Hi, glad to have this forum.
Simon worked with me to get the PicoProbe integrated and it has been working well. Some difficulties I am having are some of the libraries. I cannot figure out why they are not being found. I am unable to reach Simon by email at the moment so will do my best to post here and hopefully will get some answers. 

this is for Windows 10.

The RP2040 library has a lot of folders and some appear to be scanned and others are not. I have rescanned and set PATH and project folders to scan but still same problem. 

I have not been able to get the serial monitor to work and still cannot. I have errors in that it seems the serial monitor is not working in part because “strlen” in string.h is not declared it says. I also have other errors. See attached image.

All works otherwise in my basic tests now however still no serial monitor and am sure other errors will come up because these libraries are not found. I can add 20 library references I imagine, but some rp2040 work and some do not. “Api/itoa.h” works but “hardware/gpio.h” does not. They are at different levels in the library for localdata.

In print.h keeping serial monitor from getting input due to "strlen" not being defined yet string.h is right in the header.

My setup is Arduino 1.8, platform is the Earl RP2040 (PicoProbe), hardware Picoprobe with newest Vm version. I can upload and debug in my test sketch. 

Any help is appreciated.

Hello, yes it all compiles and builds ok. At least I dont see any outstanding errors. I have noticed it retains breakpoints even if I delete them but that is not a major issue at the moment. 

this is the error that likely is keeping serial monitor from working. "
Error (active)      E0020      identifier "strlen" is undefined      Stepper Control      res\rp2040\api\Print.h      52

Thank you,
I tried Build only before and the strlen looks the same as in the image above. it is not defined.

yes the baud rate is matching. that is engineering day 5 haha. 

With release it won't hit any breakpoints so that kinda defeats the purpose and serial is still not working. 

In Debug it hits breakpoints but will not execute the print command, from what I can see because it states strlen is not defined. 

being in my 40s and engineering for years I def tried these basics. I spent several years doing some work in visual Studio but am a bit rusty on all the settings now. However I think it should be working. Have tried all I can find.

why it is not scanning all the libraries? I think there are multiple issues happening. All those intellisense errors are pointing to libraries that cannot be found. 

Thanks for the help. Until i get this worked out I cant do much with this project but on Arduino IDE. its frustrating.

Thank you,
yes I understand. However I cant step beyond the strlen issue as it somes up with an error about a module missing or not loaded. something along those lines. Of course it compiles but that command is not executing. I agree it should not compile but it does and has an error. 

Attached is the txt file.

Thanks for the help.

HI thanks, ya i guess I see quoting a lot. my bad. not big deal.

ok I will get things back inline as this is where we need to be at this point. 
I did as you mentioned and attached some screenshots. the module not loaded comes up when using print or println. I suspect when this issue is resolved it may fix the other missing issues.

Interestingly, when setup runs, the println uses vsnprintf, and it appears it can't execute or locate that as well. However, it does not show red squiggly line below it. When I started VS2022, it gave me a pop up to search for the location of vsprintf when debugging. After that it just says module not loaded.   

While I can't find vsprintf on my C drive, I do show Windows SDK add on was installed back in 2020. Hopefully these hints help. 

thanks for the help.

HI, thanks for the explanation. 

Attached is the IDE of the basic example file I am using, and the print.h where the strlen is. The other vsprintf issue is from the print command in the setup function. I simply was trying both of them to see if any difference. 

Hi, yes it has been opened many times and nothing shows from the print or println commands. I changed the println to print just to see if that was the issue. I usually put the serial monitor on another screen, I have 4 of them. 

I cant ignore errors at least for the serial monitor because I still cannot get the serial monitor to work. I been trying to get something to work for debugging with the Pico and RP2040 library from Earl. If you don't have any solution I understand, maybe i can eventually find a way to get it working outside of Arduino IDE.

Thanks for the help.

Thanks, let me know if you all come up with something new. I will try some hail mary's here.

Hi, no it did not. Tried off / on, different combos. I will get back to this later today or tomorrow and try to figure it out with some hail mary's. i tried a lot before I reached out for help.

came across this. seems similar issue. 

"println also works for me in the Arduino IDE.

The code with println in it does seem to compile, even with the red underline. However, none output from any print commands, viz., print, println, printf, would produce output in the Serial Monitor." 

Although he seems to have fixed it but no idea how. I will try to change the com port tomorrow. 

This is from March.
