Architecture history / Combined data and program address space
I will not put any code here, but I'm a bit surprised you never have used it!   With the GCC there is really a lot of speed (and code size) to be gained if you put some...

Architecture history / Combined data and program address space
The first dev. for AVR's was only for 1200 (2313) and 8515 (4414 )(and some Atmel 8051 chips). And that was sometime in 1997. (I got it with a ES 1200)  There is a 1996...

sbi & cbi
And I will comment :  It is well known for driving AVR assembler programmers crazy because it functions similarly to the CBR instruction Nonsense the CBR is one of those...

To #20 and : im looking for a solution for chip that contains internal averaging or whatever solution to dynamic weghing What you need is to estimate the flow, and from there you...

Architecture history / Combined data and program address space
First when the new  avr0/1 came out I checked the compiler (current GCC) if it actually used the flash to data mapping, and at least the first versions didn't it still...

? So memcpy() in C don't matter ? Using pointers in C don't matter ?   I give up

LOADCELL ADC
 it takes around 1-2 second to get a steady reading Why do you think it would be any faster with a external ADC ?

Read the thread :)   on a ATMEGA48 you can point to r14 with X Y Z and use LD and ST instructions, that you can't do on a 4809.

Between the 8414 (never released) and 8515 there was made instruction changes suggested by IAR, to help the C compiler.

How many watts of solar would I need?
If we say 3 KWH a day, with sunshine about 5 hours (and cloudy and other 3-5 hours) , will need about 500 W so 2*250W panels, but better with about 3 panels. if you live a very...

This is from the mega328 datasheet. The left addr. is for IN and OUT, the other is for LD and ST, and that is the way all the old AVR's with RAM handled it.
