Hi, I am using a GPS receiver in my project. It uses a serial interface to connect with the board. I am using a Mini2440 board running Qtopia OS. I want to know how to take serial data from this GPS receiver and store in a file on my board? Is there some serial monitor that I can use in Qtopia? Basically I want something like Ubuntu's minicom for Qtopia. Thanks.
what receiver? may i try in PC?
Write a C program to open a file and read to it from the serial port. Close and save the file when finished. How are you going to interpret the file? Do you have an application that takes this information and then displays it is some human-readable form? What is minicom going to achieve for you, unless you can parse the output "on the fly"?
You can cross compile picocom for mini2440, i'm using it. http://code.google.com/p/picocom/
I tried running it on PC. Minicom gives an option of capture through which you can read the data from your serial port and save it in a file. I want to do the same on my Mini2440. @TungPham, all I need to do is cross compile picocom for Mini2440 and it will work? Without making any changes in the source code?
@davef I tried running its USB interface version on my PC and it gives data in the form of strings on which I can run a C code to extract the data of my choice.
@TungPham, Hey I am not able to download the source from that site. Could you please give me some other link from where I can download the same? Maybe temporarily host it on a sharing site. Thanks.
Tarin, Just checkout it from svn, uncomment # CC and #LD in the Makefile, modify to your toolschain and build svn checkout http://picocom.googlecode.com/svn/trunk/ picocom-read-only tungpt2@tungpt2-desktop:~/picocom-read-only$ make arm-linux-gcc -Wall -g -DVERSION_STR=\"1.7\" -DUUCP_LOCK_DIR=\"/var/lock\" -DHIGH_BAUD -c -o picocom.o picocom.c arm-linux-gcc -Wall -g -DVERSION_STR=\"1.7\" -DUUCP_LOCK_DIR=\"/var/lock\" -DHIGH_BAUD -c -o term.o term.c arm-linux-gcc -g picocom.o term.o -o picocom tungpt2@tungpt2-desktop:~/picocom-read-only$ file picocom picocom: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.14, not stripped tungpt2@tungpt2-desktop:~/picocom-read-only$ Regards,
TungPham, Thanks a lot. Cross compiled it using arm-linux-gcc. It generated 3 files - picocom, term.o, picocom.o I transferred all the 3 files to the tmp folder of my board and tried executing picocom. But it says 'no port given'. How to resolve this issue?
Tarin, Try to use: picocom -b <baudrate> <dev file> For more information try: picocom -h
@tarin how u used arm-linux-gcc ? i try install to picocom but i dont know. is better in usb estract the file and compile? and sry for my english :/
