How can I to hibernate tiva C using energia IDE?

Other Parts Discussed in Thread: ENERGIA, EK-TM4C123GXL

Good morning.

I have a DS3231 and I want to hibernate Tiva C (TM4C123GXL) and wake up It with the rtc alarm.

I did the alarm configuration, but, I couldn't configurate the hibernation module using Energia IDE.

The microcontroller will has some sensors and sd card. So, It has a cycle:

 

     wake up (with rtc alarm) > read the sensors > write the data > (send in some hour of day) > hibernate

          ^-------------------------------------------------------------------------------------------------------------------------°

  

I want do this to microcontroller keep a low power consumption and don't need stay processing all time, just in some moments for

read data and write in sd card. 

I read the TivaWare documentation and the tiva c 123gxl datasheet, anyway, I couldn't set hibernation on Energia IDE and

set pin configuration too, because I want to use the RTC 32KHz clock in this case.

 

Has anyone done this?

 Thanks for help me.

    Hello Luy,

    On Energia, I haven't done so, but a few careabouts that you must know. The EK-TM4C123GXL does not support VDD3OFF mode, so you would need to configure it in VDD3ON Mode. What you need to check is if the HIBn signal goes from High to Low.
