I just installed Ubuntu on an old 2003 dell desktop XPS. It seems like a very nice OS and I like the UI desktop. I have a question about to the possibility of something.
My experience:
First, I'm an electrical engineer just graduated and I have experience programming Java, C and C++ and alittle verilog. Most of my C programming experience comes for programming on smaller machines like micro-controllers and FPGAs and DSP. I'm very good at programming java but my expereince is mostly limited to the fundamental programming concepts of OOP as I have never actually written an application outside of the command prompt (Eclipse). However, I have written a lot in Java and am more than beginner.
I've built,tested and designed a lot of circuitry before and understand how wireless communication systems work.
So my question:
I want to be able to talk to my desktop using a UART chip. I wanted to know how I can write applications on Ubuntu OS that can act as standalone GUI interfaces and interface via I/O ports on my desktop like the USB, Speakers ect. Is there some IDE (For Ubuntu) I need to download that contains the libraries to interface with these I/O ports like USB? So lets say I want to write a program on my Ubuntu desktop that contains just a text box and a graphical button. The function of the program is:
1. Enter a number in the text box.
2. Press the button --> Transmit number over USB to UART.
3. Then the number say 5 ->101 would turn on say some LEDs. Say LED 1,2,3. 1 ->ON, 2->OFF, 3->ON corresponding to the high bits for the number "5".
Thank you
I really just want to learn how to program on a powerful desktop machine and communicate data over USB.
