Hobby project design

Postby NewbeeV-USB » Thu Jan 04, 2018 4:43 pm

Hi I want to design a hobby project which consists of ATmega32, 128x64 KS0108 based graphical lcd and USB port. I am using V-USB as a firmware in ATmega32. My aim is to connect a USB optical mouse to USB port and display mouse pointer on GLCD, as mouse is moved pointer should move accordingly.

I am using Atmel Studio 7.0

1. Which schematic should I use.
2. CPU clock rate (12MHz)
3. Which files to be copied to my project from vusb-20121206 directory downloaded

Hi,

You cannot use VUSB to act as an USB master (e.g. your laptop), it is the implementation of the slave protocol (e.g. USB mouse, keyboard,...). If you want a simple USB master you can use a RaspberryPi with libusb.

Ciao, Martin
