TCB Dev / Re: TCB Firmware with Stock Arduino Mega

I have the escs set up as described and I’ve had good experience with them on other projects (rc ships).

Think you might be right with the battery though. I’m using a NiMH battery because discharge rates haven’t been so important to me. I’ve got a lipo on order and I’ll see if that improves things.

Finally found a driver that will connect Dasmikro mini.

Hi Tef, what you describe is very strange and I can think of no reason why that should be happening, and especially why it would occur with both ESCsc but not with one.

There are a couple things which I do not think are the cause, but which would be good to verify. First, both ESCs should have their BEC (+5v) wire disconnected prior to connecting to the TCB, as described in the Wiki.

Secondly, I see these ESCs have multiple driving settings, selected by jumpers on the device. They should be set to "Forward/Backward" mode; in other words, there should be no jumper on position 1 or 2. This lets the TCB handle braking.

As for the behavior itself that you describe, I really have no idea. But one wild guess is that when both ESCs are commanded to perform the abrupt track recoil movement, they momentarily draw more current than your battery can provide, and this causes a brief voltage drop that disrupts the normal function of the TCB processor. One way to test this theory would be to use a battery with a larger capacity and C-rating.

Otherwise the other thing to try would be different ESCs, though that will require spending money.

Anyone able to help with a track recoil issue on an arduino mega build?

I’m using to radio link 9030 escs which work fine when driving. When I use track recoil I have no issues if only one esc is connected at a time. However, if I connect both then the entire system goes hay wire and the track recoil effect fires on a continuous loop until I reset the system. Any idea what could be causing this?

Thanks for reporting the resolution.

Solved:) It was one wrong number on prop setting on the TBS. 153 should have been 157!

Thanks Luke,

Yes more process of elimination lol.
I think it may be something in parameter settings.

To solve these kinds of problems you will have to do some troubleshooting, which requires experimentation with a view to narrowing down the possibilities - an experiment can prove that one part of the chain of events does work, which you can then cross off the list of potential issues; or the experiment can be designed to prove that one piece does not work, and then you know where to focus.

You know your other sounds work when triggered by something other than braking, but that doesn't tell you whether A) Sound 2 actually works, or B) whether braking actually works as a trigger. These are the two things you need to experiment with.

You tried to trigger Sound 2 with the Transmission switch, because you know the Transmission switch works. Sound 2 still didn't play. That would imply to me that the problem is with Sound 2.

What if you tried to trigger your Transmission sound with the braking trigger instead of the switch? We know the Transmission sound works, so in this test you are focused on whether the brake trigger works. Or you could set up a light to come on with the brake trigger, and if that works, then it would be further evidence pointing to a problem with Sound 2. There are lots of things you can try, but only you can try them.

Yes prior I did set momentum to high and brake sound would occur.

Now no brake sound and the odd thing is I have brake sound as 2nd user sound after transmission sound and before a track sound and then 3 squeaks and all those sounds trigger. But when as a test I tried to set sound 2 to trigger in place of another sound that triggers, sound 2 isn't played? It is loaded properly with the right settings into the TBS but sound 2 doesn't seem to trigger? Can't figure it out. For instance, tried to replace the transmission sound with sound 2 on the same switch but nothing?

The "Brakes Applied" trigger really only works if you are operating with a very high level of deceleration (momentum). I see you have Deceleration Level assigned to a variable channel, which is fine, but you need to turn that knob up until your tank coasts for a good length of time. "Braking" occurs when, while coasting, you move the throttle stick in reverse, but not so much as to stop the tank completely, rather only enough to increase the rate of deceleration (ie, cause it to slow down faster than it would if lelft to coast). 

Since our models don't actually coast unless we artificially create this effect, and even then it doesn't last long, the fake braking effect, which is trying to undo our already fake coasting effect, is of even a shorter duration, and it can be tricky to get it to occur. The best chance is to set momentum to the max level, and then get your tank going as fast as possible, before trying to brake gently.
