why does not the "aa" value increase in the tiny10 circuit?

[Sampsa Lahtinen]

#chip tiny10, 1

dim aa as Byte

dir portb.0 out



do

aa=aa+1

 if aa > 100 then
    portb.0=1
    end
 end if

Loop

There is a superfluous "end" that should be deleted.

Also, use the "else" condition to turn off the portb.0, if the excersise is to blink an led? For code tags tap the code</> in the menu and paste code to preserve formatting.:

do
  If aa > 100
    portb.0 = 1
  else
    portb.0 = 0
  end if
  wait 1 ms
loop

need some aa = aa +1 action in that do loop...

@Sampsa - welcome

MotoGeek and Kent are spot on you logic is not going to do very much but they give great advice.

[Sampsa Lahtinen]

Oukei.
The problem seems to be compiler (ver.0.98.02) with attiny10 ic. The compiler uses r0 for the variable aa in the example. I think it should go to r16 place? Could developers check this?

Post the source code please. It may be the same as the initial posting in 2017 but it may not be, please post.

chip tiny10, 1

dim a1 as Byte

dir portb.0 out

do

a1=a1+1

if a1>3 Then
' portb.0=1
goto loppu
end if

portb.0 = 1
wait 500 ms
portb.0 = 0
wait 500 ms

Loop

loppu:
End

i test asm with AVR studio5 and compiler say "invalid register .DEF SYSTEMP1=r0"
LED flashes but does not stop after three steps?

Error 5 Invalid register C:\Users\Sampsa paja\Documents\AVRStudio 5.1\AVRAssembler1\AVRAssembler1\AVRAssembler1.asm 36 0 AVRAssembler1

Known issue with core = AVR8L_0 devices (i.e. ATtiny4, 5, 9, 10, 20, 40, 102, 104).

I have dropped the ball on providing Anobium with clean .dat files for this AVRseries. I believe I have a tool driven .dat generator (April 2018) for the ATtiny10, and separately have parsed the maxmhz and pins for Sot23 device. They have not yet been merged to a single tool, single .dat generator, need to do that :-)
