Greetings to Renesas Engineering Community,
Currently I am working on developing a USB interface for my product. The product receives MIDI messages via USB from a PC or a keyboard (musical instrument) .
It does not sends a MIDI message. what are auxiliary connections that come with USB VSS,USB VCC,DP and DM pins (pull up ,pull down resistors ,capacitors etc ) The product is powered by a SMPS in PCB with 3.3V .I want USB to be powered with the same.
Is there some pull up resistors in built in these pins.
Should I use USB isolators if so is there a connection settings I should do extra in that scenario.
Kindly guide me through the process as its my first project involving USB.
