I'd like to be using the hardware serial ports on my pic's for my current project.
The current project is a PC to TRANSMITTER PIC out wireless to remote side which receives wireless and tranmits back to RECEIVER PIC and then to pc. I'm going to use 2 chips on both sides. Currently I dont believe that i'm utilizing the features of the 2 pic's im using (we'll actually soon to be 4) on the "PC side" im using 2 PIC16F767 chips, currently the remote side is just a single 16F84A @ 4mhz. i'm going to be using 2 P16F872's when i put 2 chips on that side...i know pin overkill, I probobly only require 1, but im trying to keep things as "real time" as possible, and 2 chips yeilded speed inprovements for "the system" so i accepted the method. I'm sure there's ways to do with 1 chip a side, if anybody would like to tell me this, while keeping the system close to "real time" i'd appreciate it. Any good howto's i havent read yet. I'm thinking of attaching my holtek encoders to the other pins on the tx and rx chips, adding tx and rx endoder / decoder and have a switching mode to use the pic to send signals and receive, or the encoders /decoders. I may build some "thing" that i want to have feeding into a holtek chip. I wonder how the pic and holtek chips will handle sharing the antenna's. Oh can i use my same antenna thats another big question to work out. currently the RWS-434's and the TWS-434's have their own antenna's. The TWS-434 apparently can operate without the antenna, but i keep em on anyways. It would be ideal, from a design perspective, if all the rx and tx systems on either side could have 1 antenna for tx rx.
And crystals... 20mhz seems to be what im using (except on the soon to be phased out 16F84A@4mhz). Can we do as Melanie had suggested and hook up the osc pins? ( http://www.picbasic.co.uk/forum/showthread.php?t=575 ) is there a schematic floating around with the exact configuration for the sake of clarity.
Hardware serial ports, how to use those... they'd likely be better that just using 2 pins assigned as the rx /tx and serin2 seriout2. I've got some reading to do....
