Note the following details of the code protection feature on Microchip devices:

• Microchip products meet the specification contained in their particular Microchip Data Sheet.

• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions.

• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip's Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

• Microchip is willing to work with the customer who is concerned about the integrity of their code.

• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products.

1.4 GETTING STARTED WITH THE rfPIC DEVELOPMENT KIT 1

The transmitter modules come pre-programmed with a transmitter demonstration. The enclosed PIC16F676 is programmed with a receiver demonstration program. Together they demonstrate an on-off command and control application.

The PICkit platform for the transmitter and receiver modules.

To see your rfPIC Development Kit 1 in action, perform the following steps:

1 FLASH Starter Kit serves as a low-cost development and demonstration

1.4.1

Preparing the Receiver Module for Operation

Step 1:

Familiarize yourself with the PICkit 1 FLASH Starter Kit operation by reading the PICkit™ 1 FLASH Starter Kit User’s Guide (DS40051) and performing some of the tutorials. Familiarity with the PICkit Starter Kit will be assumed throughout this user’s guide.

Step 2: Remove power from the PICkit Starter Kit by disconnecting the USB cable.

Step 3:

Remove the PIC12F675 from the PICkit Starter Kit evaluation socket.

Step 4: Insert the PIC16F676 into the PICkit Starter Kit evaluation socket. See Figure 1-1.

Step 5: Insert a receiver module (315 or 433.92 MHz) into the PICkit Starter Kit expansion

header J3. Make certain that the receiver module is oriented correctly. See Figure 1-1.

Step 6: Insert the wire antenna into the antenna connector on the receiver module. See

Figure 1-1. The wire antenna length is determined by the receive frequency. For the corresponding frequency, insert the following wire antenna:

Frequency Antenna Length

315 MHz 9-3/8”

433.92 MHz 6-3/4”

Step 7: Power-on the PICkit Starter Kit by connecting the USB cable to a personal computer or

externally powered USB hub.

Note: There is no interaction between the receiver demonstration program in the

PIC16F676 and the personal computer.

The receiver module is ready for operation.

1.4.2

Preparing the Transmitter Module for Operation

Step 1: Select the transmitter module that matches the receive frequency of the receiver

module installed in the PICkit Starter Kit.

Step 2: Power-on the transmitter module by positioning the shunt jumper to the batt position on

P1 (between center pin and batt pin). See Figure 1-2.

The transmitter module is ready for operation.

Demonstration Operation

The demonstration program is a simple on-off command and control application. Pressing push button GP3 (SW2) on the transmitter module lights LED D0 on the PICkit Starter Kit. Pressing push button GP4 (SW1) lights LED D1.

1.5 DEMONSTRATION PROGRAMS AND HEX FILES

Additional demonstration programs are provided on the rfPIC™ Development Kit 1 CD-ROM. Chapter 2 provides an explanation of each program. HEX files and program source code are provided. The HEX files can be programmed into the rfPIC transmitter and receiver modules using the PICkit 1 FLASH Starter kit. The source code can be modified and compiled using the MPLAB software and the resulting HEX files programmed in the same manner.
