Detailed Description

Simple utility to configure the ZNP to output an RF test signal.

Configures ZNP interface, resets radio, and then processes typed commands. The ZNP can output either an RF carrier signal, or random modulated data. The user can change which test mode to use, channel (11-26), and turn off the transmitter. This utility can be used for radiated emissions compliance testing or tuning the RF circuit.

The Utility can be controlled through the simple command-line menu. See printUsage() for available commands. If, instead, you would like it to output one particular mode on startup, change rfTestMode and rfTestChannel accordingly.

Note:: if ZNP_INTERFACE_VERBOSE is defined, this will display an error because the SYS_TEST_RF method does not return an SRSP. This error can be ignored.

Function Documentation

void handleDebugConsoleInterrupt ( char rxByte )

processes bytes received on the debug console

Method to handle bytes received on the debug console. Just stores it to the variable command. This gets called by the ISR in the hal file since we set the debugConsoleIsr function pointer (in hal file) to point to this function.

Variable Documentation

char command = NO_CHARACTER_RECEIVED

the command that was entered by the user

void(* debugConsoleIsr)(char)

function pointer (in hal file) for the function that gets called when a byte is received on the debug console.

unsigned char rfTestChannel = RF_TEST_CHANNEL_MIN

The current channel that the RF test mode is set to. Stored so that we can increment/decrement this channel easily. Change this if you want the application to start on a different channel.

unsigned char rfTestMode = RF_TEST_UNMODULATED

Which RF Test Mode we're in. Will be changed by the commands. Change this if you want the application to start in a different mode.
