Nybble (NyBoard v0_2 + RasPi 3) was running now for several weeks without any problems.
Today something happens:
- Nybble was directly connected to my external power supply and RasPi was connected with USB (I used this configuration in the past few days without any problems)
- I called "./ardSerial.py khi" from RasPi and Nybble started greeting
- During greeting suddenly the cable of the external power supply drops out
- Followed by an undervoltage meow I disconnected everything and tried to restart
Now Nybble doesn't boot up when powered.
No servo moving, no rgb led, no initialize beep, no undervoltage meow, only the buzzer hums arround in an annoying constant frequency.
What should I try next?
Burning the bootloader, checking something on the Board or ordering a new one?
poor you have you fixed it yet!!
Calibration values were gone and i had to write instincts again, but now my cat is alive again and i can go on with my project. Thanks!
try to re-upload the module test codes to locate possible damages portion of the board. Test the logical parts first without external power, then the test the servos with power. If it passes all the tests, redo the setup procedures (WriteInstinct.ino then Nybble.ino). Enter ‘Y’ to all the porompts.
