Stack-pointer positionirung

ich habe diesen fehler bekommen:
main.S:169: Error: number must be less than 64

Code:

---

        ldi                r16, RAMEND
                out                SPL, r16                ; setup stack pointer

---

der kontroller hat 128 byte sram also warum dann "less 64"

Hat er auch.
Mit *etwas* mehr Info könnte man dein Problem evtl nachvollziehen.
Niemand hier kann so sehen, wie groß das ominöse RAMEND wirklich ist, wo es herkommt (wahrscheinlich ausm Linkerscript), wie dein Maklefile aussieht, die inkludierten Dateien aussehen, etc.

main.S=???

#
# On command line:
#
# make all = Make software.
#
# make clean = Clean out built project files.
#
# make coff = Convert ELF to AVR COFF (for use with AVR Studio 3.x or VMLAB).
#
# make extcoff = Convert ELF to AVR Extended COFF (for use with AVR Studio
#                4.07 or greater).
#
# make program = Download the hex file to the device, using avrdude.  Please
#                customize the avrdude settings below first!

# make filename.s = Just compile filename.c into the assembler code only
#

# will not be considered source files but generated files (assembler
# output from the compiler), and will be deleted upon "make clean"!

Das geht so nicht.

Du musst wirklich die Dateien posten, nicht als [code].
Im Makefile stehen zB TABs, die müssen auch da stehen bleiben, aber das liefert der BBcode nicht.

Ich geh erst mal ne Runde flitzen. Ich schau morgen noch mal drauf.

Hallo,
ich gehe davon aus, daß es sich um die Code von "Fehler in Assembler-Code" handelt.

Dort war ja noch die Zeile
.include <2313def.inc>

vorhanden,
jetzt ist sie nicht mehr da.....

Zitat:

---

Niemand hier kann so sehen, wie groß das ominöse RAMEND wirklich ist, wo es herkommt

---

laut 2313def.inc

Zitat:

---

.equ RAMEND =$DF

---

Gruß Sebastian

#define RAMEND 0xDF
das steht in der io2313.h(das kann man daran sehen das io.h inkludiert ist ich dachte das wäre klar da es sonnst nirgends ist und jeder io2312.h haben wird).

Mit deiner vermutung ligst du richtig alerdings habe ich das erst mit andrem programm versucht und musste das anpasssen. Hier ist das original.

Hmmmm, es ist doof, daß es am Stackpointer schon scheitert.
Leider habe ich es noch nicht versucht Assembler und C zu mischen, aber warum includest Du das nicht, so wie es auch im assembler gemacht wird.

am anfang von main.S
.include"2313def.inc"
und io.h weglassen,
wenn der immer noch kotzt, die Datei 2313def.inc mit in das Verzeichnis.
Ich würde es so probieren......

gruß Sebastian

die 2312def.inc habe ich von avr studio da win-avr keine hat

O weh,
Dann war das doch keine all zu gute Idee,
es war aber ein Versuch wert.
Da stand aber im Kopf der Datei ingandwas mit compiler Flag,
bist Du denn daraus schlau geworden?

Zitat:

---

; Code is written for use with AVR-GCC in assembler mode
; flag: -x assembler-with-cpp

---

Versuchs mal mit dem Code unten.

Falls das Programm nicht implizit davon ausgeht, daß die Datenfelder sine, triangle, etc auf 256-Byte-Grenze aligned sind, kannst du dir den durch das Alignment verschwendeten Platz sparen.
Wirf dann einfach die ".align 8" Zeilen raus.

Code:
