Help : Firmware into Usbasp ( AVR Programmer) !!

[raman00084]

You have to use an AVR programmer to build the USB programmer.

You can find many programmers in the Internet, a simple one is this
AVR Programmer

Alex

it necessary to set the fuse bits for the above programmer are it will set by itself ( ponyprog serial icsp programmer)

 

[alexan_e]

The fuses are set individually from the flash program , you have to select the appropriate fuse settings in the ponyprog dialog and write them

 

[raman00084]

how to set the fuse settings in ponyprog, it depends on what the crystal used are any other.

If you open the readme file included in USBasp archive ( https://www.fischl.de/usbasp/ ) you will find

Firmware:
Flash "bin/firmware/usbasp.atmega88.xxxx-xx-xx.hex" or
"bin/firmware/usbasp.atmega8.xxxx-xx-xx.hex" to the used controller with a
working programmer (e.g. with avrdude, uisp, ...). Set jumper J2 to activate
USBasp firmware update function.
You have to change the fuse bits for external crystal (see "make fuses").
# TARGET=atmega8 HFUSE=0xc9 LFUSE=0xef
# TARGET=atmega48 HFUSE=0xdd LFUSE=0xff
# TARGET=atmega88 HFUSE=0xdd LFUSE=0xff

You can either enter these values to ponyprog or convert them to individual fuse setting using a calculator like https://www.engbedded.com/fusecalc
