Detailed Description
A Ticker is used to call a function at a recurring interval.
You can use as many seperate Ticker objects as you require.
Synchronization level: Interrupt safe
Example:
// Toggle the blinking led after 5 seconds #include "mbed.h" Ticker timer; DigitalOut led1(LED1); DigitalOut led2(LED2); int flip = 0; void attime() { flip = !flip; } int main() { timer.attach(&attime, 5); while(1) { if(flip == 0) { led1 = !led1; } else { led2 = !led2; } wait(0.2); } }
