I do not know that in earl BODLEVEL in JTAGICE mkII (beside me such no). But it is necessary to install...

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.

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

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...

Michael, good PCB!:banana:

Excuse me, but here (see PCB) I shall not be able You to help, on this no time and I have no desires to install for viewing special programs.

Moraru, I can for You to do the code, where will are unplugged protection from big unbalance.

Visky, if I have understood it is correct translation (beside You there is AtMega88 and You did the scheme from message 13 or 22), that You need the code from 1 messages "Servo_AtMega88_TimerInt".

See message #83.

Moraru what Your results?
