Open Panzer Help / Re: Random turret sound with TCB and Benedini Mini
« on: April 25, 2018, 10:20:33 PM »
I'm running the 9x PWM receiver with the HK PWM to PPM converter, so probably the worst of two worlds?
Yes, ha ha, probably. When I first observed the data for an SBus receiver I was very surprised, though I suppose I shouldn't have been, at how clean the signal is. For those the only variable would be the quality of the pots on the sticks of the transmitter, but with an analog setup (PPM is still analog) there is all kinds of low-level noise in the signal introduced at multiple points in the path from your transmitter to the receiver output.

The signal from your radio is not steady and when it strays past center slightly the TCB thinks you are moving the turret so it tells the Benidini to play the turret sound.

You can try increasing the Deadband setting on your turret channel in OP Config on the Radio tab.

Are you using a PPM receiver? They are usually worse about drifting than the SBus/iBus receivers.

You can watch the drift in real time if you connect your TCB to OP Config and do the "Read Radio" routine. You'll see the channel quivering even though you aren't touching the stick.

The Taigen documentation is confusing for sure. There are apparently actually 4 different slip-ring kits, and the one with the most wires is TAG120628, which has IR and turret MG. They have another one for IR without MG which is probably what you have.

Thanks Jerry, your last description will indeed help and I think you have now boiled it down to essence of the problem. This will save me time because now I know exactly where to look, so thank you. It does seem as if driving really has nothing to do with it, but rather that after toggling the airsoft off the first time, afterwards it will not go back on again correctly.

I'm confident I can fix this when I have some time to sit down and focus and get into "programming" mode, but I might not get an opportunity for another week yet. I'll keep you posted. Thanks again for your troubleshooting help.

Sorry for the slow response. Jerry is right, but specifically, you can combine the following:

MG LED (and the other LEDs along the top edge of the board including AUX, L1, L2, and BRK) share a common +5v signal (listed as POS on the underside of the TCB board). These can be combined with +5v on the IR Receiver, +5v on the HIT LED, and +5v on the high intensity FLASH. Additionally if you are using a servo recoil you can also combine these with the + of the servo connector (middle pin of the three pin servo plug).

There are a few grounds that can be connected but not many since as Jerry says most of the switching is done on the negative side. But you can combine the IR Receiver negative (not the HIT LED negative) and the high intensity FLASH negative together. And if you are using a servo for recoil you can tie the servo negative to these as well.

Additionally if you are using the mechanical recoil/airsoft output you can combine its positive with the positive of the IR LED. This level is equal to battery voltage, not 5 volts, so only those two can be combined, but don't mix them with the positive 5 volts listed above.

The barrel elevation motor outputs can't be mixed with anything.

Anyway that should get you down to 12, but Jerry's point is worth remembering that the IR version of the slip-ring gives you a few extra wires.

Another thing to keep in mind is that the wire gauge on these slip-rings is extremely small, meaning it can't carry much current. This probably won't matter for lights and such but I could see it maybe being an issue with mechanical recoil/airsoft units since the motors in these are pretty much under-powered to begin with.

Additionally, any glitching can also cause problems with mechanical recoil/airsoft units because it can interfere with the brief signal these devices send back to the board to let it know the action has completed. Slip-rings by their nature can easily cause such glitches, so if your mechanical recoil doesn't work try by-passing the slip ring and see if that is the problem.

With regards to the Taigen sound card not turning off - there was indeed a bug which I was able to identify in relatively short order, since it was just introduced a few weeks ago when changes were made to the sound code for adjustments to the TBS Mini. It is very common when a change is made in one place that it has unintended consequences in another, and this was one of those times.

I've posted a TCB firmware update (0.93.03) that corrects the Taigen issue. It also includes my "fix" that I posted for you in the test version a few days ago, I actually don't think that "fix" makes any difference to anything and apparently it didn't since you are still having issues with your airsoft. But regardless you can ignore the test version from here on out.

I will delve further into the airsoft thing later when I have some more time.

It sounds like you have multiple things going on and it's not all entirely clear to me. Let us focus on a single issue at a time and ignore the others until one is resolved, and then move on to the next.

There should be never be a message about settings being "deleted." However if you import an OPZ file from an earlier version of OP Config into a later version of OP Config, your OPZ file may not have certain new settings that have been added since. OP Config may tell you that "not all settings were imported" which is fine, it just means your OPZ file doesn't know about the new settings. In this case you need to import your OPZ file to load all your old settings, then save back over the file you just imported. Now the new settings will be added to the file and you shouldn't see that message again.

Earlier we were working on a lack of synchronization between the airsoft and other effects, but which only happened after driving around. I don't doubt something is going on but I am skeptical that driving around is really the cause, so I was wondering if you could pinpoint the minimum state of things that might reproduce the issue, ie, just turn your tank on maybe with your airsoft on/off switch in different positions and see if the synchronization is missing right from the start, or see if changing the functions from on/off to toggle makes a difference, etc...

I won't have time this weekend to work on anything but maybe next week I can get back to it.

Hi Jerry, you can try this test version of firmware, I sort of doubt it will solve your problem and I haven't had time to test it, but it does fix a very minor bug related to the track recoil.

If it doesn't then I will have to try to re-produce the issue on my end which I can do later when I have more time. I do not think it is likely that driving around is actually the thing causing the issue.

Are you using the airsoft enable/disable functions, or the airsoft toggle function? (Typically that is the difference between a 2-position and 3-position switch respectively). Whichever one you are using, you might try swapping for the other function(s) to see if that changes anything.

Very nice, thanks for the detail. I've some sonic smokers before and I think they're a brilliant idea. Much more simple, and more realistic at the same time.

Open Panzer Help / Re: TCB Power
« on: April 17, 2018, 10:47:07 PM »
You could power the TCB from only a single of your 12 volt batteries. But you would need to be very careful doing this, you need to give the TCB absolute ground and 12 volts. In other words, it matters which of the two batteries you use, if you supply it with relative ground and +24 volts you will have problems. So in other words, be sure you use the "low" battery and not the "high" battery.

The other solution which involves a small cost is to get a BEC (battery eliminator circuit) to power the TCB. The TCB runs on 5 volts but it needs a few volts higher than that to function correctly, most BECs output 5 volts exactly but you can find some with variable outputs such as the YEP BEC sold by Hobby King, and I'm sure there are others if you look around.

Or just get any of the various LM2596 buck converters sold on Amazon, eBay or wherever for a dime a dozen (well, close). These take a wide variety of input voltages and then you set the output to whatever voltage you want (so long as it is less than the input voltage). Feed the converter 24 volts, and just set the output to anything over 7 volts and feed that to the TCB.

You can continue to use 24 volts to your Sabertooth, they don't have to use the same voltage as the TCB so long as they all share a common ground.

Open Panzer Help / Re: Gyro Turret lock function
« on: April 17, 2018, 06:04:28 PM »
The Geko is just a brushed speed controller, it's not clear he's even still selling it, but any brushed ESC (with forward and reverse) would work the same (this one from Banggood would be small and cheap). This would let you use your standard HengLong/Taigen turret drive instead of a servo.

The whole setup would be independent of the TCB. Just set your turret rotation to RC Output, attach the gyro unit to RC Output 3 on the TCB and then attach the output of the gyro to your ESC which then controls the turret motor. But yes, that does require you to buy an ESC.

There isn't really a good way to use the onboard drivers in this capacity. The way these inexpensive gyros work is by modifying a standard RC signal. Because the onboard ESCs are precisely that (onboard), there is no RC signal to tap into midway between the processor and the motor driver chips. Nor are we presently able to read a standard RC signal, which is what these gyros put out. Right now the I/O pins only read analog or digital inputs but not PWM.

Theoretically, it may be possible to program the I/O pins to read PWM (although I'm not sure off the top of my head if we have the processor resources to do this). If so, theoretically, it may be possible to send an RC signal out the TCB, into the gyro, then from the gyro back into the TCB through one of the I/O ports, then use that to control the onboard motor driver. This is all theoretical but I think I it is rather complicated and I am not likely to pursue it...

Very cool, that's a great contribution to the community!

It's hard to tell from the photos, is your smoker driven by the movement of the speaker, or is it still being pushed by a fan?

Open Panzer Help / Re: Big problem with TBS Mini
« on: April 15, 2018, 03:47:35 PM »
It sounds like your Mini has gotten confused. As mentioned, I have had this happen to me before. The sounds wouldn't play correctly even in TBS Flash, let alone when used with some other device like the TCB.

Try my process for loading the sounds listed at the beginning of this thread. Before that it wouldn't hurt to re-flash the Mini firmware so you know you are getting a clean start. Perhaps after the engine sounds, add only a single sound at a time, then test in Flash. It may be you have one sound file the Benedini doesn't like. Try to narrow down the faulty behavior to a single cause, otherwise it is impossible to solve the problem.

I was planning on powering it with the 5.5v BEC off the TBS, so that would go to 2-5VDC and GND on the amp.  The two outputs from the Mini go to the A Plus and A Minus on the board input, and of course I would install a JST male on the board for the speaker to plug into (4 ohms works on this too).  Since A+ and A- are fully differential, it should work?  What do you think?

I'm not an audio design expert and I don't know why Thomas recommends the hookup arrangement he does. What you suggest seems logical enough and you could try it, but to be safe you should ask Thomas first.

Let us know the results. That's a very inexpensive amp and if it made a noticeable difference without much hookup hassle people would be interested to know.

It sounds like you are experiencing multiple problems. Let us focus on the Open Panzer TCB first.

I think Snoop doesnt work.. Look at image attached. In Snoop mode I move sticks and nothing happen.
Snoop works just fine or else you would see nothing. What doesn't seem to be working are your function triggers. Did you run through radio setup? Meaning, did you correctly save the stick centers and the min-max values? There is a whole page in the Wiki including a video to describe this.

In your screenshot I see you have LVC (low voltage cutoff) enabled at 6.6 volts, but you are powering the TCB only from the USB port (5 volts). In that configuration nothing will work until you attach a battery.

Please post your OPZ file for me to examine.
