Few Linux commands used to program AT Tiny 45
See if a program is installed (in this case a avrdude)
Command: fab@fab-desktop:~$ which avrdude Answer: /usr/bin/avrdude
Install a program
Command:fab@fab-desktop:~$ sudo apt get install gvrasm Command:[sudo] password for fab: //Insert Fab Password
Run the program
Command:fab@fab-desktop:~$ gavrasm
Change Directory
Command:fab@fab-desktop:~$ cd Desktop
List Files
Command:fab@fab-desktop:~/Desktop$ ls
Run the gavrasm to transform asm file to a ".hex" file (hexadecimal)
Command:fab@fab-desktop:~/Desktop$ gavrasm hello.RGB.45.MTA.asm
Run the Avrdude comunicate to t45 using the parallel port
Command:fab@fab-desktop:~/Desktop$ avrdude -p t45 -c bsd -U flash:w:hello.RGB.45.MTA.hex
Answer:avrdude: can't open device "/dev/parport0": Permission denied
Answer:avrdude: failed to open parallel port "/dev/parport0"
List [ls] paralel port with detail [-l] (crw-rw----)
Command:fab@fab-desktop:~/Desktop$ ls -l /dev/parport0
Answer:crw-rw---- 1 root lp 99, 0 2010-01-14 11:30 /dev/parport0
Change permission to access parallel port, and insert fab user password
Command:fab@fab-desktop:~/Desktop$ sudo chmod 0766 /dev/parport0
Command:[sudo] password for fab:
List [ls] paralel port with detail [-l] and check the permission differences (crwxrw-rw-)
Command: fab@fab-desktop:~/Desktop$ ls -l /dev/parport0 Answer:crwxrw-rw- 1 root lp 99, 0 2010-01-14 11:30 /dev/parport0
Run the Avrdude comunicate to t45 using the serial (com) port and install the hexadecimal program "hello.RGB.45.hex"
Command:fab@fab-desktop:~$ avrdude -p t45 -c dasa -P /dev/ttyS0 -U flash:w:hello.RGB.45.hex
Answer:== Run the Avrdude comunicate to t45 using the serial (com) port and install the hexadecimal program "hello.RGB.45.hex" Answer:if you Answer:are not in the directory where the file is. In this example is w:/home/fab/Desktop/hello.RGB.45.hex ==
Command:fab@fab-desktop:~$ avrdude -p t45 -c dasa -P /dev/ttyS0 -U flash:w:/home/fab/Desktop/hello.RGB.45.hex
