jvolk,

Thanks for you advice, I'll make changes, and I'll try again.

''That's weird..'' I know, but why?, I d' not.

Tanks again.

Moraru.

[jvolk]

Okay... change this when you will have time and report if there will be some success.

[jvolk]

Is anyone interested in my PCBs? I will send drawings to manufacturer, so I can order some PCBs for you. I don't know price yet, but I guess that will be around 10 €.

Jvolk, congratulate!

Moraru, install in chain of the signal Reset external Brown-out Detection, for instance МС34064 ( http://www.microsemi.com/datasheets/mc34064.pdf ) or similar. This must help with zeroizing EEPROM. See the scheme.

Hi arisov77,

Tanks for you advices, I'll make all changes and I try again.

Do you make any progress with new project?

Moraru.

[arisov77]

…Do you make any progress with new project?...

In connection with big utilised capacity on the main work, the work on new variant servocontroller I have temporarily stopped.

[jvolk]

moraru, how did you set Brown-out Detection on microcontroller?

[arisov77]

On my experience turned out to be that AtMega8 more subject to malfunction EEPROM, than AtMega48 or AtMega88. For AtMega8 better to install external Brown-out Detection.

moraru, how did you set Brown-out Detection on microcontroller?

Brown-out Detection is disable.(post #47 in this thread).

[arisov77]

Brown-out Detection (BODLEVEL) it is necessary enabled!
I this shown on picture in post №48.
I do not know that in earl BODLEVEL in JTAGICE mkII (beside me such no). But it is necessary to install maximum importance of the voltage Reset.

I will second using BOD, I am running the original Elm configuration and it used to do nasty things to the tuning parameters every now and then at power off without BOD, set it and never had another problem, machine been running at least a year without incident since then.

Cheers.

Russell.

Thanks Arisov77, u the man.

Can i have the *.asm source code of Servo_Mg48_20Mhz_v3_5 ..?

[arisov77]

Can i have the *.asm source code of Servo_Mg48_20Mhz_v3_5 ..?

Here it is ... with comments in Russian.

[jvolk]

Is there any suggestions or instructions how to set parameters?

Thank you JVOLK.

Hello everyone!

I'm having some problems with jvolk's servo boards. I have ordered PCB's that he had made and populated one board. For a moment everything worked and I was able to control the motor using the servo-tune program. After a while I wasn't able to make a connection between my computer and the servo controller. I also soldered only the MAX232, Atmega88, 7805 and the necessary capacitors, resistors and connectors on a second PCB and I still haven't been able to make a connection. When I connect the programmer I am able to read and program the chip, I have also checked all the connections and voltages and everything seems so be fine.

Does anyone have an idea what could be the problem with my servo controllers?

Best regards,
Primoz

hello all
i have also make elm servo with tiny2313 and ir2104and irf540. i have a problem in testing. some time eeprom earsed on power failer.
please tell me how can i put the velues of p0 to p6 in my code permanently?
thanks

Hello everyone,

I build the driver that you have developed, but I would like to know what the latest version of the driver software, and the last scheme.

I have looked at previous post, but there are many, and I explain no.

Forgive my English, I use the google translator .

Thank you very much for such good work, greetings.

[myown]

i do that, after 5 burning ir2184 and irfp260 I start my driver !
So I propose to show video driver in work!
