The AC164124 is a IrDA PICtail Plus daughter board designed to operate in conjunction with explorer 16 boards or other development boards with a PICtail Plus connector and AN1071 IrDA standard stack for 16bit microcontrollers to create an IrDA enabled development and evaluation platform. The IrDA stack is written to operate with the IrDA enabled UARTs on the PIC24F, PIC24H, and dsPIC33 16bit controllers and digital signal controllers. The IrDA Standard PICtail Plus daughter board can be used in conjunction with the IrDA Standard Stacks for 16bit and PIC32 microcontrollers. To get started, an explorer 16 development board is required. All explorer 16 development boards are shipped with connector J5 installed. The IrDA Standard PICtail plus daughter board should be inserted into one of the top two sockets of J5. The orientation of the IrDA Standard PICtail Plus daughter board should be such that the optical sensors points toward the prototyping area on the explorer 16 development board
