3.9.1.9 IR
IR here means the transmission and reception of infrared. System has specific I/O assigned for the
transmitting or receiving pin, but user must assign the length of IR coded data and the IR carrier
frequency.
IR Mode: select TX or RX mode.
IR Data Length: select the length of IR coded data.
IR CRC: select the bit length of IR CRC (Cyclic Redundancy Check), the default is “No”.
IR Frequency: select the IR carrier frequency.
IR Carrier: select NPN or PNP transistors as driver for IR LED.
TX Pin: select TX pin. Only in NY5 / NY5+ / NX1 EF can be selected.
RX Pin: select RX pin
Ex.
IR_Mode
= TX+RX
IR_Bit
= 8
IR_CRC =
2
IR_Freq
= 38.5K
IR_Carrier
= High
IR_TX
= PA.0
IR_RX
= PA.3
Note: NY9T does not support the related IR options.
