Fixed point hysteresis filter for Arduino & Mbed
**_Type_** type can be:
- `uint8_t` or `int8_t`
- `uint16_t` or `int16_t`
- `uint32_t` or `int32_t` but only up to 23 bits
## Arduino example
Please see `examples` folder
## Mbed example
```cpp
#include "mbed.h"
#include "Hysteresis.h"
// Added samples (and result) will be initialised as uint8_t, hysteresis step 10
Hysteresis hysteresis(10);
int main() {
printf("result: 11 = %u\n", hysteresis.add(11)); // insert new number and get result
printf("result: 12 = %u\n", hysteresis.add(12)); // insert new number and get result
printf("result: 13 = %u\n", hysteresis.add(13)); // insert new number and get result
printf("result: 14 = %u\n", hysteresis.add(14)); // insert new number and get result
printf("result: 15 = %u\n", hysteresis.add(15)); // insert new number and get result
printf("result: 16 = %u\n", hysteresis.add(16)); // insert new number and get result
