cristea 2:4576fcd93ffd 2 * Low level infrared transmission
cristea 2:4576fcd93ffd 3 * This library provides a low level interface to send IR commands. in principle
cristea 2:4576fcd93ffd 4 * other higher level IR type remotes could be build on top of this. I wrote
cristea 2:4576fcd93ffd 5 * this code to send IR commands to a Nikon camera, which it works rather well
cristea 2:4576fcd93ffd 6 * for.
