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? dlc kalyanramuv wrote: > 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 > > to unsubscribe, go to http://www.yahoogroups.com and follow the instructions > > ">http://docs.yahoo.com/info/terms/ > -- --------------------------------- * Dennis Clark http://www.techtoystoday.com * * "Programming and Customizing the OOPic Microcontroller" Mcgraw-Hill * --------------------------------- |

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?
Some other links for you:

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
