#107388 - standard design Responding to: ???'s previous message |
I designed my board according to Atmel typical schematic. Put resistor 27ohm on pin D+ & D-, and 1k5 between pin D+ & Vref.
I don't have other basic information about designing this USB pin. May be somebody can give another schematic or standard designing rules? Gde |
