Hi,
Trying to program an ATMEGA328P. I understand that this can be done with my GQ-4x4 by using an AVRISP. The problem is that my chips aren't in a device that can be programmed via ISP. What do I need to get to be able to program it? Everything I find is the programmer side, not the other side of the cable. Specific product names appreciated. |

Only power is required. |

Why does everything I see talk about clock sources and things like that? |

Your PCB already provide the clock signal, you only need to power it and connect the five wires from the GQ-4X to the chip. |

That's the thing, I don't have a PCB, as mentioned "The problem is that my chips aren't in a device that can be programmed via ISP. ". So I have only the GQ-4x4 and a chip. |

You need a PCB or a breadboard. |

The PCB that this goes into doesn't have any programming points. That's why I'm trying to find out what I need to buy/breadboard. Is there a schematic or item I can refer to? |
