hi all ,
m designing an application using pic18f4550 . m making usb interface. M unable to connect the link between the controller and usb .i tried putting 220nF to 470nF capacitors on the Vusb pin .the problem is that when i touch the Vusb pin of the controller with my finger the communication starts otherwise there is no communiaction byitself. i tried all possible solution but unable to take out the noise..please help........
one solution to reject noise is to connece a 10k ohm resistor to the terminal that you must touvh by hand and connect the other terminal of the resistor by the ground
