The following are the steps to set up a wireless Bluetooth node:
- 1.Connect the RN4678 PICtail board’s PICtail Header
J1 to the PIC18 Explorer Development board’s J3 connector.
- 2.The following figure illustrates the position of
jumpers and switches on the PIC18 Explorer board. Set the jumpers/positions on the
PIC18 Explorer Development board as follows:
- Remove the JP3 and connect J7
Pin No 10 (RH0) to JP3 top side pin
- JP1 to enable LEDs
- J13 to ensure that
communication is routed through the RS-232 socket
- J4 to ensure the Main PIC is
programmed
- Switch S4 to enable Processor
In Module (PIM) (pointing towards MPLAB REAL ICE In-Circuit Emulator when
ON).
- 3.Use the switches (S1 and S2) and LCD
(LCD1) on the PIC18 Explorer Development board for configuring and monitoring the
wireless terminals.
- 4.Connect the programmer or debugger
(MPLAB REAL ICE In-Circuit Emulator, MPLAB ICD 3 or PICkit 3) to the PIC18 Explorer
Development board.
- 5.Plug-in the 9V power supply to the
PIC18 Explorer Development board through the 9V adapter (wall power) or through a 9V
battery, as illustrated in the following figure.
- 6.Open the downloaded application demo source code and compile it. Alternatively, in
the download folder, use the precompiled
RN4678_MCU18_Interface.X.production.hex
file.
- 7.The generated or precompiled
RN4678_MCU18_Interface.X.production.hex
file can, then, be
programmed into the two wireless nodes A and B using any of the Microchip devices
supporting the PIC18F87J11.
- 8.The boards are now ready to run the
demo. In some instances, it is necessary to run a Hardware Reset to run the code,
specifically in the case of the PIC18 Explorer Development board.
Notes:
- Only connect the 9V
battery supply to the PIC18 board if a battery socket provision is made,
as illustrated in the following figure.
- For the application demo,
use the 9VMN1604 (9V-6LF22, alkaline manganese dioxide) battery.
For additional information on programming/debugging with the MPLAB ICD 3, refer to the
MPLAB® ICD 3 In-Circuit Debugger User's Guide for MPLAB X IDE.
