In search for a way to send strings to an usb character display from within pd,
I came upon the comport external:
Although a bit outdated, it worked right out of the box, but lacked an
implementation of the print method, although the function header was already
present as a comment in the source.
The only way to send characters was by sending ascii codes as float messages.
Since I don't know how to convert a string message to a series of float
messages, I decided to implement the missing print method.
I also inlcuded the /dev/ttyUSB0-7 devices in the device list, to facilitate
opening an usb serial device, like my Matrix Orbital LK204-24-USB.
The only problem still is that I can't send a message containing comma's,
because the message is then split in two messages. Any suggestions on how to do
Of course, I could also have used the system object like this [system echo
"Hello, world!" >/dev/ttyUSB0], but I also need input from the lcd module, and
the system object doesn't provide that.
Modified comport.c attached. See above url for makefile.
