accessing RS232 using C/C++
Hi,
I wanted to know how to access hardware (like rs232, mouse, keyboard, usb port) using a C/C++ program. I'm interested in writing a small program to transfer a text file from PC to a micro-controller (or any other device for that matter) connected via rs232! I'd be grateful if anyone can help me out...
Thanks in advance!
Well you need to tell us which OS/Compiler you're using on your desktop machine.
Also, which machine are you asking about - the desktop or the micro-controller.
RS232 isn't mentioned anywhere in standard C, so you need to be specific about both ends of the link.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
salem,
I use both windows xp and ubuntu on my desktop. and i use gnu gcc complier and sometimes use borland.
The microcontroller I'm using is the classic 8051 from atmel.. If any other info is required?
thanks in advance.
For Ubuntu (or any other Linux), try Serial Programming HOWTO
And perhaps 8051 serial port programming for the device.
