PSoc 4 BLe Timer problem

[Anonymous]

Hi, I'm using a '042-BLE' kit here and it's working fine. But I can't get a timer interrupt to work. Here is the main code:

   

 * ========================================
*/
#include <project.h>

   

 
uint16 ms_count = 0;
 
CY_ISR(MY_ISR)
    {
    ms_count++;
     
    if(ms_count == 1000)
        {               // 1 second
        LED_2_Write(!LED_2_Read()); // Toggle LED
        ms_count = 0; // reset ms counter
        }
    }
 
int main()
{
    Timer_Start(); // Configure and enable timer
    Timer_ISR_StartEx(MY_ISR); // Point to MY_ISR to carry out the interrupt sub-routine
    CyGlobalIntEnable; // Enable global interrupts
     
    for(;;)
    {
        // Infinite loop for timer/interrupt to keep executing
    }
}

   

The pin output is square running at 900us, not 1 second I had hoped for. Changing the clock frequency makes no difference.

   

This is going to be such a silly problem, I'm already embarrassed, but I've at this for some time and I can't see what is wrong.
