<Hello AVR-ATMEL Family,
Currently we are implementing project using Sleep mode by using AVR128DA48 controller, But it is not Entering the Sleep Mode and mention the steps if possible.
How we can Debug the process if it Entering the Sleep mode
Eagerly waiting for the Reply...
Thanks in Advance...>
Welcome to AVRFreaks
But it is not Entering the Sleep Mode
how do you determine that? What symptoms are you seeing, and how are you observing them? What were you expecting?
Have you checked the Product Page for Application Notes, example code, etc?
How we can Debug the process if it Entering the Sleep mode
A conventional debugger seldom works well - when a CPU is asleep, it often can't do "debug stuff".
I would suggest that you make a minimal demo project that just goes to sleep, and wakes up; eg, on a timer - then watch current consumption to see if it is, indeed, going to sleep...
for verification Im checking LED ON/OFF , With this way Im checking.. But LED is always ON
So do you have a debugger to step through the code, to see what's happening up to the point where it should enter sleep?
Post a minimum but complete program which demonstrates the issue; also your schematic.
See Tip #1 in my signature, below, for how to post source code & images:
PORTA_OUT &= ~PIN4_bm;
while (1)
{
touch_process();
sleep_mode();
SLPCTRL_init();
SLPCTRL_set_sleep_mode(SLEEP_MODE_STANDBY);
PORTA_OUT |= PIN4_bm;
_delay_ms(1000);
}
Note : It is working fine whenever there is an Absense of PTC Touch and It is not working as per when it is having
PTC Touch uses interrupts so the CPU will wake up at that time.
Hello KABASAN(JAPAN),
Hope you are Safe and Healthy
In Realtime we have to Implement the Sleep MODE whenever it is having PTC
Can you help me to Resolve this Issue, So that Our PTC Touch does not affect our implementation
for reference,
Code :
PORTE_OUT &= ~PIN3_bm;
while (1)
{
touch_process();
sleep_mode();
SLPCTRL_init();
SLPCTRL_set_sleep_mode(SLEEP_MODE_STANDBY);
PORTE_OUT |= PIN3_bm;
_delay_ms(1000);
}
Controller : AVR128DA48
Software : ATMEL 7.0
Note : Even we are not Touching any Touch Button to Enable th interrupt , then how the Interrupt is Generating ?
Thanks and Regards,
Ramesh Janagi
The ADC is always running to determine if the button is touched or not.
If the current consumption is unacceptable, you have no choice but to disable touch.
Therefore, many devices use mechanical switches only for the power button.
You didn't read the instructions on how to post source code, then?
Even we are not Touching any Touch Button to Enable th interrupt , then how the Interrupt is Generating ?
It has to be constantly measuring the capacitance to be able to detect a change - which is what indicates a touch.
This is why many systems have a physical button to wake up, and then only use touch when awake ...
You're going to have to dig into the PTC documentation for any tips on optimising its power performance.
As we Discussed with Our client we have to make sure that, Touch PTC Sensor should be Included
So in Real Time PTC Touch should be there, So can anyone tell How we can Resolve this Issue whenever the Module is Having PTC Touch with it..
Thanks in Advance
To have touch working, you need the CPU working - there is no way around that.
Again, have you looked at the PTC documentation to see how it can be optimised for low power?
In Real Time Im Using more than 12 Touch Buttons, As of Now Im using only Two Touch Buttons
One Touch Button will work as an Input (Interrupt) to my Controller and Another will be Configured as an Low Power Mode
I once used an Atmel touch sensor chip to wake up/power up the rest of the board, IIRC it was one of the 6 pin AVR's that was preprogrammed for this function....

Hello
AVR Atmel Support Team,
I have few Questions, can anyone answer for these Questions below mentioned :
1. What Happens If AVR Controller Entered into Sleep Mode
2. In my Configurations Im Using PTC Touch, LED and UART 'Printf(" "); Statement for Debugging Purpose
3. IF LED's and UART Printf(" ") will works , Incase if controller enters Sleep mode ??
4. Or, LED's and Printf statement will works as usual in Sleep Deep mode..
Thanks in Advance

You haven't said what Sleep mode you're using ?

Im Trying with all Possibilities to Implement SleepMode() in AVR128DA48 Controller, facing so many Difficulties
Can anyone Help ?
Does Anyone knows How to measure Current Consumption method for AVR128DA48 Controller to Confirm that whether the controller in Sleep mode or not ?
Errr ... with a (micro)ammeter ?
For more than just "static" current, you will need something like this:
https://www.microchip.com/en-us/development-tool/ATPOWERDEBUGGER
Be sure that you are measuring only the micro - not also other parts of your circuit.
Nowadays, dev boards usually have a facility for measuring current; eg,
if you're on a custom board, you will need to make sure you provide means to do it.

As clawson said, you need to go to ST's forums for that: https://community.st.com/s/topic...

Oh - you already have: https://community.st.com/s/quest...

How to configure for Sleep_mode with PTC (low power consumption. (AVR128DA48)
Have you read any of the previous posts, and studied any of the mentioned documents - datasheet, application notes, etc ... ?
clawson I tried this earlier. If you either google "AVR128DA48" or follow my link in #18 it used to go to a specific product page for the DA devices and that then had a Document tab that made the application notes available. But now if I do either (the Google or just use link #18) it just goes to some generic marketing waffle. It's like the actual device pages have been removed - presumably something to do with non-availability of silicon ?
So it does.
But google can still find the documents:

When I click the link this is what I see...
Note the microchip.com URL has apparently redirected to aem-origin.microchip.com
I spend most of my life attached to a German VPN so as far as microchip.com is concerned it looks like I am accessing from Germany so perhaps this is just a geographic redirect. This seems odd - most Germans read/write English better than the majority of the English (IME!) why shouldn't they get access to English data and documents?
I'll break the VPN link and try again...
EDIT: yup that worked now - wonder why microchip are preventing German's finding out about AVR-DA processors ?? (I rather suspect this is NOT a deliberate act but just an IT dept FUBAR !)
EDIT2: Oh this is spooky - my IP doesn't just make me look German - it makes me look like I work for Continental in Germany and the page I reach is "Solutions for ADAS Applications" - Can it be that microchip are specifically targetting engineers from car development companies with stuff specifically about Advanced Driver Assistance Systems ? - quick, play the Twilight Zone music !!
also working for me (at the moment):
and now that, too, is now broken - redirecting to the https://aem-origin.microchip.com/ page
the page I reach is "Solutions for ADAS Applications"
For me, that's just a banner scrolling through several different things - including an ADAS one:
EDIT
It looks like all the Product Pages might now be broken - even https://www.microchip.com/en-us/product/ATmega328P

Probably due to the recent solar flare event! 
Looks like someone has well and truly borked the website.
clawson Ah probably just DNS propagation then? They probably have the same bloke controlling their DNS as Facebook use!
