How to debug Serial
Oct 6th, 2020 at 3:07pm
Print Post  
Tried to debug serial on Blue Pill connected via USB with STM32duino bootloader flashed.
First I try uploading in release mode. I chose Generic STM32F103C series, Variant ...128K (device has that).
Uploading works.

Then I switch to Debug. 
By magic the device is changed to Generic STM32F1 series, subdevice Blue Pill 103C 
and I can no longer chose Serial for Uploading.
Rather the Maple DFU bootloader (and other hardware devices) are offered.
So, shall one flash different bootloaders when switching from Release to debug?????

Thanks for the report.

Do you have the below option enabled?
vMicro > General > "Save Board, Port and Programmer for Each Configuration"

If yes, you will need to re-select the board, port and programmer when switching from Release Configuration to Debug Configuration for the first time.

Further information can be found on the Visual Micro Build Configurations Page.

You have the Debug set to Serial (vMicro > Debugger > Debug: Serial), if you change this to OFF it should build as expected.

If you are trying to use the Serial Debugger, it seems the vMicro > Debugger > Advanced ... > Remote Port has been set to "SerialUSB", which is not needed for the Blue Pill.

When I switch on Debug, but off debug:serial, it compiles, but a breakpoint is not being served.
No window for monitor digital pins. Vmicro just finishes.

Thanks, as you are trying to use the Serial Debugger, this will need to be set to Debug: Serial again.

Then ensure that the Advanced option shown in the previous post has not been set to SerialUSB.

Thanks, did so, but then:
VM_DBG.h: 73:28: fatal error: SoftwareSerial.h: No such file or directory
   #include <SoftwareSerial.h>
   compilation terminated
I found and scattered that library to several folders and restarted Studio.
Didn't help. Error:
VM_DBG.h:73: In file included from
Blink.ino: from
SoftwareSerial.h: 27:43: fatal error: circular_queue/circular_queue.h: No such file or directory
   #include "circular_queue/circular_queue.h"

The Software Serial Library isn't available in Roger Clark's STM32 core libraries, so isn't available to build for the debugger in this instance.

Do you have a user library installed for Software Serial it should be finding?

(The official Stm32duino core does however contain a version of the Software Serial Library, but it may be incompatible with the other core...)

Wow. It was a lot of work (the whole morning) to direct Arduino to the right Softwareserial library.
Maybe this is of interest to you also: Softwareserial for the Maple core
https://www.hackster.io/rayburne/color-barometric-extension-to-gps-date-time-clo...

By now Serial Debug is working when compiling in Release mode. 
The Debug mode throws error, is that being meant that way?

The digital pins being monitored are just those from the com port used for uploading.
How to see the digital pins from e.g. PC13 in the blink example?

Thanks for the information about the library, we will give it a go.

Can you attach the logs for compiling in Debug mode and in Release Mode so we can understand and compare further?

The digital pin monitor can be enabled from the vMicro > Debugger > Monitor Digital Pins option.

Please add screen shot of vMicro>Debugger menu when Release is selected and one when Debug is selected.

Thanks

Thanks and also a screen shot of the debug project properties for the one that fails like the one below.

So now you see the difference? The build error mentions serialUSB is unknown and for some reason you have entered it as a value.

Release compiles, Debug doesn't, recommends using Release.
The settings to get it working look little unexpected (Release, Debug:Serial?).

Anyway, is it possible to watch PC13?
void loop() {
  digitalWrite(PC13, HIGH);   // turn the LED on (HIGH is the voltage level)

Why set serial as local port when trying to use software serial?
Why post two unrelated screen shots?
Why have you not made your debug settings same as release which works?

Please only ask one question at a time so you can focus on the answer.

I think you have the capability to resolve by undoing the incorrect settings you have added.
