#85719 - Glitches? Responding to: ???'s previous message |
Mahmood said:
Any other suggestions or debugging techniques to try out? What happens on Vcc and signal lines (to and from LCD) when you depress the reset button? Can glitches be seen? Does your reset button cause any peak currents, when being depressed? These could contaminate your ground and cause some trouble. Could also be an ESD problem? What happens if you touch parts of the circuit? Kai |
