Nonetheless, the format specifiers we are going to use below are from the Arduino language (as can be seen here), so this tutorial should work on other Arduino compatible boards. The tests on the ESP32 were performed using a DFRobot’s ESP-WROOM-32 device integrated in a ESP32 FireBeetle board. The tests on the ESP8266 were performed on a DFRobot’s ESP8266 FireBeetle board. The code we are going to see below will be very short and simple but this functionality is very useful since many times we want to print bytes or numbers in different bases, such as for example MAC addresses or hash message digests. In this tutorial, we will check how we can print numbers to the serial port using different bases, more specifically in binary, octal and hexadecimal.

Note: all debug in setup must be debugA (always), due it is disabled now. if You want debug, just press any key and enter in monitor serial SerialDebug starts disabled and it only is enabled if have data avaliable in Serial #ifdef _AVR_ATmega32U4_ // Arduino AVR Leonardo Serial.begin(115200) // Can change it to 230400, if you dont use debugIsr* macros 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 ) ? Disable auto function name (good if your debug yet contains it) Disable SerialDebug debugger ? No more commands and features as functions and globals #define DEBUG_INITIAL_LEVEL DEBUG_LEVEL_VERBOSE Define the initial debug level here (uncomment to do it) For it just uncomment the DEBUG_DISABLED as nothing of SerialDebug is compiled, zero overhead :-) Disable all debug ? Good to release builds (production) printW(F('This is a warning - var ')) printI(F('This is a information - var ')) printV(F('This is a verbose - var ')) Library: SerialDebug - Improved serial debugging to Arduino, with simple software debugger You should see the following code: //////// The following figure shows the SerialDebugApp, companion app for SerialDebug library. This motivated me (João) to make a library for the Arduino IDE: the SerialDebug library, which enables debugging with levels and other functionalities.

However, we don’t have this feature on the Arduino IDE. The ESP-IDF has excellent debug output: the ESP-IDF logging, it has debug levels and displays the debug messages on your serial monitor with different colors accordingly to its level. Part 1 – Using debug with levels (currently reading).To show you all the useful features of the SerialDebug library and the SerialDebugApp, he created three tutorials dedicated to this subject: He also created a desktop application called SerialDebugApp that adds a UI and other useful functionalities. So, he created the SerialDebug library to bring better debugging to Arduino IDE. Warning: The developer of this tool is no longer updating this project, but the code is still available on GitHub.Īfter programming the ESP32 using ESP-IDF, João noticed that debugging for Arduino IDE needed some improvement.
