PSoC 4 MCU

Hi. i have a question about Timer.

   

compared to other program, 'PSoC Creator' used wdt mostly by creating Timer.

   

but I think that side effect of this program could only 3 wdt.

   

but I want to use such as '1sec, 1min' Timer.

   

here's the example

   

***********************************************

   

SysTimer10ms++;
 if(!(SysTimer10ms%600)) { // 1 min
  SysTimerMin++;
 }
 if(!(SysTimer10ms%100)) { // 1 sec
  SysTimerForDHCP++;//DHCP LEASE TIME CHECK NO
 }
 if(!(SysTimer10ms%10)) { //100 ms
  SysTimer100ms++;
 }

   

***************************************************

   

 

   

please teach me in detail.

Using the systick timer or the WDT as you showed is the usual ARM M0 way. But in PSoCs (or PRoCs) is a bit more: there are components. Open the Topdesign view and drag a Timer Counter PWM - component onto your schematic screen. You may add a new page beforehand to better overview what you do. This component together with a clock component can be used to generate a one minute timer quite easy. The output can be connected to an isr component to get interrupted. With the component's APIs you are able to control (start/stop/reset etc) the TCPWM.
