[Icc-avr] Interrupt Help Please (Happy New Year)

[Andrew]

Hi john,

i should have read that section in the datahseet kinda sick of looking at it 
though.

my sleep function is now as follows and i still have the same probelm: -

void sleep(void)
{
DF_Deep_Power_Down(); // Put DataFlash one in deep sleep
DF_Deep_Power_Down_2 (); // Put DataFlash two in deep sleep

TCCR1B = 0x00; // Stop timer
TIMSK1 = 0x00; // Disable Timer Intterupts

DDRB = 0x00; // Tri-State PORTB
DDRC = 0x00; // Tri-State PORTC
DDRD = 0x00; // Tri-State PORTD
PORTB = 0x00; // Make Sure the port is not pulled-up
PORTC = 0x00; // Make Sure the port is not pulled-up
PORTD = 0x00; // Make Sure the port is not pulled-up

SPCR = 0x00; // Power Down the SPI
UCSRB = 0x00; // Power Down The USART

REGCR = 0x01; // Disable the USB Regulator
RTC_POWER_OFF // Turn the Power too the RTC OFF (PORTD4)

EICRA = 0x08; // Change INT1 Pin Interrupt to Falling Edge (INT1)

PRR1 = 0x81; // Turn Off the USB and USART using the power reduction 
register

SMCR = 0; // Clear SMCR Register
SMCR = 0x05; // Configure Sleep Register for Deep Sleep
asm("sleep"); // Put Processor into Deep Sleep

}



7.12uA in sleep -> when the USB has never been connected to the system

120uA sometimes goes to 490uA in sleep mode -> after the USB has been 
connected once.



I have no idea why my sleep function funcrtions this way i guess more 
datasheet reading joy, could just leave the sleep mode and get on with the 
rest of the code and go for a bigger batttery :)
