This Arduino library prints memory usage on the Serial port.

Features

This library provides:

Examples

Arduino IDE | Examples | Erriez Memory Usage:

### Print memory usage on serial port

{c++}
void setup()
{
  // Initialize serial port
  Serial.begin(115200);
  // Print memory usage
  printMemoryUsage();
}

#### Output serial port Arduino Uno

{c++}
SRAM size:  2048 Bytes
.data size: 22 Bytes
.bss size:  170 Bytes
Stack size: 2 Bytes
Heap size:  0 Bytes
Free mem:   1854 Bytes

Get total on-chip SRAM size in Bytes:

{c++}

unsigned int ramSize = getRamSize();

Get free memory size which can be allocated between stack and heap:

{c++}

unsigned int freeMemSize = getFreeMemSize();

### Get stack size

{c++}

unsigned int stackSize = getStackSize();

### Get heap size

{c++}

unsigned int heapSize = getHeapSize();

### Get .data section size

{c++}

unsigned int dataSize = getDataSectionSize();

### Get .bss section size

{c++}

unsigned int bssSize = getBssSectionSize();
