Hello,
I have been trying to set up communication between an MSP430 and my computer (running Ubuntu). I have had two problems with using the serial ports (one for each of /dev/ttyACM0 and /dev/ttyS0). Note that I doubt the problem is MSP430-specific.
/dev/ttyS0
The first problem arises when I tried to connect the MSP directly to the motherboard serial port.
I get this error when trying to connect to an Arduino through a USB serial connection. I'm using the Arduino IDE 1.0.1 and the 64bit version of Ubuntu 12.04. This has been a reoccurring problem since 10.04 and happens to a few other programs that use a serial connection too. I have no problem getting serial data from the Arduino using Python or Screen.
I'm on linux and for some reason I can only use the serial port while screen is monitoring it. When screen is not running, the python code doesn't crash or something. The arduino just doesn't respond. Is there something I'm missing?
I'm working on embedded ARM platform, Slackware.
My termios setup is modifying the first character read from the serial port using read(). I have a microcontroller talking to a linux box. The microcontroller responds to commands sent from the linux machine. The setup is as follows:
microcontroller(PIC24F) RS485 port <--> RS485 to USB converter <--> Ubuntu PC.
When I run a terminal program such as Cutecom everything works as planned.
I have a prebuilt image of Linux (uImage-da850-omapl138-evm.bin) from Arago Project.
So uImage and root filesystem are situated on SD card of my device (OMAP-L138 Experimenter Kit). After Linux is booted, on the screen of this device I can see a screen saver. But input/output runs through serial port.
I got a brain smashing problem with Fedora 16 and my serial port.
I use the serial to monitor an STB on which I'm developping.
Hello everyone, this is my first post and I am by no means a unix expert, so I hope I explain my issue well.
I'm on a mac (mac mini), 10.7.
My question is about serial port names.
I'm using PHP and the php_serial.class.php library to talk to a Teensy (an Arduino clone with a native USB port). I've got it working fine with one issue.
I have to set the access permissions to the /dev/ttyACM0 device every time I plug it into the CentOS based server. (chmod o+rw ttyACM0) How do I make this change permanent?
