Hi all,

working with unsigned vars, calculating the absolute value of the difference between to vars afforts a couple of steps.

Example using byte-constants:

89-5 = 84 'OK

5-89 = 171 'not ...

OK. Got it.

In difference to "sjgfjhasgfuzawgu" (will not be compiled), "ON PCINT18 my_ISR" will compile. That lead my to assume that this is a valid Interrupt. That lead me to use PCINT1, expectin ...

MWS, I got it.
PCMSK0 relates to Pinb.on PCINT18 isr18

meant for?

Hello,
I'm working on pin-change-interrupt to get SW-Uart to work. I'm encountering problems, so I stripped down the thing to the essenrtial.
As you can seen, I achive to trigger PCINT on pulsed out ...

It seems to me, we are running into an dead end here.
Actually it is only about a watchdog, it is not THAT tricky, I think.
I always use the WD, and I never needed to worry about ASM-code and stuff. ...

Option 43:

Think of letting the Date/Time thing down. What meaning does it have, in case the item stays in the shelf for 7 month.
Rather use serial numbers. Note whatever information which is usef ...

From the HELP (Fundamentals):

Double: 8 Bytes; 5.0 x 10^–324 to 1.7 x 10^308; Doubles are stored as signed 64 bit binary numbers

in short words: assigning FFF... all over a double does not re ...

My last attempt: g

show us at least a snippet of code that shows how you measure V11 and V12, and how getting V12 affects the content of V11. Rolling Eyes

Ok, we are shifting from SW to HW.
If V11 equals V12, and that is not what you expect, you need to find out what is going wrong.
HW could have an error.
SW could have errors.
Your expectations ...

yes I agree with MEISTER, extra vars for the Results are needed, and shure even some more.
Be generous with vars, there are a lot of then avaliable in most chips...

I guess the TO cannot see the w ...

Hmmmm....
If you need to handle 8 cells having 2 values (load on/off), I'd expect 16 variables!
Vcell1_off
Vcell1_on
Vcell2_off

Vcell8_on

to keep it simple in the first attempt, I'd n ...

V2 and V1 cant be differentiated as both are reading the same adc and cell.
But you GET V1 without load, then switch on the load, then GET V2, right?

Now threr are 8 cells; I STILL don't get what ...

I almost do not dare to ask you:
Do you know how to use variables?
Dim V1 as word
Dim V2 as word

I still don't get what you are trying to do.
Afaiu you get the bat voltage, then put a load on the bat and measure again.
This way you find the inner resistance, right?
Then you repeat this to fi ...

I've used the intellihead shift-out reading-head by magtek with success. If you are interested, let me know!
