I am having problems waking up from sleep/stop mode,I set the external pin in LLWU setting enabled and in the routine of detecting that interrupt set
Cpu_SetOperationMode(DOM_RUN, NULL, NULL); but I think the processor isn't detecting any interrupt. Also when entering the stop mode (VLLS) the board losses connection . All I need is a blinking led and via an external interrupt(falling edge) to set the processor in sleep and wake it up when rising edge on the interrupt is detected. I am using processor expert.
main looks like this :
int main(void)
{
/* Write your local variable definition here */
/*** Processor Expert internal initialization. DON'T REMOVE THIS CODE!!! ***/
PE_low_level_init();
EInt1_Enable();
Cpu_VLPModeEnable();
while(1){
Bit1_SetVal();WAIT1_Waitms(100);
Bit1_ClrVal();WAIT1_Waitms(100);
}
in events.c
void EInt1_OnInterrupt(void)
{
WAIT1_Waitms(100);
if (EInt1_GetVal())
{
Cpu_SetOperationMode(DOM_RUN, NULL, NULL);/* Write your code here ... */}
else {
Cpu_SetOperationMode(DOM_STOP, NULL, NULL);
}
}
Also tried this :
void Cpu_OnLLSWakeUpINT(void)
{
v = Cpu_SetOperationMode(DOM_RUN, NULL, NULL);// v is a char
Bit1_SetVal();WAIT1_Waitms(100);
Bit1_ClrVal();WAIT1_Waitms(100);// just to see if it is entering this function
}
This is my configuration of CPU
Hi Saliheberisha,
First, what debugger are you using? Some debuggers will lose connection when entering low power modes because the debug circuitry is turned off when you enter debug mode. Other debuggers will simply force the part to enter a pseudo low power mode. So in either case, it is not recommended to enter a low power mode when debugging.
Second, it sounds like maybe you are not handling ACKISO properly. Remember that Processor Expert does not handle this for you. So you will need to add some start-up code BEFORE the Processor Expert initialization runs. See the screenshot below.
Hope this helps,
Chris
