Open Panzer Help / problems with sound files on Open Panzer Sound card

« Last post by rockchuck on August 20, 2024, 08:03:41 AM »

Hello
I am having some trouble with the sound files not playing correctly and also affecting control of the tank. I have a set of test sound files downloaded from this site and they work ok in 3 other tanks fitted with tcb and Op sound cards.

The test set of sound files run correctly when fitted to the tank and all functions are ok.
When I fit my own sound files then I have trouble with the working etc. The sound files I have made are configured for 16bit PCM at 44100hz sample rate and the play ok on my pc as wav files.
I have checked the file names on my files and they are correct.

I tried the sound card test with the good set of sound files by placing the jumper on rc1 input on the sound card but nothing played and nothing downloaded to OP config.
I know the sound card works ok. So I don't know why this test mode didn't work.

The only thing I have noticed between the test sound files and my own files is the size. The test files (downloaded from this site ) is 9.61mB however my file is 142mB so I don't know if this is the reason for the odd behavior!
Any help would be appreciated.

thanks

Please let us know the result when you have completed the mod, as others may be interested in doing the same thing. Would you be able to share the link to the product you are using?

Thanks Luke for your reply.
I have ordered some 6 position switches from a UK supplier that already have the resistors (smd) fitted so all I will have to do is attach the 3 wires from the pot to it and all should be good.
cheers

My understanding is that I replace one of the pots with the 6 pos switch.

 My question is how is this identified in OP Config. My thinking is that I would have to use resistors on each position to mark the signal into 6 steps ie from pwm pulse -100% to +100%. Then set this channel in OP Config as a digital chan with 6 positions.

Hi Rock, this method that you described will work with any transmitter and OP Config will be able to read it just fine (as a 6 position digital channel) assuming the resistor values were correctly chosen. As you say, you replace a pot with a 6 position switch and resistors, it basically ends up still being a pot, but instead of an infinite number of positions from min to max, it only has 6. This doesn't require any special transmitter programing, and as far as the transmitter knows it's still a pot. But the transmitter will output 6 evenly spaced PWM values, and OP Config will read those as a 6 position switch if you tell it to.

I have Er9x firmware in the radio and I know you can setup different curves on a analog pot chan to generate a signal at the selected steps on the pot as it is turned. I think these are then described as Logical switches in the firmware so not sure if this is a simple method with no mods to the radio but how would these logical switches be detected in OP Config.

This I am not so familiar with. I think what I recall hearing is that Er9x had some functionality to let you adjust the curve if for example your resistors didn't give you exactly the outputs you were looking for. But I could be mis-remembering. Maybe as you say there is some way to program it so that an analog pot would only output 6 positions. Of course then you wouldn't have the tactile feel of 6 positions, but maybe that's ok with you.

I should say that you can accomplish the same effect already without any mods at all and no transmitter programming. Just assign your analog pot in OP Config to a digital channel with 6 positions (yes, we are telling OP Config a lie, but that's ok).

As you move the pot from one end to the other, OP Config will translate all the infinite values into one of 6 positions, by choosing whatever position is closest to the current PWM reading.  So again, no tactile feel on your transmitter, but you do get 6 positions (or however many you want).

If I misunderstood your second question you can enlighten me further, but at any rate, the first approach using a hardware mod will work.

Hello
I am in the process of modifying my Turnigy 9X AFHDS 2A radio for adding 3 position switches and would like to add a 6 position switch. The 3 pos switch I have worked out however I'm not sure about the 6 pos switch. My understanding is that I replace one of the pots with the 6 pos switch.

 My question is how is this identified in OP Config. My thinking is that I would have to use resistors on each position to mark the signal into 6 steps ie from pwm pulse -100% to +100%. Then set this channel in OP Config as a digital chan with 6 positions.

I have Er9x firmware in the radio and I know you can setup different curves on a analog pot chan to generate a signal at the selected steps on the pot as it is turned. I think these are then described as Logical switches in the firmware so not sure if this is a simple method with no mods to the radio but how would these logical switches be detected in OP Config.

Anyhow if the hardware hack is the only option then that's ok just means getting the right switch etc and doing the mod.

Thanks in advance.
cheers

 Hello

you are right. europe and especially germany for new eletronics is a "hard pavement". you can't imagine what you have to manage to get a license for selling and also for the usage. there can happen so many things and it's necessary to exclude all this "possibilities".
means for your usage you do not need them but if anything happens, for example the pacemaker from your neighbour explode because you are driving with your tank with an OTB inside through your garden ;-)

What do I need ferrite cores for?

You don't need them, and I can't help but find their inclusion humorous. But that is one of the consequences of production and certification in the EU.

Yes, but just think, you also get three ferrite cores!

I've never needed them together with a TCB...

The board from Torro is expensive - really expensive => 169,-€ this is three times the price of HobbyKing
The scope of delivery only includes a usb cable.....no other cables!

Hello Luke,
I am still using TCB....
Mostly homemade ones for space reasons.
However, in tanks with enough space I use Beier SFR-1-D.
