Assuming I am OK with setting up a 555 bases pwm (53kHz) to run a few IR LEDs and that I can get an unmodulated IR LED and phototransistor to drive a red LED as an indicator as you pass your hand over the phototransistor. What is the best way to go about demodulating a 50kHz IR signal coming from the phototransistor. I have tried a high pass
Why don't you refer to known working IR remote control protocols like RC5? Why not generating the 38k in software respectively by a pwm output? You definitely don't need analog components besides IR-diode, current limiting resistor and IR receiver.
i/p-pwm throttle control. TTl level pwm throttle control wita base frequency of 2khz and a duty cycle rangining between 10%-90%. 10% full reverse. 90% is full speed. 50%is stop. o/p-decoded throttle control. A two-bit TTl logic signal, one bit indicating direction(0/1), other bit a pwm TTL signal(0-100%). please help
Hi! I don't have a background on VHDL/FPGA until last month when i started to self-study because there is a design contest in our school. Part of the contest is designing a pwm Encoder having 8 bits of input from an ADPCM decoder and the pwm Encoder is fed with a PCM. The output of the pwm Encoder is also 8 bit. I (...)
Hi , Does anybody have any code written in C to decode the pwm output of a RF remote control (from a car alarm) . Doesn't have to be code hopping just read the code so that I can display it . Thanks in advance Schmitt :lol: :lol: :lol:
