Let me come right to the problem.
I intend to make a small+portable+battery powered AVR Device which has a GLCD (not too big, I shall use 128x64 which I already have) and a few buttons.
What I want is that it should be able to show data received from USART on the GLCD line by line, nothing more, it doesn't need to send anything back but only receive and show text on LCD. The buttons can be used to set the baud rate etc and other such settings.
So, I want to ask where to begin or if someone has already made such a device and posted here (I have searched but failed, maybe I am not searching with the right word). I want to make it using ATMEGA32/16 or even 8, using AVR-GCC in AVR Studio. I already have enough knowledge to start on it, but I wanted to get some opinions from here as well.
The need for such a device is arising that I lack basic equipment like logic analyzers etc and I dont have a scope at home, so I have to rely on USART data and JTAG. but recently I have lost my PC with Serial port and laptops dont come with serial ports anymore, so I was wondering about making such a device.
THANK YOU ALL FOR THE HELP THAT YOU GUYS PROVIDE HERE....
