Propeller Reset With Protoboard
Hi,
I'm trying to piece together a robot using the Propeller Protoboard. I'm having a problem that the propeller seems to reset when I have the servos on while running 2 GP2D15 sensors and have the propeller plug attached...when running off a 6v battery pack. When running off the power adapter, the chip does not reset. Also, the chip does not reset if I remove the PropPlug. It seems to me that maybe too much current is being drawn from the chip and the battery pack cannot handle it. Is there a way that I can modify the protoboard to handle this ? Maybe a larger capacitor ? I'm not much of an electronics guys, so I can use any suggestions....

Go for at least 7.5 V and good continuous current capacity.
Cheers!
Have you seen in the protoboard schematic, that there are two jumper settings for powering the servos?
[font=Tahoma,Bold size=2]IMPORTANT: Servo Power Supply (Vin)
[/font]Use only the Vin jumper setting for powering servos when power is supplied from a 6V battery pack. Damage could occur to your servos if you use an unregulated power supply.
Clemens...I initially had it through the 5v regulator and was getting the reset. I then changed the jumper so that the servos used the Vin from the 6v battery packs (I assume unregulated). This did not seem to make a difference ... the reset still occurred.
I find it strange that having the PropPlug plugged in causes the extra current and a reset. Its weird, because if I run the servos slower, the reset does not occur. Strange...
