Printing log statements:

enable debug logging by uncommenting this line DaisySeedProjects/Software/GuitarPedal/guitar_pedal.cpp at main · bkshepherd/DaisySeedProjects · GitHub
If you want to print floats you can temporarily add this to the makefile: LDFLAGS += -u _printf_float Lost half day on figuring out how to debug/ print floats :/
Add your print statements
Run and connect with serial monitor, I use this Serial Monitor - Visual Studio Marketplace

Additionally, you could also put the tap tempo on the UI if you have a screen

The code used to print the CPU should be a good example of that and you could just pop it into your effects DrawUI (or even the base_effect_module itself)

github.com/bkshepherd/DaisySeedProjects

Software/GuitarPedal/Effect-Modules/base_effect_module.cpp

main


      
          
                      rightArrowRect = rightArrowRect.Reduced(0, 1);
                      if (rightArrowRect.IsEmpty())
                          break;
                  }
              }
          
              display.WriteStringAligned(m_name, Font_11x18, topRowRect, Alignment::centered, true);
              display.WriteStringAligned("...", Font_11x18, boundsToDrawIn, Alignment::centered, true);
          
              if (showCPU) {
                  char cpuStr[64];
                  sprintf(cpuStr, FLT_FMT(3), FLT_VAR3(GetCPUUsage()));
                  display.WriteStringAligned(cpuStr, Font_11x18, boundsToDrawIn, Alignment::bottomCentered, true);
              }
          }

This also shows how you can format floats for printing WITHOUT needing the above flags/configuration

Edit: Also because I had posted 3 times in a row before I was unable to post a 4th time a few days ago when something came up I wanted to post here, so in a way you freed me, thank you
