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.
Project is attached.
Solved! Go to Solution.

Willam Here is an example of the timer program it is running some where close to once a sec however I have not scoped it. It is also using a CY8C4247LQI-BLE-483 . It has a great example of the interrupt and clearing of it.

You need to clear the interrupt cause of the timer component. Depending on the timer base (UDB or TCPWM) there are different APIs.
There is a Timer_ClearInterrupt() or a Timer_ReadStatus(), check datasheet of your component.

If I understand your question correctly, yes. You just change the device to PSoC 4 BLE for the project

Many thanks guys, I added Timer_ClearInterrupt but still didn't work, but the example worked perfectly. Looked at my code a bit longer and threw it away and used the example. Excellent!
