ARDUINO Functions Remote Control - IFI

Functions and Variables → Remote Control - IFI

Color Key Function: Variable:

bVEXNETActive

const bool bVEXNETActive

(bool) Boolean flag indicating whether VEXNET WiFi or legacy 75 MHZ RF wireless transmission is used.

if(bVEXNETActive = true) { // Vexnet is active }

nIfiSPIMsgCounts

const word nIfiSPIMsgCounts

(word) Variable counts the number of SPI messages received by the user CPU from the master CPU.

while(nIfiSPIMsgCounts < 500) { // Less than 500 SPI messages have been sent. }

nVexRCReceiveState

const TVexReceiverState nVexRCReceiveState

(TVexReceiverState) Integer value representing the current state of the transmitters connected to the VEX. This variable will return a different value depending upon the current configuration of remote transmitters connected to the VEX controller.

bIfiAutonomousMode = false; int statusbit = 0;   while(true) { statusbit = nVexRCReceiveState; wait1Msec(25); // No Crystals = 0 // One Transmitter = 1 // Two Transmitter = 2 // One and Two Transmitter = 3 // One VEXnet = 8 // Two VEXnet = 10 }

vexRT

const word vexRT[TVexJoysticks joystickOrButton]

(word) Array that contains the values of the joysticks and buttons from an VEX RF Transmitter. Supports channels Ch1 through Ch6. Returns values between -127 and 127 (normalized for motor values in ROBOTC.)

Parameter Explanation Data Type joystickOrButton A joystick channel or button channel. TVexJoysticks

while(true) { motor[port2] = vexRT[Ch2]; //Motor port 2 speed is determined by Ch2 on the Remote Transmitter motor[port3] = vexRT[Ch3]; //Motor port 3 speed is determined by Ch3 on the Remote Transmitter }
