lirc ftdi "buffer overflow while generating IR pattern
by Quakeboy02 from LinuxQuestions.org on (#5P3PV)
After resolving the problem I had on the RS-232 lircd setup, I need to setup the other emitter, which is a FT232R. I followed the instructions at the website below. The problem is that it trows a "buffer overflow each time I try to send a change-channel command: "irsend --device=/var/run/lirc/lircd SEND_ONCE clikr5 KEY_EXIT". Is this buffer overflow an indication of a driver bug, or a setup problem? "irsend" command and error result below.
