Code Blocks

[petterp]

Hur gör man för att skapa en HEX fil i codeblocks när man skrivit ett program för AVR?


tack på förhand

Nu har jag ingen vidare koll på varken Codeblocks eller AVR-programmering, men det låter som om du vill kompilera din kod, och detta görs ju med en kompilator. Så om du inte konfigurerat Codeblocks till att använda din AVR-kompilator, så får du helt enkelt göra det för hand via terminalen

[petterp]

Den använder AVR-GCC kompilatorn, jag kompilerar filen men problemet är att jag inte får inte ut någon HEX fil.

Har du testat avrdude ?

[petterp]

Med AVRDUDE kan jag väll bara skicka Hex filen til avr'en som jag inte får ut av code blocks.

När jag skriver program till min AVR Butterfly använder jag Emacs att skriva C-koden i. Därefter väljer jag helt sonika Compile i menyerna. Då jag har stulit en makefil från de exempelprogram som finns på smileymicros (http://www.smileymicros.com/) och har AVR-GCC installerat så löser Emacs det bra. Så förutsatt att du har en bra makefil och AVR-GCC installerat så rekomenderar jag Emacs.

När jag sedan ska skicka över så använder jag avrDude som nämndes ovan. Dock orkar jag inte skriva in hela den långa raden varje gång så jag skapade ett Nautilus-script så jag bara kan högerklicka på .hex-filen och välja "Send to butterfly"!

Vilket hexformat förväntar sig programmeraren? Om det är intelhex, vilket verkar vara nån slags standard, kan du prova objcopy.

T ex:

/usr/bin/avr-objcopy -R .eeprom -O ihex <filnamn>

Vad är det för AVR du programmerar till?

Här kommer i alla fall en exempel-makefil. Den kommer med när man installerar WinAVR och jag använder den framgångsrikt till min Atmega169. Lättaste sättet att kompilera är från valfritt terminalfönster. Bara att gå till mappen och skriva "make".

raden:

Kod: Markera allt

FORMAT = ihex

talar om för AVR-GCC att det skall skapas en .hex-fil.

Kod: Markera allt

MCU = atmega169

Talar om att det är en atmega169. Ändra till den mikroprocessorn du använder.

Kod: Markera allt

TARGET = file_without_ending

Vilken fil ditt program finns i. Också det namn som .hex-filen får. Utelämna dock ".c" när du skriver in filen.
