| Description | Command | Answer |
|---|---|---|
| See if a program is installed (in this case a avrdude) | which avrdude |
/usr/bin/avrdude |
| Install a program | sudo apt get install gvrasm |
[sudo] password for fab: //Insert Fab Password |
| Run the program in this case gavrasm | gavrasm | |
| Change Directory | cd Desktop | |
| List Files | ls | |
| Run the gavrasm to transform asm file to a ".hex" file (hexadecimal) | gavrasm hello.RGB.45.MTA.asm | |
| Run the Avrdude comunicate to t45 using the parallel port | avrdude -p t45 -c bsd -U flash:w:hello.RGB.45.MTA.hex |
avrdude: can't open device "/dev/parport0": Permission denied failed to open parallel port "/dev/parport0" |
| List [ls] paralel port with detail [-l] (crw-rw----) | ls -l /dev/parport0 |
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 | sudo chmod 0766 /dev/parport0 |
[sudo] password for fab: |
| List [ls] paralel port with detail [-l] and check the permission differences (crwxrw-rw-) | ls -l /dev/parport0 |
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" | avrdude -p t45 -c dasa -P /dev/ttyS0 -U flash:w:hello.RGB.45.hex | |
| Run the Avrdude comunicate to t45 using the serial (com) port and install the hexadecimal program "hello.RGB.45.hex" if your are in the directory w:/home/fab/Desktop/hello.RGB.45.hex | avrdude -p t45 -c dasa -P /dev/ttyS0 -U flash:w:/home/fab/Desktop/hello.RGB.45.hex |
