Infrared Communications using PIC - kalyanramuv - Nov 9 22:00:00 2003


Hi all,

I am working Infrared Communications between two Pic's.
I am new to PIC.

Can anybody help me with the driver for MCP 2155 in assembly level
program using PIC16F877.

I would be very thankful to you.

Any help on using MCP 2155 code using PIC16F877 would be greatly
appreciated.

Thanks,
Kalyan

Jeese,

IRDA just to comm between two PICs? What type of data rate do you
need and data security and reliability? That is a pretty heavy weight
protocol to support. I've gotten reliable IR comms between two PICs
with nothing more than an IR LED and a PNA4602 demodulator at 2400
baud - up to 3 feet without lenses or amps. w
What are you looking to do?

Re: Infrared Communications using PIC - kalyanramu vemishetty - Nov 10 11:38:00 2003

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.

Thats a tall order! might actually be easier to use this http://www.maxim-ic.com/appnotes.cfm/appnote_number/631/ln/en rather than a PIC based circuit. Although it only has max data rate of about 230kbps. 1mbps seems rather high, what are you monitoring with the DAQ?

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
