Hey shawn,

Thanks for your reply.

You really answered my question to the point.

I figured out that we cannot use MCP 2120 as it can transmit at 115.2kbps.

I would be very thankful to you if you can give some more information on how to get these high baud rates.

Thanks,

Kalyan

Subject: Re: [piclist] Infrared Communications using PIC

Hi Dennis,

Thanks for you reply. I am looking for higher data rates of 1Mbps.

I am not that concerned about security issue.

I want to transfer data from DAQ module to my computer using two PIC's and a Serial Port.

I just need a little bit of help and a sample code to proceed further.

I am using PIC16F877.

I would be happy if you can help me with the details of your project and code.

Once again, thanks for your reply.

Thanks,

Kalyan

Very high data rates. My code won't help you as it is all bit-banged serial over simple modulated IR LED. I'd be interested in hearing how this all comes out though.
