String mStringLarge = "This is a large stringggggggggggggggggggggggggggggggggggggggggggggg" Ĭhar mCharArray = "This is a char array" Ĭhar mCharArrayLarge = "This is a large char arrayyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy" and before, comment the DEBUG_MININUM in SerialDebug.h - line 64 - Open Advanced/Avr example (this uses F() to reduce RAM usage), to especially to reduce program memory (flash) and for this, the default is mininum mode, If this error occurs, your board is a low memory board, #error "This is not for low memoy boards, please use the basic example" Good for low memory, due use flash, but more slow and not use macros Disable native Serial.printf (if have) Force debug messages to can use flash ) ? #define DEBUG_INITIAL_LEVEL DEBUG_LEVEL_VERBOSE Define the initial debug level here (uncomment to do it) For it, each module must have a TAG variable: Disable SerialDebug debugger ? No more commands and features as functions and globals For it just uncomment the DEBUG_DISABLED as nothing of SerialDebug is compiled, zero overhead :-) Disable all debug ? Good to release builds (production) If want or need, please open the example in Directory Avr. and RAM memory is much faster than Flash memory Note: this version is for Espressif or ARM boards, debugE("This is a error - var %d", var) debugW("This is a warning - var %d", var) debugI("This is a information - var %d", var) debugD("This is a debug - var %d", var) debugV("This is a verbose - var %d", var)

Library: SerialDebug - Improved serial debugging to Arduino, with simple software debugger

Or Others for Arduino as Due, MKR, Teensy, Esp8266 and Esp32. For this post, we use ESP32 board and the example in the “Others” directory. Then select Avr for Arduino with AVR arch, like Uno, Leonardo and Mega. In the File menu, select Examples > SerialDebug > SerialDebug_Advanced.

How to use Simple Software Debuggerįirst, follow the steps in Part 1 of this series to install SerialDebug library. But you can try the debugger with this board by disabling DEBUG_MINIMUM mode, just comment line 64 of SerialDebug.h. Note: due to program memory limitations, the simple software debugger doesn’t run in low memory boards such as Arduino Uno. Add or change watches for global variables (works only if debugger is enabled).Show and change values of global variables (works only if debugger is enabled).Call a function (works if debugger is enabled or disabled).Debugger: It is a debugger, you can send commands in the Serial Monitor such as:.For this reason, this feature in SerialDebug library starts disabled until receiving the command “dbg”. But it is optimized to reduce memory and overhead of processing. Software: It’s implemented in software, not in hardware as a real hardware debugger.

It doesn’t have all features of a real hardware debugger (like the ability to run code step by step).

Simple: It’s a simple, but functional debugger.

Let’s take a closer look at its features: The SerialDebug library has a simple software debugger. When I was developing SerialDebug library, I thought how to bring some hardware debugger features to Arduino without the need for extra hardware and skills. Most of all debugging in Arduino IDE is done with Serial.print commands. That’s why there are such few people using debugger in Arduino IDE. There are simpler solutions, but these are not free, like the MicroStudio.

Another IDE (Eclipse, Atmel studio, etc).

An external hardware (JTAG, Atmel-Ice, etc).

If you’d like to use hardware debugger, you need: However, until now Arduino IDE doesn’t support hardware debugger. This is a great solution for debugging because I can see the value of variables, set breakpoints (up to 2 for ESP32), run code step by step, and more.

When I (João) was developing in ESP-IDF (ESP32 native SDK), I used an hardware debugger, using external hardware compatible with JTAG, GDB server and Eclipse CDT.

Part 2 – Simple Software Debugger (currently reading).

You can check all the articles on the links below.

This is part 2 of a series of articles about the SerialDebug library. In this article he’ll show you how to use the simple software debugger of the SerialDebug library that has most functionalities of an hardware debugger. The SerialDebug library created by João Lopes allows you to improve debugging for the Arduino IDE. This tutorial was written by João Lopes and edited by Sara Santos.
