#99789 - I don't think you understand the issue Responding to: ???'s previous message |
If port0 is used to drive the leds, I doubt if the logic '1' level is causing you problems (you're reading 0xff), I think the logic '0' level will be more the issue as it is sinking the led current. Therefore the logic '0' level will not be low enough. Measurements will confirm. |
