The PIC16F877A need to be interface with the SKXBee module or XBee chip because XBee chip design is not in the Proteus 7 Professional library. The microcontrollers that has USART peripheral only can interface with the SKXBee.
Picture above shown the schematic diagram to interface the PIC16F877A and SKXBee (XBee chip). All the connection are right. For the push button, it is depends on you whether you want it or not. This push button is a reset button, its function when you want the microcontroller to reset SKXBee during a run time.
But please remember DO NOT connect USB to SKXBee if it is connected to the microcontroller. SKXBee can only be connected either with USB cable or microcontroller.
salam,
ReplyDeletei have 1 question about xbee interface with uC.
xbee operate with 3.3v and uC operate with 5V
in ur circuit show, pin tx and rx uC directly connect to pin tx/rx (xbee), whether the connection can be made or not even though the uC operates with 5V?
tq
it can be directly connect coz in the XBee board it self had convert the power from 5v to 3.3v..but remember, i used XBee with a embedded board that manufactured by Cytron company..
ReplyDeletebut, if let say u wanted to use a single chip (stand alone chip), u need to connect it to the LM1086 regulator.. LM1086 regulator is to reduce power from 5v to 3.3v.. do check my post under title "component that will use"..
u must remember that XBee chip is very sensitive.. strictly remember that it cannot connect to 5v power at all..if u mistakenly connect it to 5v, ur chip will burn immediately..
thanks for u reply
ReplyDeletehmm,
i need ur help
did u still used the skxBEE?
if u not used it.
i want to buy it, for my
project final project
thanks
shall i know the costs of SKXBEE module that you have used and give me some info regarding the availability of the module at low costs.......pls.......
