Ralph[m]: > <@rursprung:matrix.org> i have a question about probes: > so far i've always used STM32 nucleo boards or arduino uno boards where i didn't need a separate probe. recently i've now bought an RPi Pico W which you can flash without a probe but you can't debug it without one (and thus also no RTT output; though i guess i could just let defmt print to serial and read that via USB - i'd just have to flash + read separately and probably miss the first log entries since the device reboots after flashing and uses the USB port for file transfer during flashing?). > > i also thought about buying an ESP32-C6 (just as with the RPi Pico: i have no reason to buy one, i just thought it might be nice to have one lying around to play around with it at some point 😅). > > now i'm wondering what i should do in terms of probes: should i just get a 2nd RPi Pico and use that as a probe (either with picoprobe or with the source of the probe-rs one)? or should i get the one from probe-rs? what would be the advantage of the latter? > and how do you do it with the probe connector for the RPi Pico? i (accidentally) bought the board without headers and have now soldered the normal headers to it but not yet a connector for the three probe pins - i can either solder a normal header there (to connect with jumper wires) or [this header](https://www.digikey.ch/en/products/detail/jst-sales-america-inc/BM03B-SRSS-TBT/1828498), though i'm not sure where to then find a matching cable (esp. in case i'd just get a 2nd RPi Pico - then i'd need a cable with this connector on one end and normal pins on the other?) > > do you have any recommendations? > > note: this is for private DIY projects, so i'm not looking for an expensive probe (though i'm also not sure which advantages are more expensive probe would have?). Not directly answering your question, but you mentioned esp32c6 so just as an FYI it has a USB probe built-in which you can use out of the box with probe-rs, no external hw required
