The MAC Sample Program2 : LED Control
The MAC Sample program 2 is developed to provide with another simple example
to construct a star network utilizing the IEEE 802.15.4 PHY/MAC standard.
The MAC Sample Program 2 offers,
1). Designation of a network coordinator in a star configuration
2). If you push a switch on the n th end device, an LED on the coordinator board
blinks on and off n times.
To use the MAC Sample Program 2, you need to prepare one PC with a USB
interface and two TK-78K0R/KG3+UD boards or more boards, up to 5.
The MAC Sample Program 2 is provided in the form of the C source codes with
the MAC library.
If you wish to tailor the sample program to meet your specific experiment, you can
edit the source code, re-compile it with debug build to generate a load module file,
then, start the debugger to load the tailored execution code on to the
microcontroller for further debugging on the project manager PM +. In this
procedure, the Flash programmer is not required. However, because the USB
connection is occupied for the debugging interface, the USB connection is not
available for applications. In this application example, Hyperterminal with USB
connection offers information on the network association. However, the LED
operation can be made without Hyperterminal. Therefore, you can use the USB
connection for debugging for the LED operation. Alternatively, you may make a
release build to achieve a new hex file, on the project manager PM +.
As a general remark, please respect your local regulation of electro-magnetic
emission. In general, it is suggested to use the TK-78K0R/KG3+UD board in a
radio anechoic chamber.
