# Memory Usage library for Arduino AVR targets
[](https://travis-ci.org/Erriez/ErriezMemoryUsage)
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
## Examples
Arduino IDE | Examples | Erriez Memory Usage:
* [PrintMemoryUsage](https://github.com/Erriez/ErriezMemoryUsage/blob/master/examples/ErriezPrintMemoryUsage/ErriezPrintMemoryUsage.ino)
## Documentation
* [Doxygen online HTML](https://erriez.github.io/ErriezMemoryUsage)
* [Doxygen PDF](https://github.com/Erriez/ErriezMemoryUsage/raw/master/ErriezMemoryUsage.pdf)
### 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 RAM size
Get total on-chip SRAM size in Bytes:
```c++
unsigned int ramSize = getRamSize();
```
### Get free memory
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();
```
