User Manual

Diagnostics and Feedback Parameters

There are two configuration parameters used to setup diagnostics and user

LED feedback which are outlined below.

1. Set Debug Mode

– Setting the debug mode allows the host

application to configure what debug information gets displayed on

the three mode pins when the mode pins are in their default state.

The default state for the mode pins is that none of the pins are

externally pulled-down. The intent of the debug signals is to allow for

monitoring on an oscilloscope how the device is operating.

2. Set LED Functionality

– This message is used to configure if any

LED feedback information is enabled or not, and if it is enabled what

it represents. For modules that are embedded in an enclosure, the

LED functionality can altogether be disabled to further reduce power

consumption. Several examples of the types of functionality that can

be displayed on the LEDs are a heartbeat LED flash to indicate the

microcontroller is running or flashes when an RF or serial message

is either transmitted or received. Multiple functions can be enabled

simultaneously. The LED functionality can be enabled on pins P0_0

and P0_1 or on P0_2 and P0_3, or it can be disabled altogether and

then the pins can be used as user I/O. If LED functionality is

enabled for use on P0_0 and P0_1, either LEDs can be populated on

the Matrix modules itself, or off board LEDs can be utilized. When

LED functionality is enabled for use on P0_2 and P0_2, then it is

required that off board LEDs be used.

Example configuration

The following example will show details of what host protocol messages a

host device would send to a Matrix module to configure all of its

programmable settings. After all of the settings have been sent to the

transceiver, save configuration parameters message is issued to save the

settings to non-volatile memory.

LED Functionality: Heartbeat and flash on RF activity,

LED activity on pins P0_0 and P0_1
