3. Programming

To program the FabISP, you first need to install the necessary software for your operating system and download the firmware. Edit the Makefile. Set the fuses / program the board. Verify that the board is working properly. Desolder jumpers to turn it into a programer.

This are the steps (for Mac): First step is install the Crosspack AVR. Get Xcode (If you don't have it).  Get Make (via Xcode). Get FabISP Firmware (MacOS 10.8.2 - current). Connect the AVR to the computer and the FABISP to the AVR (In this step you will know if you have done your board correctly). Then go to the folder where you put the FabISP Firmware and run this make clean. Next type this make hex. And then this make fuse (so your board can use the external clock). Then we program to finally make it a ISP with this make program.

If you have done everything correctly, you will receive a success message.

And the last step is to check if your computer identifies the FabISP. For doing this go to About this Mac > System Report > Hardware > USB, there you should see FabISP listed.
