# Embedded Linux Timer API
Library is a High-Level POSIX TIMER API.
## API Functions
#### Define Timer Signal
```c
#define TIMER_SIGNAL_1 SIGRTMIN + 1
```
#### Allocate Memory
```c
timerValues_t *timer1 = (timerValues_t *)malloc(sizeof(timerValues_t));
```
#### Timer Initalize
```c
timerInit(timer1,TIMER_SIGNAL_1,timerCallback_1);
```
| Parameter | Type | Description |
| :-------- | :------- | :------------------------- |
| `Name` | `timer_t` | Timer Name |
| `Signal` | `uint16_t` | Timer Signal|
| `Callback ` | `void *` | Timer Callback Functions |
#### Timer Start
```c
timerStart(timer1, 0 , 1000 ); -> 1second Periodic Timer
timerStart(timer1, 1000, 1000 ); -> 1second Periodic Timer
timerStart(timer1, 3000, 0 ); -> 3second One Shot Timer
```
| Parameter | Type | Description |
| :-------- | :------- | :------------------------- |
| `Name` | `timer_t` | Timer Name |
| `Time_Ms` | `uint16_t` | One Shot Timer Value (ms)|
| `Time_Ms ` | `uint16_t ` | Periodic Timer Value (ms) |
#### Timer Stop
```c
timerStop(timer1);
```
| Parameter | Type | Description |
| :-------- | :------- | :------------------------- |
| `Name` | `timer_t` | Timer Name |
#### Timer Deinit
```c
timerDeinit(timer1);
```
| Parameter | Type | Description |
| :-------- | :------- | :------------------------- |
| `Name` | `timer_t` | Timer Name |
#### Timer Callback Function
```c
void timerCallback_1(int signal)
{
//(void)signal;
printf("Timer Interrupt %d ------------\n",signal);
}
```
