Help with the Sleep Mode function,please (DSIC33EP..)

[celebriums]

Hi All

C code into "Sleep ();" Code and compile it, I get the following error. Could you help me? Please
Thank you.

Hi Benj
I hope your answer this questions. Thank you.

"Sleep mode is the lowest current-consumption state. The characteristics of Sleep mode include
the following:
Step 1.) The Primary Oscillator (POSC) and internal FRC oscillator are disabled..."

The compiler gives an error when I write the code as follows.
set_bit (FOSC,1);
set_bit (FOSC,0);

How do I set the FOSC?

Section 7. Oscillator
http://ww1.microchip.com/downloads/en/D ... 70580C.pdf (page7)

Note:
Setting OSCCON and RCON does not give an error.

9.2.2.1 SLEEP MODE
Sleep mode is the lowest current-consumption state. The characteristics of Sleep mode include
the following:

• The Primary Oscillator (POSC) and internal FRC oscillator are disabled

• The Secondary Oscillator (SOSC) continues to run if the Secondary Oscillator Enable bit
(LPOSCEN) in the Oscillator Control register (OSCCON<1>) is set. For details, refer to

Section 7. “Oscillator” (DS70580) in the “dsPIC33E/PIC24E Family Reference Manual”.

• The WDT, clock source and LPRC oscillator continue to run if the Watchdog Timer is
enabled. The WDT, if enabled, is automatically cleared prior to entering Sleep mode. For
details, see 9.3 “Watchdog Timer”.

• If the Voltage Regulator Standby Enable bit (VREGS) is cleared in the Reset Control
register (RCON<8>), the internal voltage regulator enters the Stand-by state. The voltage
regulator consumes a reduced amount of current in the Stand-by state.

• If the Flash Memory Voltage Regulator Stand-by Enable bit (VREGSF) in the Reset Control
register (RCON<11>) is cleared, the voltage regulator that powers the Flash memory
enters the Stand-by state. The Flash voltage regulator consumes a reduced amount of
current in the Stand-by state.

• The peripherals operating with the system clock are disabled

• The Fail-Safe Clock Monitor (FSCM) does not operate during Sleep mode, because the
system clock is disabled
To minimize current consumption in Sleep mode, do the following:

Ensure that I/O pins do not drive resistive loads

• Ensure that I/O pins configured as inputs are not floating

• Disable the SOSC

• Disable the WDT

• Enable the voltage regulator to enter Stand-by state in Sleep mode
When the device exits Sleep mode, it restarts with the current clock source as indicated by the Current
Clock Source Selection bits (COSC<2:0>) in the Oscillator Control register (OSCCON<14:12>).

Hi, to sleep, try something like this

Code: Select all

asm("PWRSAV #SLEEP_MODE");

Thank you for your answer LeighM.

Could you install and compile TTSTest2.fcfx which I installed?

The code you wrote is giving a error code.

[LeighM]

Hi,
I've just checked the header file for this device and found that the C function you need is Sleep(); not sleep();

Alternatively, it looks like the constants for SLEEP_MODE and IDLE_MODE are 0 and 1
