2.7
XMIT_TEST
This program implements two tests that can be used to verify RF performance of the rfPIC
Development Kit transmitter modules using a spectrum analyzer and calibrated antenna.
The tests start when the indicated push button is pressed and stop when the push button
is released. The processor sleeps between tests to conserve battery power.
2.7.1
Peak Power Measurement
Press push button GP3 (SW2). This test generates a constant unmodulated output for
measuring peak output power. This test can be used for regulatory pre-compliance
testing and antenna tuning.
2.7.2
Data Modulation and Bandwidth Measurement
Set potentiometer GP0 in one of four quarter positions to choose maximum, high,
medium, or low speed signal rate. Then press GP4 (SW1) and fine adjust potentiometer GP1 for the desired signal rate. The signal is a square wave and does not exactly
match the PWM or Manchester spectrums, but is quite useful to determine system
performance. Table 2-1 demonstrates the approximate signal rates. Note that
increasing the analog voltage decreases the signal rate and that the NRZ bps is double
the modulation frequency.

PRESENTATION PAL
The Presentation Pal application turns your rfPIC Development Kit 1 into a wireless
slide show presentation helper. By pressing the push-buttons on the transmitter
module, the commands are converted to page-up and page-down keyboard
commands for a personal computer. There are two programs required for this
application.
2.8.1
USB Firmware - pres_pal.hex
Step 1:
The first step in converting your rfPIC Development Kit 1 is to program a blank
PIC16C745 8-bit CMOS microcontroller with USB (not included with the rfPIC
Development Kit) with pres_pal.hex. The PIC16C745 is a one time programmable
(OTP) microcontroller and can be programmed on a PICSTART® Plus or PRO MATE®
II programmer.
Step 2:
Remove the PICkit 1 FLASH Kit programmed PIC16C745 from socket U1. Insert the
PIC16C745 programmed with pres_pal.hex into socket U1.
© 2003 Microchip Technology Inc.
Preliminary
DS70093A-page 11
rfPIC™ Development Kit 1 User’s Guide
Step 3:
Remove the PIC12F675 microcontroller from the evaluation socket. Insert a wire
jumper between pins 9 and 13.
Step 4:
When the PICkit Starter Kit is plugged into the personal computer USB jack, the
program will enumerate as a keyboard.
Button presses on the transmitter module are interpreted as page-down, page-up and
Alt-Tab keyboard commands. Page-down advances the slide. Page-up goes
backwards in the slide presentation. When both buttons are pressed, Alt-Tab alternates
between active programs.
2.8.2
Transmitter Firmware - prespal_xmit.hex
This program sends button press commands to the receiver. The button press
commands are interpreted and sent to the personal computer as page-down and
page-up commands to advance or retreat the slide presentation running on the
computer.
This program is a slightly modified version of xmit_demo.asm. This program sends a
different count value for each push button press. This allows the receiver to delay
advancing the slide if the push button is pressed for an extended period of time. The
receiver will delay advancing a few seconds if the push button is continuously pressed.
This is similar to the key press auto-repeat feature of many personal computer
keyboards.

Antenna Connection
The antenna connection is a 0.055 inch pin receptical. A simple small diameter wire
(AWG 24) antenna can be constructed and inserted into the receptical. The length of
the antenna wire depends on the frequency.
λ (meters) = c / f (Hertz)
where
c = 3x108 = speed of light (meters per second)
f = receive frequency (Hertz)
λ = wavelength (meters)
The length of the antenna wire in inches can be found for a given frequency using the
following formula:
wire antenna length (inches) = 2952.8 / f (MHz)
Alternatively, the pin receptical can be removed and an alternate antenna connection
can be made. For example, a coaxial wire can be connected to the antenna pad on the
front side of the PCB and ground pad on the back side of the PCB.

rfPIC™ Development Kit 1 User’s Guide
4.3.1
Power Requirements
Pwr Sel jumper P1 selects one of two power sources for the rfPIC12F675:
• PICkit™ Starter Kit position (pins 1 and 2) – placing a jumper in the PICkit position
allows the transmitter module to be powered from connector P2 pin 13. When the
transmitter module is plugged in the PICkit expansion header J3, the transmitter
module is powered from the PICkit Starter Kit.
Note:
When programming the transmitter module in the PICkit Starter Kit, the Pwr
Sel jumper P1 must be in the PICkit position (pins 1 and 2 jumpered).
• Batt position (pins 2 and 3) – placing a jumper in the batt position allows the
transmitter model to be powered from the lithium coin cell battery. When powered
from the battery, the transmitter module can be used in portable operation.
4.3.2
Programming the rfPIC12F675
The rfPIC12F675 can be programmed by the PICkit 1 FLASH Starter kit.
Step 1:
Remove the PIC16F676 or PIC12F676 from the PICkit Starter Kit Evaluation Socket.
Step 2:
Plug the transmitter module into the PICkit Starter Kit expansion header J3
(See Figure 4-2).
Step 3:
The internal PIC12F675 in the rfPIC device now becomes the target programming
device. Operate the PICkit Starter Kit in accordance with the steps outlined in the
PICkit™ 1 FLASH Starter Kit User’s Guide.
The transmitter module can be removed for stand-alone operation. Remember to set
the Pwr Sel jumper for each mode of operation (See Power Requirements section
above).
Note:
4.3.3
There will be some interaction with the LEDs on the PICkit Starter Kit and
the rfPIC12F675. If the user desires, the LEDs can be removed from the
circuit by clipping resistors R5, R6, R7, and R8.
Optional 8-pin Socket U2
Socket U2 is an unpopulated 8-pin DIP connection on the transmitter module. A
user-provided 8-pin IC socket can be soldered in place.
To use socket U2, the user must disconnect the internal PIC12F675 PICmicro®
microcontroller internal to the rfPIC12F675 device from the circuits on the module. This
is done by cutting six PCB traces marked by silk-screened “x”.
Socket U2 can be used for:
• In Circuit Emulation (ICE) with an MPLAB® ICE-2000 and ICD2.
• Inserting an 8-pin DIP version of the PIC12F675. The DIP PICmicro microcontroller
can be programmed externally (such as a PICSTART® Plus or PRO MATE® II) or
internally via the PICkit Starter Kit.
A detailed description of the rfPIC12F675K/675F/675H microcontroller with UHF
ASK/FSK transmitter is provided in the data sheet, DS70091.
A detailed description of the rfPIC12F675K/675 transmitter module antenna design is
provided in the application note, AN868.

FREQUENTLY ASKED QUESTIONS
5.2.1
Devices on the PICkit Starter Kit have no power?
Question:
I see the green POWER LED lit and the yellow BUSY LED extinguished, but there’s no
power to the rfPIC receiver or transmitter module. What is wrong?
Answer:
The green POWER LED tells you that there is power supplied to the PICkit Starter Kit
from the USB cable and that the programming side of the PICkit Starter Kit is powered
(the PIC16C745). The yellow BUSY LED tells you if power is being supplied to the
device under test. Since you mentioned that the yellow BUSY LED is extinguished, this
says that there is no power to the device under test.
Make sure that the DEVICE POWER checkbox (Figure 5-1) on the PICkit GUI is
checked. This feature allows you to control the device under test power from the PICkit
GUI.

Programmer Not Found
Question:
When I disconnect and reconnect the USB cable, and I click on the WRITE DEVICE
button, I receive a “Programmer not found” status message (see Figure 5-2).
Answer:
The PICkit GUI has lost communications with the PICkit Starter Kit. Simply click on the
WRITE DEVICE button again and the GUI should re-establish communication with the
PICkit Starter Kit.
If this condition persists, check that the PICkit Starter Kit is receiving power.
