Programming the FABISP
Download and unzip the firmware.zip files and the development tools for AVR micro-controllers. Software required for windows: Editing the “make file” using TextEdit:
DEVICE = attiny44 F_CPU = 12000000 # edit this line for crystal speed, in Hz #F_CPU = 20000000 # edit this line for crystal speed, in Hz FUSE_L = 0xFF FUSE_H = 0xDF AVRDUDE = avrdude -c avrisp mkii -p usb -p $ t44 # edit this line for your programmer Save the file.
Open the command window and navigate to the directory where the firmware files were saved. In the command window type:
make hex ....... building main.hex make program ... flashing fuses and firmware make fuse ...... flashing the fuses make flash ..... flashing the firmware make clean ..... deleting objects and hex file
Well configuring the make file and editing it was never easy and I didn't know who to consult as I didn't have internet but thanks to Mercedes Mane work making it easier for me to understand. |
