Sleep mode ADUCM3029

Hi EZ,

 

I am currently working on an embedded project which use a ADUCM3029 microprocessor, and I need to save as much current as possible, that is why I am using the function provide by ADI : adi_pwr_EnterLowPowerMode().

 

It exist 4 sleep mode according to the datasheet : 

 

 ADI_PWR_MODE_ACTIVE = 0 << BITP_PMG_PWRMOD_MODE,
 /*! Core Sleep power-down mode */
 ADI_PWR_MODE_FLEXI = 1 << BITP_PMG_PWRMOD_MODE,
 /*! Full Hybernate power-down mode */
 ADI_PWR_MODE_HIBERNATE = 2 << BITP_PMG_PWRMOD_MODE,
 /*! System Sleep power-down mode */
 ADI_PWR_MODE_SHUTDOWN = 3 << BITP_PMG_PWRMOD_MODE

 

I am currently using the ADI_PWR_MODE_HIBERNATE, to put the microcontroler in a sleep state, and when there is an interupt which came from the GPIO, it wake up the cheap, with the function : adi_pwr_ExitLowPowerMode().

 

This solution works, and thought that I am able to save current, but it is not constant, and sometimes for no specific reason the microprocessor is stuck in the Low_power mode, instead of the fact that the interupt on the GPIO is still send.

I tried to use the FLEXI_MODE but it don't save enough current at all.

 

Any idea let me know,

Best regards,

Florent
