USBasp wiring is incorrect #2

Open BoxOfSnoo opened 10 years ago

BoxOfSnoo commented 10 years ago

The wiring on this page is incorrect. The ground wire should go to pins "1,3,5 or 7" instead of "pin 8". "Pin 8" is not connected to anything in the programmer. Once the ground wire is connected, the Freematics device is powered and programmable.

Additionally, the pin numbering in that page looks to be incorrect.

See the USPasp page for reference.
