Setup and Code the Remote Device
PIC32MX Atomic Port I/O Operations
TRISxSET - TRISxCLR
PORTxSET – PORTxCLR - PORTxINV
LATxSET – LATxCLR – LATxINV
TRISACLR = 0x0001 RA0 = OUTPUT
TRISASET = 0x0001 RA0 = INPUT
LATASET = 0x0001 RA0 = 1
LATAINV = 0x0001 RA0 = 0

15. A Basic4Android Wireless Digital I/O App
Setup and Code the Remote Device
Step 1: Define the WF32 LEDs 5 and 6.
Step 2: Code the LED Command Handler.
TRISFCLR = 0x0001; //WF32 RF0 = OUTPUT - LED5
TRISGCLR = 0x0040; //WF32 RG6 = OUTPUT - LED6
if(CharInQueue()) //print received character {
biteIn = recvchar();
switch(biteIn)
case 0x35:
LATFINV = 0x0001; //LED5
break;
case 0x36:
LATGINV = 0x0040; //LED6 }
This code is added to the main function of the EDTP Embedded Bluetooth Driver.
