Revision as of 14:04, 3 July 2016
I have a Honeywell MM14CCSBB (this may also work with MM14CCS). I want to build a device that can control it via internet. It comes with an infrared remote, so I need to make my device send out the same protocol as this remote.
Code Basics
All observations was done using a IR demodulating receiver that is active low open drain. When it outputs a logic low signal, it means the infrared LED is emitting.
The code is a series of bits, 1 or 0, which seems to be code that is LSB first.
All bits are precedes by a low period that is the same length regardless of if the bit is 0 or 1. The bit is indicated by the length of the high period following, short means 0 and long means 1.
