#168807 - It's easier if he has one ... Responding to: ???'s previous message |
Don't you think he'd have checked that by now if he had a continuity checker? Of course, if he had one and only looked for a short to GND, he'd be blocked too, if it was open, e.g. wired to the wrong pin. That, of course, opens another "can of worms."
Some of these guys don't have much equipment or even access to it. All we know he has is the ability to write to his LCD and observe the result. RE |
