How to wake Pic32 from sleep mode?
I am trying to keep PIC32 in sleep mode on boot up. And when the power button is pressed the Pic32 should exit the sleep mode and wake up.
I am able to put PIC32 in sleep mode but I am not sure how I can trigger it to wake up on button press.
Is it possible if I can trigger an interrupt whenever the user presses the power button and thus wake the PIC32?
I am using microchip harmony framework and am quite new to this can someone please suggest how I can achieve this?
To put PIC32 I am using the PowerEnterMode function of harmony. To wake up PIC32 I have tried using the watch dog timer following the sample project provided with microchip harmony but couldn't get it to work.
I also read that I can use external interrupt to set it up but I don't know how to set it up.
I have added my code below.
void APP_Initialize ( void )
{
DRV_ADC_Open();
DRV_ADC_Start();
PLIB_ADC_Enable(ADC_ID_1);
SPIHandle = DRV_SPI_Open(DRV_SPI_INDEX_0, DRV_IO_INTENT_READWRITE );
DelayMs(100);
SYS_DEVCON_PowerModeEnter(SYS_POWER_MODE_IDLE);
appData.state = APP_STATE_POWER_UP;
}
void APP_Tasks (void)
{
switch ( appData.state )
{
case APP_STATE_POWER_UP:
{
uint8_t pwrButton;
pwrButton = PWR_BTNStateGet() ;
if (npwrButton == 0) // If button is pressed
{
PwrButtonDebounce += 1; // Increment the pressed timer
DelayMs(10);
} else
{
PwrButtonDebounce = 0; // Clear the Debounce Timer
}
if (PwrButtonDebounce == MAX_DEBOUNCE) // Debounced....
{
// Here Wake up routine on button press
appData.state = APP_STATE_INIT;
}
}
}
I expect that whenever I press the power button the Pic32 should come in the APP_STATE_POWER_UP state and on debounce go in the initialization state but It never comes in this state.
Can someone suggest how I can set this up?

You should use Change Notification interrupt.
Enable the CN interrupt on the pin that you have your button and it will wake your device when pressed.
