nRFready Microphone User Guide
4.1 Pairing procedure
If you want to pair a microphone with another receiver board, or you have a receiver- or microphone board
which hasn’t been paired before, you will need to pair the boards. You can only pair one microphone board
with a receiver board, at a time. Hold in the button on each board until the LEDs on each board blink
rapidly (meaning faster than the normal no-link blinking), then let go.
The lights should stop blinking rapidly once the boards are paired. Some seconds may pass as the boards
reload configuration values. Repeat the procedure if you also want to pair the second microphone.
4.2 Programming boards
If you want to customize the nRFready Microphone, you can program the receiver- and microphone board
microcontrollers using a third-party development tool. The nRFready Microphone uses a PICkit 2
TM
or the PICkit3
TM
. The development tool must be bought separately since it is not included in this
kit.
The boards can be programmed in one of two ways:
•
The pre-compiled HEX files for the microphones and receiver can be programmed directly by using
the PICkit2
TM
programmer tool. None of the boards need to be supplied with external power during
programming, just simply connect the programmer to the ISP header, import HEX and write to the
device.
•
You can also compile and program the boards directly from the MPLAB IDE. Make sure to select the
correct programmer tool from the
Programmer
tab in MPLAB IDE before building the project and
programming the board. Refer to the user guide for the MPLAB IDE available from
http://
www.microchip.com
for further details.
