Looking at my new optical system, my processor will take around 128uS to
read 4 channels. If I turn on my set of 4 IR LEDS for 128uS, and reading in
sets of 4 giving a 50% mark-space ratio, how do I go about calculating how
much current I can dump through the LED's without cooking them. In other
words what do I need to know andtake into consideration.
