Debugging Sketches

---

There are a few different resources that are available for debugging a sketch that isn’t working as intended.

When initializing a sketch, you can enable debug by calling pedal.init(true) instead of pedal.init(). This will put the pedal in “debug mode” which means it will send information to the Serial Monitor (Tools->Serial Monitor). Open the Serial Monitor before downloading your sketch. Once the sketch is running, you’ll see status info and any errors that were encountered while processing the routing information.

// Include our library of effects routines
#include <dreammakerfx.h> 

// Create/declare one echo effect and configure it
fx_delay my_echo_1(1000.0,   // 1 second echo
                   0.7);     // 0.7 feedback ratio

void setup() {

   pedal.init(MSG_INFO); // Initialize the system and display additional information

   // Connect our effect(s) to input and output jacks
   pedal.route_audio(pedal.instr_in, my_echo_1.input);
   pedal.route_audio(my_echo_1.output, pedal.amp_out);

   pedal.run(); // Run the effect

}

You can also generate a report of the final routing and parameters by adding a few additional commands before calling pedal.run(). print_instance_stack() will show you all of the instances in the sketch. print_routing_table() will show you how the audio and control are wired up. And print_param_tables() will show you the parameters for each instance.

// Include our library of effects routines
#include <dreammakerfx.h> 

// Create/declare one echo effect and configure it
fx_delay my_echo_1(1000.0,   // 1 second echo
                   0.7);     // 0.7 feedback ratio
 

void setup() {

   pedal.init(MSG_INFO); // Initialize the system

   // Connect our effect(s) to input and output jacks
   pedal.route_audio(pedal.instr_in, my_echo_1.input);
   pedal.route_audio(my_echo_1.output, pedal.amp_out)

   // Print debug info to Serial Monitor
   pedal.print_instance_stack();
   pedal.print_routing_table();
   pedal.print_param_tables();

   pedal.run(); // Run the effect

}
