CCS/MSP430FR2111: How to decode NEC IR remote control data using MSP430FR2111 MCU.......

Hi Nilesh,

I am looking further into this and will provide more info as soon as I can.

Thanks,

Mitch

Hi Nilesh,

What is the amplitude of the pulse train from the IR receiver? Also, what is the supply voltage to the IR receiver?

Thanks,

Mitch

Hello,

Amplitude of  pulse train is  3.2 v and the supply voltage is 3.3 V ......

Thanks,

Nilesh.

Hi Nilesh,

Thanks for the response. I imagine that in order to detect the pulse train your solution would involve setting a GPIO pin as an input to detect the pulses and timers to determine the lengths of the pulses.

Here are some resources that may be helpful to you:

Hello,

 sorry for late reply.

 Thanks for your reply. Here IRremote signals not detect from MCU.. MCU not decode the IR signals . GPIO Pin all ready set to input pin to detect the pulse . I set to flags for  determine the length of pulse ... but finally not detecting the pulse from MCU...  i am trying to detect signal... please any idea and suggestion...  I refer the above App note (slaa644b.pdf), it little bit helpful but not decode the pulse using MCU.

Thanks,

Nilesh.
