#55603 - RE: parallel cut crystal VS series cut Responding to: ???'s previous message |
no,it is not the problem of crystal,either the chip,
both of them are required samples dirctly from original manufature.and in fact i build up 2 identical systems,none of them could work. i read an article from the chip company,suggest that when using an A-T cut crystal,a drive limiting resistor MAY be need between osc2 and one pin of crystal to get the specified frequecy, but it doesn't suggest a typical resistence value for a 16M crystal.and i also wander even if i found the correct value resistor and connect it,will the system work? |
