oPossum 1,083 Posted May 26, 2011 Share Posted May 26, 2011 The following posts describe a simple method of CIR capture that can be done with almost any MSP430. The prototype shown uses the Launchpad with a MSP430G2211. This device that will show in detail the signal sent by IR remote controls. It measures the carrier frequency, on duration, off duration, and pulse count per burst. The Launchpad fitted with a MSP430G2211 running at 1 MHz sends all this information to a PC where a Windows program is used for graphic display. Capture is done in real time and there is no limit to the duration. The following screen captures are from a remote using RC5 and another using NEC protocol. The top line shows the carrier frequency and a summary of the first 300 milliseconds. The following lines show the details - on duration, off duration, and pulse count. How does a 1 MHz G2211 do this? More info soon... Kman 1 Quote Link to post Share on other sites
