Hello Forum,
I dont have experience wit IR communication . I am employing it in an automotive application BUS Transit . I intend to communicate directionaly the status of fuel/coolent inside the BUS from side ways through fixed transponders .
The Bus may be at 60Km/H speed but distance is less 2meter . Is it possible to collect data at this speed with IR system? . The data being 6 digit number. I am unable to use RF as it isnt directional and will confuse between two Buses as the onboard transmitters will always be in ON state working as simplex configuration to cut the time required in protocol exchange. Also from so many Buses it would also be difficuly for RF fixed transponder to maintain a search and slave enumiration .
I see a lot of circuits employing 555 timer and RC oscillators for carrier generation. I feel these arent that precise as the ceramic resonator isnt there . Is it ok to use 555 or RC oscillator for this much distance ? . I plan for 38KHz carrier frequency. How can we generate 38KHz precisely for this application ?
Please advise.
Regards
PS: there is already too much load on my MCU that it wouldnt be possible to generate 38KHz .
