Welcome to monitor_printf Discussions!

👋 Welcome!

This is a GitHub discussion for my Arduino monitor_printf library repository.

The purpose of the library is to make it easy to do printfs to the serial monitor in the Arduino IDE.

The library has a .h/.cpp file pair that define C++ class monitor_printf, which contains a begin() function to initialize some things, and a printf() function which works not by hooking into a device putchar function but rather by simply using vsnprintf() to print into a buffer, then using Serial.write() to write the buffer to the serial monitor. The buffer size is automatically expanded when necessary to print a longer string.

The library creates a single global instance of the class named the_monitor_printf, and then it #defines 'monitor' to be equal to that name. The #define is skipped if the user defines DONT_DEFINE_monitor before #including the .h file.
