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. 

Micro1 out..

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.

Hi, yes I understand merely trying to find a solution.

Yes serial works fine in Arduino although I have no used it in a while. It worked last time I was in it. I am aware about setup and loop. those are simplified loops and setup to make it easier to code for people. 

I see a delay in there about 5000. you can see it on one of my posts I think of the IDE.

Pico makes the port when you hold down bootloader and short some pins. That part works. I also can use pico in Arduino, just not in Picoprobe mode.

I have not had time to day to work on it but will try to.

Hi, I tested in arduino IDE. I had to use a different file although same code. I cant get Picoprobe working on arduino IDE just he regular Earl RP2040 library. But you can see it works. Have not done more testing in VS2022 but will try to today.

Please try the attached simple project (we have tested on v2.0.2 of the board package), and we found the delay(1) seemed to lock up the board after the first button press, hence it being extended in our very simple example.

This was tested with:
Debug: Off
Board: Raspberry Pi Pico (Picoprobe)
DTR + RTS Enabled on Serial Monitor

As you have both the Pico board, and PicoProbe board connected via USB, there will be two serial ports presented.  Make sure the one for the Pico is selected when both are connected via USB.

It is also worth ensuring the Serial lines are not connected between the Pico and the Pico Probe.  If they are please let us know as this will forward the serial traffic through the PicoProbe board as well.

Note: The same sketch worked fine in the Arduino IDE as well, with the same board selected, and both boards connected via USB.

Hi, Ok I have tested it. I dont have both serial connected because one will be a host USB when I get this to the point where I can write code and test it. Thus It is only going through the pico probe Com 9. 

So far no success. Release, Debug, Debug off, Debug on same thing, nada. Release won't compile so that 

the breaks will hit in Debug mode so I can verify that. I assume the code is getting loaded onto the board. I have tried different combinations. Should I try to uninstall my previous OpenOCD and GDB or.. whatever all that other stuff I put in to get PicoProbe to work on Ard IDE that never did? Maybe it is getting in the way. I do not think it is the COM port as 6 did work on Ard IDE. If you can get it to work must be something in my system not connecting to VS. 

Soo I changed the library to just Earls Ras Pi Pico so am plugged into COM 10 direct to the target not through PicoProbe and with Debug off I GET SERIAL OUTPUT! yeah!

SOO its something on the PicoProbe side. 

Hope that gives you some ideas. 

Hi, I can't seem to get instance of Serial to be used as Serial1. can you help me with some code?

Hi, yes i tried that in the past also. No Success.

Hi, here is the output with Serial1 in the sketch and Serial1 for the RP2040 settings as the Serial to use. 

it will not let me attach a file anymore here. so here it is.

edited.. ok emailed text file to you.

If you change the board options to match the defaults below it should resolve this error:
Debug Port: Disabled
Debug Level: None

These debug options are for logging from the core itself which is unrelated to vMicro Serial / Hardware debugging functionality.

What happens if you set it to Disabled and None as suggested in the previous post?

Simon and Tim have been very helpful. As I had torn the wiring out and rewired it I did lack the UART0 wires. I had gotten distracted and forgot to add them back in. However it still was not working even this morning.

I finally updated the test code from Simon to be Serial1 and the RP2040 options to use Serial for debugging, not Serial1 or Serial2, and suddenly it started working. Looks like a combination of things. Anything can mess up these systems so it all has to be right to work.

Thanks again!

Your email address is not visible to other users, your identity is hidden. The title of this thread was also changed from "Can't find some libraries" to be more relevant.

There is not doubt that your project is excellent and complex. However, the wiring issue could have been found and tested with a simple sketch/program that writes to serial.

There can be many valid reasons why libraries can't be found or serial does not print. You can see how many views there have been of the 3 pages of this thread, many. It is important for the forum to provide clear questions and answers for users. 

That isn't always an easy task. In this case, it is important for users reading this thread to ignore all the conversation except for the wiring issue.

A wiring issue does not reflect badly on you. Many users would not be ready to take the steps you have to use a probe in a complex project. It is appreciated if you keep things as simple as possible. We don't charge enough to cater for anything else.

Thanks for posting.
