Hey all..
my final yr project has a subsection that sends data from a PC to a BOX which contains my electronics...
basically i have VB.NET application that sends out values from the serial port... via a USB->SERIAL adapter (emulates a com port)...and at the moment, i have a physical connection of this to my PIC Rx pins..
my PC will be 1 transmitter and i will have 2 RECIEVERS. each reciever will be identical with identical PICs..
so at the momemnt i can communicate via wires to BOTH recievers, BOTH of them recieve ANY DATA...but only 1 of them will read in DATA MEANT FOR THEM (by having a coding system - headers etc)... so im sending HEADER | BYTE 1 | BYTE 2 | BYTE 3 | BYTE 4
that happens every transmission... but as i sed only 1 will understand and store it..
now i want to remove the wires... and have it wireless.. i heard bad things about the 400MHz range.. as its quite busy and told to use the 900MHz band..
so obv i cant use a transiever as i have 2 recievers and 1 transmitter... can i jus get a matched pair and duplicate the reciever ..?
in the end id want 2 way comms so wud i need
@ PC - transmitter FREQ 1 / Reciever FREQ 2
@ R1 - transmitter FREQ 2 / Reciever FREQ 1
@ R2 - Transmitter FREQ 2 / Reciever FREQ 1
Does that mke sense??? HELPPP lol
