Reset button remove power from Hibernation module? TM4C1294NCPDT

Edit: Scroll down, the updated code is in another later post.

hi,

Does the reset button or debugging remove power from the microcontroller?

I'm trying to debug a problem using the Hibernation module on the Connected Launchpad. I'm working on a RTC program that displays date and time on a Nokia5110 LCD. I'm using the button 1 & 2 on the launchpad to interact with the setup mode. I have a function that sets the time and one that displays it. I'm using all local variables in functions.

Everything works good after, I set the time in setup. But reset on the board or flashing screws it all up again.

It's like the Hibernation module is losing power or I'm programming it wrong.

I have some cleaning up to do. but here is the code:

#include <stdint.h>
#include <stdbool.h>
#include <string.h>
#include <time.h>
#include "inc/hw_gpio.h"
#include "inc/hw_hibernate.h"

#include "inc/hw_memmap.h"
#include "inc/hw_sysctl.h"
#include "inc/hw_types.h"
#include "driverlib/debug.h"
#include "driverlib/gpio.h"
#include "driverlib/hibernate.h"

I can post the Nokia5110 files If anyone wants. But I think there is any bugs in them. I use them all the time in other programs with no problems.

Thanks for any help;

Hi,

The reset button does not remove the power from the micro - instead, your software is the cause of all problems:

You do not mention if you have or not a backup battery for your hibernation module - so if you remove the power your data is lost. Also, all resets clean up the RAM memory and while you have local variables (which is neither a quality or a bad thing) a time structure with 0 content is called to set up the calendar, one line before while(1), eventually erasing everything before reading. So your program needs more tweaking - think about what is needed to do if the battery is present, hibernation is working and you weak up the micro.

One more thing - what about debouncing the switches? don't you need such thing? can this be avoided?

By the way, if you are using a launchpad the VBAT is connected to the VCC, it's not available at all.

hi thanks for the reply,

1. No battery, it's just the basic launchpad. But I looked at the schematic and it looks easy to add one.

2. I thought there where special registers that didn't get erased in the hibernation module on reset. If, it's using RAM. It makes sense that it would be erased. But wouldn't it get erased after leaving the setup function any ways? It is just a local variable. HibernateCalendarSet() must be saving the data somewhere else? It's just not in a safe place from a reset.

3. I was meaning to erase struct tm sTime; in main() but forgot. I'll get rid of it.

4. I know about the debounce on the switches. the way I have it now works pretty good. with the delay and action after the button released. timing doesn't matter in the setup anyway. It's just quick and dirty now. I ll likely change it before calling this done,

thanks,

dan

Hi,

Depending on your request - you should manage to display first and if the user decide it is wrong and need to be changed, then make changes and then save.

Take care how you manage the calendar - what the user need to enter for the year - as you have done now could be correct if the user is informed to enter only "14" instead "2014" - otherwise the calendar function may behave wrong.

As a test program could be OK, but for user point of view needs more tweaking.

I just soldered a terminal pin onto TP11 and removed the 0 ohm resister R39. I put a jumper wire from 3.3 volt to TP11. So, VBAT never loses power. then, removed power from the MCU by removing the jumper. The time still gets screwed up after reapplying power to the MCU. I need to figure out how the store the varaibles in the hibernation module backed up registers. but why wouldn't HibernateCalendarSet() that anyways?

I got it figured out. The struct being sent to HibernateCalendarSet() just needed to be a global variable. Just because I would have saved a lot of time had I seen this first before trying to figure it out. Here is the most updated code:

}

I done with this code for now and moving on to another part of this project. It's good enough for me. 


thanks,

I'll link the .c and .h files for the Nokia5110. if anyone wants to see them. They're adapted to work with Tivaware and writen by a professor of an online class I took last year.
