Memory Usage library for Arduino AVR targets
This Arduino library prints memory usage on the Serial port.
Features
This library provides:
- Print memory usage on the serial console
- Get stack and heap size
- Get .data and .bss sections size

Print memory usage on serial port
void setup()
{
// Initialize serial port
Serial.begin(115200);
// Print memory usage
printMemoryUsage();
}Output serial port Arduino Uno
