/* IR to USB keyboard optimized for KODI openELEC running on Asus Chromebox.
* IR device: Logitech Harmony 880 with remote profile: 'Panasonic TV TX-43CXW754'
*
- * Initial proof of concept.
- *
- * Testing with:
- * - SparkFun Pro Micro, ATmega32u4 (5V, 16MHz)
+ * Tested with:
+ * - Arduino Leonardo & SparkFun Pro Micro, ATmega32u4 (5V, 16MHz)
* - Arduino IDE 1.6.7
* - HID Project 2.4.3
* - IRLremote 1.7.4
*
* ISSUES:
- * - Most promising branch yet :)
* - IRLremote doesn't work with Logitech Plex Remote profile. Now (ab)using Panasonic TV TX-43CXW754 device template.
* - Watch dog reset doesn't work, according to Google this is most likely an Arduino bootloader bug.
+ * - IRLremote doesn't work with MattairTech MT-DB-U4 1.6.9-mt1
