Progamming help with FSBus dll

[RobiD]

Hi Stefan,

Here is a further update to my problem.

I have now reflashed every chip in my collection.

Everything is now working well.

If for some reason I remove the 10 pin cable from the servo board and plug it back in, even if nothing else in plugged in, it takes on the CID of 27.

I tried to set the CID on the servo board without the jumper set (incase there was a short) and it would only reset with the jumper (as it should be).

Do you have any idea how this board can be changing it's CID on it's own like this?

It is very strange, and why 27, why not the default 31?

I look forward to your feedback (or anyone elses if someone has come across this before)

Regards
David

Hi David,

yes have an idea what is happend.
But at the moment the way is not verified.
We talk by PM.

If the controller is resetting this often, I must have a fault somewhere.

What type of events will cause the controller to reset?

Could this be a power supply problem? I am using a Computer power supply to provide power to the servo board and it is also supplying the power to the Com board, a couple of 12vdc computer ventilation fans and a couple of other things.

I also sent you a PM in response to your PM.

Thanks again Stefan, you are always a source of good knowledge and help.

Hi David,
now we go on the way of the solution.
What i write to you, has enable a low Voltage protection. Your 5V Power goes lower than 2,4V that is one reason why the CID will be reset. Now that don´t happend anymore but the complete Controller makes the reset.
You drive the Servos with the same Power??

Please check your powersupply system maybe it have to less power.

Hi Stefan,

Yes, I do use the same PSU for the Com and the extra power line for the servos.

When you say "if the 5vdc power goes less than 2.4vdc" are you referring to the power coming from the com board through the 10 pin connector to the servo board or do you mean from the additional power line coming onto the servo board.

I have not yet tried your suggestion in the PM you sent.

Could I reprogram the code so that all servo commands are to contoller 27 and make the servo CID27 and change the DIO to CID25.

Is this a basic work around that should work long term?

Thanks
David

HI,

ok. i thought that you set the options. The Resets of the IC´s would be the result.
Yes i mean that you use the Power for the Servos over the Com Card.
You can plug the power direct to the Servo Card.

Hi Stefan,

I haven't set the options you have given me in the fuse bits yet.

I wanted to check if changing the CID's I use in the programming so that the Servo card is 27 (so when it resets, it doesn't change everything) would be a simple solution before I tried the fuse bits option and possibly cooked my chips.

I have a seperate power line which supplies 5vdc to the servo from the same power supply I use for the Com board (also 5vdc)

I am willing to give the fuse bits option a go if you feel this is the best solution. No, I won't hold you responsible if I cook the chip (I will just set the servo board chip and see how it goes).

Thanks
David

I would try to set the Fuses, it is a protection against problems like losing CID. if you need i can make a screenshot of the Fuse Bit window in Ponyprog.

Thanks, I would appreciate the screen shot just to be safe.

Hi,

i send the Screeshot by Mail.
