hi
i want a 38 khz square wave generated as a carrier frequency for ir transmitted.
but i am not able to do so using 8051, i tried doing but it does not give me more than 1khz square wave.
please help me in doing this.
Is it meaning that i need to use 8051/or timer555 to generate a 38kHz pulse so that TSOP1138 can give the output that i wanted ? By the way, i use one pair of IR sensor for the front sensor of my mobile robot
Thank you
