Yea, me too until Gramo posted this..

just reading up on them, the pro version will transmit > 2,400 ft and only costs $32US, check out some range tests here:

 

No, it's basically similar to any other licence free radio modules (as power is restricted by the licence free conditions), but certainly the Xbee-Pro module looks impressive, but it's not using the same frequency as the rfPIC's - and it's using a LOT more power.

My problem with the rfPIC's is mostly how much external circuitry they require, particularly the receivers.

You can always try and get samples...... Thats what I did.


The datasheet says that the output power is around 9-10dB (8-10mW). You can always add a little RF Amp (like a mar-6) to get an increase in Tx power.

Microchips App notes I'm going to use to help are:
AN238 = Tire Pressure Monitoring (TPM) System.pdf

AN826 = Crystal Oscillator Basics and Crystal Selection for rfPIC and PICmicro® Devices.pdf
AN831 = Matching Small Loop Antennas to rfPIC™ Devices.pdf
AN846 = Basic PLL Filters for the rfPIC™ _rfHCS.pdf

TB069 = rfPIC12F675 Transmitter Module.pdf
TB070 = rfRXD0420 Receiver Module.pdf

rfPIC Development Kit 1 User's Guide.pdf

Here is a page from the datasheet showing a "typical" apllication for the rfPIC...

Polkie. I have ordered samples from Microchip. I was going for some DSP Pics next. Maybe I will get two of those as well.

But like Nigel said. Complex extra circuit for the TX/RX. Also for my use it would be remote. I could drop a sealed lead-acid battery on it.

The Xbee-pro has quite a range and you just use serial I/O with it.
So for the extra couple of dollars you save a ton of time.

Just a thought.

 

hai friends do any one done simple project on rfid .if so please mail me.my id is
sasi.s.kala@gmail.com

 

Hi, I have same problem as you.
I am also using the same microcontroller rfpic12f675.
and also using the MPLAB ICD2 for program controller.
but i m not able to program this controller using this ICD2. So if u have solve problem can u send me the circuit to connect ICD2 with microcontroller.
i have done connections mention in microchip site. but still problem comes.
so help me in this matter.

Thank You,
Keyur Parekh

 

hi
can anybody help how to program rfpic12f675 controller using MPLAB ICD2?
and if possible can anybody send me circuit for the connection of mplab icd2 and microcontroller. i need urgently.

 

Read the datasheet. It says how to connect it up and the it should be ok

Look at the date of the thread, you are answering a VERY VERY old thread.

 

Yea it was the Old Me... I think I had more hair then
