Hello,
I use RT-Linux to command a video tape recorder. I send a
command to this device, and i have to wait 5 to 10ms for an
acknowledgement.
At the beginning, i used an active wait (
"while(rt_com_read(.....) < 0);" ) but it was waisting a lot of time.
So, i add some functions to rt_com to set an handler function,
only called when something is received by the serial port.
Now, my real time task, send a command to the video tape, make
itself sleeping, and wait to be waking up by the special function called
when somethings is written in the serial port.
I would like to know if there is a more simple and more clean
solution. Does someone developp a version of rt_com able to do that ?
Another question: what is the correct procedure to install the
new rt_com module given yesterday by Jochen Kuepper ?
Thank you.
Julien Verchere.
