    Atmega328 PONG

    I'm trying to build this Atmega emulated pong circuit:

    http://searle.hostei.com/grant/AVRPong/index.html

    Not having much luck getting it going, getting something on screen but mostly a jumbled mess of lines.

    I'm programming directly from the breadboard via a USB AVP programmer, using XtremeBurner software.

    I believe my issue is that I'm not setting the low fuse bits to set an external clock. I've tried but just end up bricking the Atmega328P chip.

    Anyone familiar with how to enable an external 16MHz crystal when flashing the Atmega328P?

    Got it working. Pretty cool little pong project.

    Low fuse for 16MHz crystal is 0XFF

    Had to omit the 1000R from the sync line for stable image.IMG20190210221430.jpg

    I'm going to design a PCB for it, it's a really nifty little project.

    I plan on 3D printing some enclosures for the paddles and making them external to the PCB, they'll connect via a cable with JST plugs.

    Rather cool that you can do this with so few components. The Atmega emulates the pong chip quite faithfully. The Arduino TV out interface is great, there's other games you can do like space invaders etc.

    PCBs arrived, really happy with how it turned out.

    I've designed it to use parts that are all available from Jaycar and printed the part numbers on the back of the PCB.

    I can sell the PCBs, then let people supply and solder parts themselves. Jaycar and Altronics etc have all the parts available.

    Finished this project off. Made some improvements to the PCB.

    I'll be listing a small handful of PCBs in the for sale section soon. I can supply a pre-programmed Atmega328 if needed. Remainder of parts can easily be sourced from Jaycar, part numbers printed on the reverse side of the board.

    Awesome mate, you and Kaizen would have plenty to talk about for sure.
