Ncurses and reading from serial port in C

Post the error message. We can't see your Xcode window from here.

Google AMSerialPort

AMSerialPort is an Objective-C library for using serial ports. It's open source under the BSD License.

I know you asked for C, but AMSerialPort uses the C IOKit functions in its implementation. If it's too much work to rewrite it, you can write C functions that wrap AMSerialPort and then call those from your C code.

 

Couldn't one simply open a /dev/ttyxxx file from a C program to use the RS-232 port?

 

I know that this is kinda offtopic but, why won't you use a Cocoa Application to display the data?

Knowing that there is a Library to read from serial port, you'll rid of complications about ncurses

I'm starting with Arduino, it's a great device!

 

you can just use standard posix functions in c to read/write from a serial port.
Your device should show up as /dev/tty.something
I haven't figured out how to use nonstandard baud rates yet though. Because of that, I can't gather data from my hardware using the fastest settings (my hardware goes up to 921660 baud).

I used this page to learn how to work with serial ports:

It should serve you well.

 

Hello, I need to develop an XCode app able to use the serial port ON THE iPHONE. I already arranged the physical connection, jailbroke the iphone, installed minicom and so on, and I can see on the little mobile terminal app (cydia) the characters sent from arduino.
But I need to read these characters from my XCode app.
Is everything you wrote here still true? Can I use AMSerialPort or is it only for Cocoa desktop?
Thank you!
