💬 Various bootloader files based on Optiboot 6.2

[DavidZH]

I have tried with your bootloader on 16MHz and 8 MHz with crystal.

8MHz, crystal, 1V8

Warning: Board breadboard:avr:atmega328bb doesn't define a 'build.board' preference. Auto-set to: AVR_ATMEGA328BB
Build options changed, rebuilding all

Sketch uses 16,680 bytes (51%) of program storage space. Maximum is 32,256 bytes.
Global variables use 942 bytes (45%) of dynamic memory, leaving 1,106 bytes for local variables. Maximum is 2,048 bytes.

16MHz, crystal, 1V8

Sketch uses 16,694 bytes (51%) of program storage space. Maximum is 32,256 bytes.
Global variables use 942 bytes (45%) of dynamic memory, leaving 1,106 bytes for local variables. Maximum is 2,048 bytes. 

So the 16Mhz file is actally even a bit bigger. I also tried if changing the BOD voltage would change anything, but nope on that.

Might be something to look into in a spare hour.

hy,
can anyone tell me what is the word near cpu 8mhz-38k4-d13 etc..??

[Samuel235]

@mar.conte - Your question isn't very clear. If you're asking what the name means its broken down as:

8mhz - Crystal speed/frequency
38k4 - 38400 upload speed
D13 - Pin 13 to flash the LED (if needed) just for visual indication that the bootloader has been burnt/installed.

Not sure if that is what you meant but I could only assume. If not then please attempt to explain a little clearly for us :)

Hope that sorts your problem!

[mar.conte]

@Samuel235
Sorry for my english, your answer is ok Tanks you

[Samuel235]

@mar.conte - Its okay, i understood you, just about ;)

Now just apply that description to all of the other bootloader varients that the great @Gertsanders has provided us with :)

[mar.conte]

Help!!!
I have upload bootloader 8mhz 38k bod 2,7 and internal clock with sketch j gammon!!!
Consumption 2 mh!!!
Why?
Tanks

[Samuel235]

I'm sorry, i don't understand the issue at hand.... Could you attempt to explain any clearer?

@Samuel235
Hy
My project is simple atmega328 with internal clock 8 mhz in powerdown mode end rfm69 hw which send to gateway when pir motion is high powered all with 2 aa battery.
The First test what i do is in breadboard atmega328 with optiboot 6.2 ( i have upload bootloader 8mhz internal , 38vk, bod 2v7) and simple sketch j gammon: result no microampere but around 2/5 mah in sleep mode;

[alexsh1]

@mar.conte I'm not familiar with the sketch you mentioned. The best is to use the voltmeter and oscillograph to determine consumption.

Why do you have BOD 2.7v? I do not have any BOD - this would let a node to run on two batteries until voltage drops to below 1.9V

[mar.conte]

@alexsh1
I have only voltmeter extec, can i mesure ua?
Can you send simple sketch for deep sleep ?

[Samuel235]

@mar.conte - Are you basically saying that your hardware is using too much power to enable you to run on battery for any substantial time?

[mar.conte]

@Samuel235
Yes, i want obtain few micro amp but its two month wich i try without result.....

[tonnerre33]

@mar.conte Which skecth did you use ?
Did you have radio errors in your log ?

[Samuel235]

Could you please either include your sketch here or give us a link to the example sketch that you used please.

[mar.conte]

@Samuel235
Resolved
I have try with sketc j gammon https://www.gammon.com.au/forum/?id=11497
And the problem are pir input (model hrc-501)
Are ever high and the cpu dont go in sleep.
I have remove pir and all ok the atmega run 20 uah very good.
Can you advise a good pir wich run to 3,3 V for my project?
Tanks

[mar.conte]

@mar.conte
im not sure why pir with simple test like this http://playground.arduino.cc/Code/PIRsense is ok
but with my sketch the cpu reset forever

Firstly, i can't read the structure the way you have posted your sketch. You should use the code function in the reply, the icon looks like "</>" above where you make your reply. Put your code in there for us to have any chance of reading it at all.

Secondly, I don't think that this is the place to be posting this issue. For a start, this isn't an issue relevant to the bootloader in this thread and secondly, it doesn't even have anything to do with MySensors.

[alexsh1]

@mar.conte yes, you can measure consumption (should be in uA) while sleeping with a good voltmeter.

However, I really fail to understand what has Nick's sketch you mentioned to do with MySensors? I suppose some people here may be aware of sleeping issues, but again your problem has nothing to do with MySensors.

Please see the following - it may help you troubleshoot your issue

@Samuel235
I wanted to build my projects with mysensors, first of all I started with bootloader found in this section to try them with examples that I know because I do not know yet mysensors, I wanted to learn it so I took the liberty to insert code in your section. if you can figure out my problem thank you or I apologize for the trouble thanks
