Awesome! Thank you for your help and such a detailed explanation! I haven't set up or used the IR battle system yet, so I wasn't sure how it works.LukeZ wrote: ↑Sun Aug 31, 2025 8:08 pm You don't need to assign anything to the repair sound, you only need to load the repair sound into TBS Flash and make sure whatever sound number it is, shows up in the 2d coder column as shown in the Wiki. The TCB will tell the Mini to play the repair sound, whenever it detects that you have received a repair IR signal. So it is not you that trigger the repair sound from your transmitter, it is the fact that the TCB has detected a repair IR signal. Likewise the cannon hit sound will be played automatically when you are "hit" with an IR battle signal - this is not something you control from your transmitter, nor do you need to assign any functions to it in OP Config.
Basically, don't concern yourself with trying to trigger the sounds on the Mini. Load the sounds into the Mini, yes; arrange them in TBS Flash as shown in the Wiki, yes. But let the TCB take care of telling the Mini when to play them. If your battle opponent shoots you with his IR transmitter, the TCB will tell the Mini to play the cannon hit sound. If someone sends you the repair IR signal, the TCB will tell the Mini to play the repair sound. If you tell the TCB to start the engine, the TCB will tell the Mini to play the engine start sound. You are not controlling the Mini, you just need to control the TCB. If the sounds are in the right places on the Mini, the TCB will take care of playing them when needed, you don't have to do anything extra for that.
It all sounds pretty logical and easy. It's what I love about OpenPanzer
About 10 years ago, I was tinkering with Arduino robots and considered using it for RC tanks as well. Then I've got an eye on the OP project. Unfortunately, when I got ready for it, TBC was no longer in production. This year, I thought, what if I try to use PCBway to get a few fully assembled boards, and it went pretty well.
If you don't mind, or if someone is interested, I can share the link to PCBway, so anyone can order it. I ordered 5 boards, and it cost me around $85 US, including delivery to New Zealand.
So, now I'm building my first two RC tanks
It is sadUnfortunately the later versions of the Teensy do not have the sound capabilities that the 3.2 did, or else I would have been happy to port the firmware over to the new Teensy designs.
