I crashed my 3pi.
2 mistakes … during debugging via serial line I connected ground not die 3pi ground but PB3.
I guess by that I destroy the pin driver.
To check if the driver is still working I load 3pi demo programm …and by that the 3pi jumped off the
table …lost 1 IR sensor, the roller coster and a battery jumped out.
Now I can not flash the 3pi any more. Reading the flash and eeprom seems to work.
Any hint what could be demaged?
LCD first line is light gray. (I think I´ve seen that before if LCD is not initialized)
blue LEDs are shining.
green LED is dimmed.
öhm … do not know exactly what the solution has been …but I reduced the ISP frequence to 1.5 KHz …
did not solve the problem …some strange timeouts with the programmer and a reboot of the
windows box
ereasing without programming …
and than try it again …piep …my toy is back …
…not sure if it is realy made for “Grobmotoriker” like me.
solder the IR …and now everything is fine …including the motor.
the whole storry is a bit strange …why flashing the 3pi-demo prog switched the motors on?
3pi stuxnet?
HW extensions wishlist:
a shelf to protect the 3pi a bit
a parking frame for tests and debuging
replacable 328p ( is there a small socket?)
powersupply from USB // could have been this standard problem? they have been on 4.5V (NiMH)
