Hi,
recently I've bought z8 encore development kit, but i have some problem with it.
Every time i touch any of GND,+3.3V, 5V or 9V wires with something made of metal, my system is restarting.
I know, that any signal nets never shouldn't be directly touched, but system ground (or VCC) very often is connected to some sensors, buses, peripherals (the simplest example is ordinary RS232 cable connected to PC). I don't want my system to restart when I just plug the RS232 cable to it.
Does any of you had simmilar problem?
How to deal with it?
Thanks for any suggestions.
regards,
Krzysiek
