Using IR module & nbsp; de2-115 development board is equipped with an IR module (model: irm-v538n7 / Tr1), and the relevant circuit diagram can be found in de2-115 system CD-ROM_ 115_ datasheet\IR_ Found in the receiver directory. It should be noted that this integrated receiving module is only compatible with 38kHz carrier pulse width modulation mode. The remote controller encoded with upd6121g chip can generate the modulation signal matching with the receiver.
