Introduction

May IR blasters (transmitters) are controlled by PC serial ports. As serial ports become harder to find on newer hardware, USB solutions are needed. This will describe using a USB transmitter from http://www.irblaster.info/usb_blaster.html. Despite what the web page says, the unit I received was NOT an FTDI FT232 based transmitter, but it was based on the better FTDI FT230 chip. It was found that the FT230 chip worked better than the FT232. And despite what the irblaster.info page says, you do not need to compile LIRC to use with Ubuntu 20.04. This page will describe using this transmitter in Ubuntu 20.04, and will also describe using the transmitter in a system that also uses a mceusb LIRC receiver.

Setup

  • mceusb IR receiver plugged into USB port
  • FTDI FT230 based IR blaster plugged into USB port
  • Ubuntu 20.04
  • LIRC version 0.10.1
  • Both IR receiver and transmitter will be handled by LIRC. This means that two instances of lircd will be created by the configuration (reference https://www.lirc.org/html/configuration-guide.html#appendix-9).
