Editing Converting NerD60 to TMK (section)

===Test the connection to the keyboard===
* The keyboard must be unplugged
* On the USBasp set the jumpers for '''Power''' and '''Slow''' (if you don't set it to '''Slow''' the ISP will be too fast and you get "miss-fires" while reading or writing, at least this was my case with USBasp)
* Connect the breadboard cables to the ISP headers on the PCB. 
* On the '''v1.6''' PCB this ISP headers are located on the bottom of the PCB where the Spacebar resides (right under the '''''NerD''''' logo). This is how they look:

* On the '''v2.1''' PCB the ISP headers are next to the ''Caps Lock'' switch, on the left side of the PCB.
* Plug the USBasp in your computer (the green Power LED should light up on the programmer)
* Now it's time to see if you ca read data from the controller (do it for more times to make sure it works every time, if you get warnings don't ignore them and don't use '''-F''' as in ''force'' !!):
