer that does just that. No buffering, just straight up shovel the data to a mac address, or even IP address, and be done with it (maybe lose a few frames here and there). Let the PC worry about what to do with it, like triggers etc. Should be cheap, right? Though 1Gbit version might still be expensive..
- baby_souffle 2y agoHow is this different from the cheap salae clones now? Just sub out Ethernet for usb and that’s how they work now: a cheap ic with nothing but a2d and a usb phy samples and sends as fast as it can..
- _flux 2y agoIt would be over the network :), which is—I imagine—tiny bit simpler than over USB.
- eternityforest 2y agoCan't you do reads with very basic compression faster than most of these chips can push data to Ethernet?
