Need help interfacing atmega8, usb and lcd
« on: September 07, 2010, 12:58:07 AM »
Dear all,

I am currently a second year electronics student at my university. For the digital lab mini project, my group together with 4 others is supervised by the dean. He gave us a pretty interesting topic. His topic was to:

1. Generate a variable sinusoidal wave.
2. Capture the analog data on a microcontroller.
3. Send the data to a PC through USB.
4. Send the data out to a microcontoller through USB.
5. Display the frequency of the sine wave on a LCD Display.

Well, this is a very interesting project for us, however there is one problem. We have not learned anything on microcontrollers yet in our syllabus, therefore, most of us do not know anything on how to finish the project. I myself, have played with microcontrollers in my free time, so I have a little understanding but not enough to complete the task at hand. So, I kindly seek help from the experienced users here on what to do in order to finish the project. I plan to use atmega8 and a 4x20 LCD module because I have one lying around. I am more concerned on how to send and receive data through USB. How do I program the host software? And what do I really need for USB to work? I understand I need a driver if I am not using a HID class. Again, I am a total beginner on the subject, please help me. Thank you.
