*Setup tools in Linux Debian box

**login to root user

**install avr development tools, using the command "<code>apt-get install binutils-avr gcc-avr avr-libc uisp"</code>

*[http://www.linuxfocus.org/English/November2004/article352.shtml#352lfindex8 prepare a simple avr serial programmer]

**examples to use the above programmer with uisp (assume in ATmega8535, by above simple serial programmer, printer port, debian linux box, hex file as avrm8ledtest.hex)

*** Read the Fuse : <code>uisp -dprog=dapa --rd_fuses -dpart=ATmega8535</code>

Read the Fuse*** Erase Whole Chip : <code>uisp -dprogdlpt=dapa/dev/parport0 --rd_fuseserase -dprog=dapa -dpart=ATmega8535</code>

Erase*** WholeProgram Chip : <code>uisp -dlpt=/dev/parport0 --eraseupload if=avrm8ledtest.hex -dprog=dapa -v=3 --hash=32 -dpart=ATmega8535</code>

Program Chip : uisp -dlpt=/dev/parport0 --upload if=avrm8ledtest.hex -dprog=dapa -v=3 --hash=32 -dpart=ATmega8535

</nowiki></pre>

* if you buy a new chip, you cannot program this chip by the above serial programmer. You must have a avr parallel programmer to set the Fuse High Byte - SPIEN bit to logic LOW. Please take a look of [http://www.atmel.com/dyn/resources/prod_documents/doc2502.pdf page 236 of atmel datasheet 8535 as example]. Then
