Do I need a programmer to start tinkering with this code on my mega 2650 or does it hook up straight to the PC via usb? I'm just starting out and am a noob here.

If you guys are revisiting code again and you get a chance it would be the best of both worlds if 2021 code was compatible with the geeteoh sound replacement board.

If anyone got the 2021 code to work with the geeteoh board please let me know. Maybe I'm doing something wrong.

I pulled my roygbev arduino out because they aren't compatible at this time. Having to choose I went with the geeotah board. The way to test compatibility is to just use the geeotah board and set the bank to numbers. Then you can trace the proper sound calls by pressing switches etc. Next plug in the arduino with the 2021 code and do some switch testing and you will notice there is communication between the two but it's way off.

Since there is communication I bet this is fixable and both boards may work together one day.

Well, I was going to try and tweak high/low nibble timings this evening and when the 2021 adapter was plugged in I couldn't even credit a game.

Last time I used the adapter it worked. It's plugged in correctly and I hear boot sounds. Just can't start a game. I remove the adapter and everything works. Tried using the extra ground wire and without.

Last time it worked I was on all alltek boards except the the aux driver board. The only thing that's different is now I have an alltek aux driver board as well.

Do these things suddenly go bad? Wish I had a known working one.

Any advice?

It's the roygbev turnkey solution. I didn't load it but I'm sure he used the same files as all of you. It has the usb port on the mega. Maybe I can just upload all the scripts again to rule out some kind of corruption?

Thanks for the support. I'm back up and running.

Can you experienced 2021ers tell me if it's safe to compile and upload from my laptop to the arduino adapter plugged into the mpu? If yes, and I don't have to remove it can I do it with machine power on or do I need to kill power to the machine?

Thanks for the tips. I'm up and running and tinkering. So has anyone done some neat stuff or expanded on any of Bluebomber's hard work?

Having spent a long time tracing the extensive code written by Tim and Dick I really need to mention how appreciative I am for all the hard work and love they put into this project.

By the way I'm ready to start tinkering with GPIO communication between the Arduino and a pi. Hoping to trigger video clips on the pi. Has anyone tried such a thing in this ecosystem? I know there is groundwork on the pi for programming triggerable video clips out there in a google search. Just haven't tried anything yet.

Here is an idea I pulled off trying to make the woodbeast target more fun. Challenge the woodbeast on the last target. It's a 50% random chance that you will either get the ball save and be man or the beast bites you. Meaning no flippers and a drain. I'll probably make the reward greater with a ball save and bumping the max balls up to 4.

An example of losing to the beast.

Thanks for the tips. I just got past my first hurdle. Don't fry the pi as arduino GPIO is 5v and pi is 3.3v. So I'm bench testing nowhere near flash gordon or your adapter.

This is the level shifter I'm using to keep the pi safe. Can't believe the dirt merchants selling a $35 pi at awelful mark ups.

Next I'll try and get communication going.
